+Distinguishing Features +

+

Easily overlooked in out of the way habitats, Anthelia julacea grows as tiny (<.5 mm wide) overlapping shoots packed into silvery, horizontal turfs on bare rock in areas of late snow and seasonal flushes. With a hand lens, you should see three rows of tightly overlapping, sharply and evenly two-lobed leaves divided to about 1/2 their length and fringed with white edges against a darker inner leaf. This species is impossible to confirm without microscopic examination of fertile shoots.

+

+Similar species +

+

Anthelia’s small size, dense cushions, silvery palour, evenly bilobed leaves and affinity for bereft bedrock only overlaps with species in the genus Gymnomitrion. Plants of that genus often bear acutely bilobed, white and tightly overlapping leaves, but they are typically wider (>>.5 mm) and are dissected to only 1/3rd their length. They also lack the prominent third row of leaves seen in Anthelia. Differentiation of the two regional species of Anthelia requires the presence of fertile plants in a population. When present, the androecia and gynoecia are on seperate plants in A. julaceae, while in A. juratzkana, they are on seperate branches of the same shoot. If sporophytes are present, it should be noted that the spiral bands of the elaters in A. juratzkana are <3 um wide, while those of A. julacea are >3 um wide.

+Distinguishing Features +

+

A cryptic species of decaying wood and organic matter, Bazzania ambigua typically presents as green-to-brown horizontal shoots (~2 mm wide) that fork evenly. The arched lateral leaves have two very shallow tooth-like lobes (<1/10th leaf length) at their tips, while the underleaves are about as wide as long and bear 3-4 shallow lobes with rounded tips. The lateral leaves of fresh material should be looked at under the microscope; there should be 2-4 oil bodies in the cells if the identification is correct.

+

+Similar species +

+

See notes under Bazzania denudata, a lookalike that dominates in the same habitat. That species has 3-lobed lateral leaves, underleaves wider than long and oil bodies 8-12 in the leaf cells. B. ambigua typically has 2-lobed lateral leaves, underleaves about as wide as long and oil bodies 2-4 in the leaf cells.

+

+Habitat +

+

Moist to mesic humus, rock outcrops, cliffs, boulders, tree trunks, branches, and decayed wood in the lowland and montane zones

+Distinguishing Features +

+

The most common member of the genus, Bazzania denudata typically presents as emerald-green horizontal shoots (~2 mm wide) that fork evenly and, as the species name indicates, often drops its leaves along portions of the stem. The arched lateral leaves have three very shallow tooth-like lobes (<1/10th leaf length) at their tips, while the underleaves are wider than long with 3-4 lobes with rounded tips. The naked shoot sections stand out in particular, especially on plants found in extensive carpets on conifer trunks, stumps and logs.

+

+Similar species +

+

The evenly-forked shoots and notch-like lobes at the tip of the lateral leaves make it unlike any species outside its own genus, though Calypogiea species are often found in the same habitat and can mimic the leaf form. Bazzania denudata has 3-4 lobes on its underleaf, however, while species of Calypogeia have 2 at most. B. tricrenata and B. griffithiana are brown-to-yellow species with significantly longer shoots (>3 cm). Bazzania trilobata is emerald green like B. denudata, but the shoots are much wider (3-6 mm vs. 2 mm) and its underleaves have toothed crests, not rounded ones. B. pearsonii, a species of similar size and colour to B. denudata, has unlobed underleaves. Bazzania ambigua typically shows 2-lobed lateral leaves and underleaves that are as long as wide, while B. denudata has (typically) 3-lobed lateral leaves and underleaves that are wider than long. If uncertain, check the lateral leaves with a microscope: oil bodies are 8-12 in B. denudata and 2-4 in B. ambigua.

+Distinguishing Features +

+

A rare species in highly restricted habitat, B. griffithiana forms large, loosely-branched scrambling yellow-to-brown shoots up to 8 cm long. Its triangular lateral leaves have three short, tooth-like lobes at their tip, while underleaves are squarish with bases that run down the stem and 3-4 very shallow round lobes at their tips. Unmistakeable on account of its size and palour, this is a species to be sought in very moist coastal regions of British Columbia and Alaska, though currently only known from Haida Gwaii.

+

+Similar species +

+

With the genus Bazzania, only B. trilobata and B. tricrenata approach the scale of B. griffithiana. B. trilobata is a actually broader (leafy shoots 3-6 mm wide), but its translucent green colour also sets it apart from yellow-to-brown B. griffithiana. B. tricrenata is also a yellow-to-brown species and its shoots can reach considerable lengths (up to 4cm), but it has prominent pale and relatively leafless branches arising from its underside, whereas in B. griffithiana, such branches are absent. Mastigophora woodsii and Lepidozia filamentosa are also large, wide-branching and scrambling liverwort species but their leaves are highly dissected, while in B. griffithiana the lateral leaves are very shallowly notched.

Loping over peaty grounds, decaying organic matter, tree trunks and bedrock, B. tricrenata is a predominantly yellow-brown species with shoots up to 4 cm long found in a startling range of habitats. The lateral leaves have 3 small, tooth-like notches at their tip, whilst the underleaves have 3-5 short, knobby lobes at their tip. Inspection of the underside of the plant should reveal numerous pale-white or brown branchlets (up to 3 cm long!) emerging from the stem.

Only Bazzania trilobata has similair long pale branchlets emerging from its underside, but it is a bright green species with wide leafy shoots (3-6 mm), whereas B. tricrenata is yellow-to-brown and its shoots are <3 mm wide. The rare and similairly-coloured B. griffithiana could occur in the same wet and peaty habitats, but it lacks does not bear the long pale branchlets seen on the underside of B. tricrenata.

Blepharostoma arachnoideum is a rare liverwort of very moist peatlands and creekbanks, where its transluscent green and delicately-branched leaves emerge from very narrow (<1/4 mm wide) shoots. The leaves are formed of 2-3 linear segments that are divided all the way to the base of the leaf. Close inspection shows that these linear segments are one cell wide and in turn tend to branch.

+Distinguishing Features +

+

Delicate and filamentous plants of Blepharostoma are frequent but easy to overlook in their moist microhabitats, where they occur as transluscent yellow-to-green bristly shoots <1/4 mm wide that creep along the substrate. With a hand lends the leaves are composed of four equal and linear lobes that are seperated all the way to the very base of the leaf. Under the microscope, these lobes are only one cell wide.

+

+Similar species +

+

Species of Kurzia are of similair size with 4-lobed leaves and can occur in similair habitats. The leave lobes in that genus, however, are 1-celled at their tip but broaden to 2 (or more) cells wide towards their base, which is found at about three-quarters down the leaf’s length. In B. trichophylla, the leaf lobes are always 1 cell wide and are divided all the way to the very base of the left. Differences with Blepharostoma arachnoideum are subtle– the latter tending to have 2-3 lobes that often branch further along their length, while in B. trichophyllum, there are typically 4 (sometimes 3) lobes that are never branched. B. trichophylla is often treated as a complex of closely related taxa with intergrading morphologies.

A frequent species in the damp, dark and wet coastal coniferous forests in which it thrive, Calypogeia azurea occurs as a small, creeping blue plant on decaying organic matter. The round lateral leave overlap one another like shingles on a roof ("incubuous"), while the underleaves are two lobed and divided to about half of their length. The characteristic blue hue can be subtle, but it is a manifestation of the aquamarine oil bodies that are clearly visible under the microscope.

+

+Similar species +

+

With round, overlapping leaves, C. azurea could only be mistaken for other species in the genus Calypogeia, most of which can be distinguished on the basis of the underleaf shape. Of these, only Calypogeia mulleriana has an underleaf that is similairly divided to about half its length, but it lacks the blue hue of C. azurea.

+

Decaying organic matter, especially wood in wet coastal forests.

An infrequent species of creek and drainage banks, C. integrispula forms linear shoots >2 mm wide composed of two rows of round, opaque green leaves overlapping in a shingle-like arrangement. The key distinguishing feature of this species is the underleaves, which are typically undivided, though sometimes with a very shallow sinus. While inspecting the underleaves with a hand lens, note the presence of transparent cells at the margins of the lateral leaves in contrast to the opaque cells further in from them.

+

+Similar species +

+

Looking at the top of the shoots, C. integrispula could be mistaken for the C. muelleriana, C. suecica or C. azurea, but all of those species will show a clearly divided and lobed underleaf on the undersides of the shoot. Only C. neesiana has an underleaf that is undivided like that of C. intergrispula. To distinguish between the two species, microscopic examination is neccessary to makeout the presence of oil bodies in the underleaves of C. integrispula, a feature lacking in C. neesiana.

+Distinguishing Features +

+

The most common species of the genus Calypogeia in our region, C. mulleriana is a dark green leafy liverwort with linear shoots (~2mm wide) composed of round leaves that tightly overlap like shingles on a roof ("incubous"). Typically tightly appressed to decaying conifers and organic-rich soils, this species can be confirmed by hand lens examination of the underleaf, which should show two lobes that are divided to about half of their length. Like many species in the genus, C. mulleriana frequently has gemmae-bearing shoots that have more distant leaves and erect shoot apices with light-green clusters of asexual spores.

+

+Similar species +

+

Calypogeia mulleriana is unlikely to be confused with any other genus of leafy liverworts with the exception of Bazzania, which can show similair shingle-like arrangement of leaves. That genus, however, has leaves that have tooth-like notches at the tips and underleaves with more than two lobes. The green, rounded leaves and evenly two-lobed underleaves of C. mulleriana are similair to many species in the genus Calypogeia, but can be distinguished from other species with a hand lens. Plants of C. azurea have identical leaves and underleaves, but have a blue hue, while C. sphagnicola has leaves that are triangular in shape and do not overlap, whereas leaves in C. mulleriana are round and tightly overlap. C. integrispula and C. neesiana have unlobed underleaves and C. fissa has an underleaf dissected almost all the way to its base, while the underleaf in C. mulleriana is only dissected to about half of its length. C. suecica, a rare species of wet wood, is very small (typically <1 mm wide) and has somewhat pointed underleaves relative to the rounded underleaves of C. meulleriana, which occur on shoots typically >2 mm wide.

With its rounded, mostly undivided underleaf, this species could only be mistaken for C. integrispula, a larger species (~2.5 mm wide) that occurs in the same damp habitats. The distinction is microscopic: C. neesiana has underleaves with bases that run down the stem ("decurrent") and stem cells that lack oil bodies, while C. integrispula has oil bodies in its stem cells and the underleaves are not decurrent.

An infrequent species of wet, peaty banks, the light green and relatively large Calypogeia fissa forms long shoots (> 2cm) that loosely weave through other bryophytes. The leaves are somewhat distant and have a rounded-triangular shape and apices that are often notched. The underleaves are diagnostic as they are deeply divided to within a few cells of the base.

+

+Similar species +

+

The leaves of C. fissa might be mistaken for Bazzania on account of the notches at their tip, underleaves in the former are always two-lobed and deeply divided, whilst species of Bazzania have underleaves that are typically 3-4 lobes and shallowly divided. No other species in the genus Calypogeia has such a deeply divided underleaf and as such C. fissa is unmistakeable upon inspection with a hand lens.

Tiny translucent green (~1mm wide) threads of Calypogeia sphagnicola are a frequent but easily overlooked component of bogs and fens, where they grow in and amongst the Sphagnum. Upon inspection with a hand lens, you should see distantly arranged, somewhat elongate leaves that are frequently notched at their tip. Underleaves are divided to about half of their length and show somewhat narrow lobe tips.

+

+Similar species +

+

Quite a few small leafy liverworts make their home in Sphagnum, however species of Gymnocolea, Cephalozia and Cephaloziella all have leaves that are deeply two-lobed, whereas those of C. sphagnicola are very shallowly-lobed if at all. Both Mylia taylorii and M. anomala can grow between Sphagnum, but both species have large (>2mm) oval-shaped leaves that point upwards, whereas those of C. sphagnicola are small (<1mm), rounded-triangular and tend to point out at 90 degrees from the stem. In the genus Calypogeia, only C. integrispula and C. fissa are likely to occur in the same habitat, but both of those species are larger (shoots ~2mm wide) and have distinct underleaves (unlobed in C. integrispula, deeply lobed in C. fissa) that differ from the halfway-lobed form of C. sphagnicola.

A rarely noticed species of decaying wood in coniferous forests, C. suecica is a tiny (~ 1 mm wide) pale-green plant with two rows of round leaves that overlap in a shingle-like fashion. Close inspection with a hand lens should reveal an underleaf that is dissected to about half of its length and crowned by 2 or 4 somewhat sharp apices.

+

+Similar species +

+

On decaying wood, C. suecica is most likely to be mistaken for C. muelleriana and C. azurea, both of which are bigger species with identical leaf arrangement on the tops of the shoot. C. azurea is easy to distinguish on account of its blue hue, but smaller plants of C. muelleriana will look very similar and may need microscopic examination to detect subtle differences in underleaf shape (more acute in C. suecica) and oil body form (segmented oil bodies are known in both species, but only C. suecica has them alongside simple oil bodies).

+

A rarely observed species unique in the genus on account of being XXX, C. ambigua forms small green-brown shoots (~ .5 mm wide) of diagonally-inserted bilobed leaves that are wider than the stem. The leaves are attached diagonally and their bases converge near the midline of the upper stem face. Microscopic measurement of the leaf cells is required to distinguish this species from C. bicuspidata.

+

+Similar species +

+

The diagonally inserted leaves that converge near the midline of the stem seperate it from all species in Cephaloziaceae except for Cephalozia bicuspidata. While C. bicuspidata is generally a larger species (shoots ~ 1 mm wide), confident determination requires microscopic examination of the leaves. Cells at the base of the leaf lobes in C. ambigua are < 24um wide, while those of C. bicuspidata are > 24 um wide. Underleaves are occasionally present in C. ambigua and always absent in C. bicuspidata.

+

+Habitat +

+

On rock and montane peat.

+Distinguishing Features +

+

A very common species, Cephalozia bicuspidata forms bright, creeping, translucent green shoots 1-2 mm wide on decaying wood and peat in wet forests and bogs. Inspection with a hand lens shows two rows of sharply bilobed leaves, the leaves themselves slightly wider than the stem and attaching at their bases nearly at a right angle across the stem and very close to its midline. Sporophytes are frequently present and can be found developing in or extruding from elongate, ridged, whitish-green and erect pouches.

+

+Similar species +

+

This species frequently coocurs with a number of lookalikes. Lepidozia reptans is of similar size, colour and habitat, but has clearly 3-4 lobed leaves, whereas C. bicuspidata leaves are 2-lobed. Species of Cephaloziella are typically a little smaller, but can be clearly seperated out by leaves narrower than the shoot as opposed C. bicuspidata, where the leaves are wider than the shoot. Species in the genus Fuscocephaloziopsis are similar in scale, habitat and the presence of bilobed leaves, but those leaves are attached along the length of the stem, whereas in C. bicuspidata, the leaves are attached obliquely across the stem. Cephalozia ambigua is treated often as a subspecies of C. bicuspidata, the former differing in its smaller size (~ .5 mm wide) and the presence of underleaves which are absent in the latter. C. macounii is somehow much smaller (<< .5 mm wide) very similar, but microscope inspection of the leaf should show very oblique attachment to the stem, whereas in C. bicuspidata leaves verge on attaching at a right angle across the stem axis.

A rare species forming tiny threads <<.5 mm across, C. macounii will need microscopic examination to identify (if not detect!). The bilobed leaves are the same width as the stem and divided more than half of their length, the lobes themselves only two cells wide. Under the microscope, the cells of C. macounii lack oil bodies.

+

+Similar species +

+

On tiny leaf and shoot size alone, this species could be mistaken for a Cephaloziella or Eremonotus, but species in those genera bear oil bodies in their leaf cells, while such oil bodies are lacking in C. macounii. Species of Fuscocephalozia have small, bilobed leaves, but lobes of these leaves more than two cells wide and the leaves themselves are attached along the stem such that their lower edge runs down the shoot ("decurrent"). Cephalozia ambigua and C. bicuspidata are larger species (>>.5 mm wide) and have leaves visibly wider than their stems.

+Distinguishing Features +

+

Small enough to evade notice (<.5 mm wide) but ambient enough to be found in almost any habitat, C. divaricata varies from green to black in colour and solitary threads to dense tufts in growth habit. The vegetative leaves are smaller than the shoot diameter and are sharply two-lobed to about 1/2 or 3/4 leave length and fairly smooth along their edges. Microscopic examination should be used to confirm this latter character as well as the presence of oil bodies.

+

+Similar species +

+

Sphenolobopsis, Marsupella, Cephalozia and Fuscocephaloziopsis can be of similair size and leaf form, but the leaves in those genera are wider than the stems and have oil bodies, while in C. divaricata oil bodies are lacking and the leaves are narrower than the stem. Eremonotus myriocarpus is very similar in size, leaf shape and threadlike growth habit. It grows in the very specific habitat of damp vertical rock, but otherwise requires granular examination of the shoots to compare leaf shapes and reproductive structures- see photos under that species. Other species of Cephaloziella (C. phyllacantha, C. spinigera, C. turneri, C. elachista) in this region have leaves divided almost to their bases in addition to prominent teeth along the leaf margins. Vegetative leaves of C. divaricata are divided to about half their length and typically without teeth. The remaining species will need to be parsed based on the arrngement of their reproductive organs. In Cephaloziella divaricata, the modified leafy structures that bear the archegonia ("gynoecia") and antheridia ("androecia"), while in C. rubellum, C. varians and C. hampeana, they can be found on the same shoots.

+

One of two exclusively "Sphagnicolous" species in the genus, C. elachista is easily overlooked as wayward pale green hair or algae-like strands (< 1/4 mm wide to cms long) weaving their way through Sphagnum in open boggy areas. Maybe with a hand lens but more likely with a microscope, you will see deeply divided 2-lobed leaves with sharp apices and tooth-like projections arising from their base. Under the microscope, the lobes themselves are 2-4 cells wide at their base, with teeth restricted to that lower margin and thin leaf cell walls.

+

+Similar species +

+

At the small scale and specialized habitat that C. elachista grows in, only species of Cephalozia, Fuscocephaloziopsis and Cephaloziella could be confused. The first two genera are typically "bigger" plants, with leafy shoots measuring >.5 mm wide and the leaves themselves visibly wider than said shoots. Leafy shoots of C. elachista are ~1/4 mm wide and the leaves themselves narrower than the shoots. Cephaloziella divaricata can grow in the same habitat, but its leaves are only divided to half their length, while those of C. elachista are divided almost to their base. C. spinigera also occurs in the same habitat and is impossible to distinguish without a microscope– its leaf cells are wider (9-12 um) and its cell walls thinner than those of C. elachista (see photo).

Poorly known in the region but cosmopolitan across the temperate and boreal regions of the Northern Hemisphere, Cephaloziella hampeana follows standard green-to-red, small thread-like growth form seen in most member of the genus. Under the land lens, the unornamented spreading leaves are lobed with a sinus descending to around half the leaf length. To distinguish this species from others in the genus, care must be taken to confirm the absence of underleaves as well as for gynoecia and androecia, which should be present on different branches of the same plant.

+

+Similar species +

+

At its size (leafy shoots less than .5 mm wide) with distantly spaced bilobed leaves, it could only be mistaken for other members within the genus Cephaloziella. C. turneri, C. spinigera, C. phyllacantha and C elachista all have leaves are dissected very near to their toothy or spurred bases, while C. hampeana has lobed, toothless leaves divided to only about half of their length. C. divaricata has underleaves on the shoots and androecia and gynoecia on seperate plants; underleaves are absent on C. hampeana and its gynoecia and androecia are on the same plant. C. varians has round lobe tips on erect leaves where those of C. hampeana are acute on wide-spreading leaves. C. rubella, the last species that it could be confused for in the region, has erect leaves and androecia and gynoecia close together on the same shoot in contrast to their arrangement on seperate branches in C. hampeana, which has wide-spreading leaves.

A rare cryptic species of very damp rock and soil near waterfalls where it threads its way through other, larger bryophytes, Cephaloziella phyllacantha is a whitish green and toothy plant so small that it is unlikely to be detected without a microscope. The deeply lobed leaves (to within a few cells of their base) are flamboyantly toothed, with tall conical papillae over many of the leaf cells (see image) that are unique to this species.

+

+Similar species +

+

Cephaloziella turneri, C. elachista and C. spinigera all have deeply divided leaves with somewhat prominent teeth, as in C. phyllacantha. All of these similar species lack the conical papillae under the microscope. Its also useful to know that they grow in very different habitats- C. turneri in seasonally hot and dry areas, while both C. elachista and C. spinigera are "Sphagnicolous", growing between the shoots of Sphagnum in bogs and fens.

A perplexing species with a reddish hue, Cephaloziella rubella has very narrow (~1/4 mm) leafy shoots. Under the hand lens, you should see leaves divided to about half their length with sharp lobe apices and smooth margins. Vegetative shoots should be completely devoid of underleaves and the antheridia and archegonia (when present) should be close to one another on the same shoot.

+

+Similar species +

+

See notes under C. divaricata, the species it is most likely to be confused for. That species has underleaves on its vegetative shoots and antheridia and archegonia are found on seperate plants, whereas in C. varians underleaves are present on vegetative shoots and archegonia and antheridia are found on the same shoots.

+Distinguishing Features +

+

One of two exclusively "Sphagnicolous" species in the genus, C. spinigera is easily overlooked as wayward pale green hair or algae-like strands (< 1/4 mm wide to cms long) weaving their way through Sphagnum in open boggy areas. Maybe with a hand lens but more likely with a microscope, you will see deeply divided 2-lobed leaves with sharp apices and tooth-like projections arising from their base. Under the microscope, the lobes themselves are 2-4 cells wide at their base, with teeth restricted to that lower margin and thick leaf cell walls.

+

+Similar species +

+

At the small scale and specialized habitat that C. spinigera grows in, only species of Cephalozia, Fuscocephaloziopsis and Cephaloziella could be confused. The first two genera are typically "bigger" plants, with leafy shoots measuring >.5 mm wide and the leaves themselves visibly wider than said shoots. Leafy shoots of C. spinigera are ~1/4 mm wide and the leaves themselves narrower than the shoots. Cephaloziella divaricata can grow in the same habitat, but its leaves are only divided to half their length, while those of C. spinigera are divided almost to their base. C. elachista also occurs in the same habitat and is impossible to distinguish without a microscope– its leaf cells are narrower (< 9 um) and its cell walls thicker than those of C. spinigera (see photo).

The "biggest" species in the genus (shoots to about .5 mm wide and 1 cm long), Cephaloziella turneri is an infrequent yellowish green-to-brown presence in summer dry rocky habitat, where it can be found on often-disturbed thin soil over balds and in crevices. The leaves are deeply bilobed (dissected more than 3/4 of the leaf length) and generously toothed from base to tip. Angular red gemmae are frequently present at the shoot tip.

+

+Similar species +

+

C. turneri can grow alongside C. divaricata, but leaves or that species are not toothed from top to bottom. The other toothy species of Cephaloziella occur in much wetter habitats (bogs for C. elachista and C. spinigera, permanently moist rock ledges for C. phyllacantha).

Common in habitats that are at least seasonally inundated with water, this species has large pale-green, delicate and square leaves that spread out from their attachment roughly along the long axis of the stem. The tips of the lateral leaves are rounded or blunt, occasionally with a shallow and round notch, while the underleaves are very narrow but discernably two-lobed with a hand lens. When fertile, this species has archegonia and antheridia on seperate plants; species recognition here requires observation of the leaves surrounding the archegonium, which should be toothed at their tip. Alternately, you can look to make sure that there are typically 3 oil bodies per leaf cell.

The longitudinal attachment of blunt, simple leaves in habitats that often host water winnows the list of liverworts for which this could be confused. Gyrothyra underwoodiana is a species of wet banks with similair leaves and leaf attchment, but its undersides have a characteristic set of discrete purple "pads" that are absent in Chiloscyphus pallescens. Species of Jungermannia and Solenostoma have simple leaves, but they are attached at a more oblique angle and both genera lack the underleaves of Chiloscyphus. Species of Plagiochila can have similair oblique-longitudinal attachment of unlobed leaves, but those leaves typically have teeth and the plants never have an underleaf. C. pallescens has an underleaf and its leaves are unadorned. Lophocolea heterophylla typically has leaves showing variable degrees of lobing along the length of the stem, but when the leaves are unlobed, they can look like Chiloscyphus, but C. pallescens does not show much variation in leaf form along the stem. Chiloscyphus polyanthos has leaves and stems that are morphologically indistinguishable from C. pallescens. Close inspection of the leaves surrounding the archegonia in fertile material should show smooth leaf margins in the former and teeth on the latter, while microscopic examination will show most leaf cells of C. polyanthos have 2 oil bodies, while those of C. pallescens mostly have 2 oil bodies.

With relatively wide (> 1 mm) and worm-like pale green shoots clustering amongst and growing through Sphagnum in subalpine areas, F. albescens takes some work to see. The round, shallowly lobed and concave leaves are much wider than the stem and standout as unique in their habitat, especially when paired with a long, unlobed and utterly visible (at least with a hand lens) underleaf. Under the microscope, oil bodies should be absent.

+

+Similar species +

+

Genera like Gymnomitrion and Harpanthus are also subalpine, pale and two lobed, but neither of those species have the concave, cupped-shaped leaves of Fuscocephaloziopsis albescens. Cephalozia bicuspidata has similar leaf attachement, but lacks an underleaf its lateral leaves are elongate and deeply bilobed, whereas in F. albescens they are round and shallowly bilobed. No other species in the genus Fuscocephaloziopsis has an underleaf.

+

+Habitat +

+

Subalpine meadows on soil, hummus & Sphagnum.

Fuscocephaloziopsis connivens is a common species typical of wet wood and decaying organic matter, on which its small (~ 1 mm wide) translucent green shoots creep. The two lobe tips in this species point towards one another, often touching or crossing as they converge. Paired with leaf attachment along the length of the stem and a lower leaf base that runs down the stem, F. connivens is unmistakable.

+

+Similar species +

+

Likely to be confused only with F. lunulifolia and F. pleniceps, both of which are species that also feature round, two-lobed leaves with acute tips that are attached along the length of the stem such that their lower bases run down the shoot. Neither of these species, however, have tips that converge with one another as they do in F. connivens.

Close inspection show a two-lobed leaf with sharp apices that is divided to about 1/3 its length and attached along the long axis of the stem such that its base runs down along the shoot ("decurrent"). The outward-pointing apices are an unreliable indication of this species, so microscopic examination is required to see the thickened outer wall of the cell at the lobe tip and the decreasing cell size in the leaf from base to sinus.

+Similar species +

+

Likely to be confused only with F. connivens and F. pleniceps, both of which are species that also feature round, two-lobed leaves with acute tips that are attached along the length of the stem such that their lower bases run down the shoot. F.connivens has lobe tips that tend to point towards if not touch or cross one another, while in F. lunulifolia, the lobe tips are not so convergent. F. lunulifolia is very similar to F. pleniceps, but under the microscope it has outer walls of the terminal lobe cells much thicker than the inner wall, whilst in the latter the wall is evenly thickened all around.

+Distinguishing Features +

+

F. monticola is an infrequent species forming relatively dense albeit small turfs of stiff, compressed dark green shoots up to 3 mm wide along slopes in the high subalpine. Upclose, it has a succulent stem, leaves that are shallowly two-lobed or occasionally even three-lobed and underleaves can be present, though they are typically obscured by a dense set of hairs ("rhizoids"). Under the microscope, this species lacks oil bodies and can exhibit green, two-celled gemmae produced along young leaf tips at the shoot apex.

+

+Similar species +

+

On account of its large size and very compressed shoots, it is unlikely to be mistaken for any other member of Cephaloziaceae. In its habitat, however, it can coocur with species of Lophozia and Tritomaria that are superficially similair. Neither of these genera exhibit the dark green colour and deeply, symmetrically compressed shoots of F. monticola.

+Distinguishing Features +

+

Forming tiny (< 1mm wide), translucent shoots in peaty areas, F. pleniceps is an often overlooked and ergo uncommon bilobed leafy liverwort species. Hand lens inspection of the leaf should show them attached along the length of stem, with the bottom edge running down the shoot ("decurrent") and the lobe tips sharp before descending into a rounded sinus. Confident identification requires microscopy to count the number of cells across the leafs’ width (12-25) and note the even thickness of terminal lobe cells.

+

+Similar species +

+

Species of Cephaloziella can occur in peaty habitats, but they have leaves narrower than the stems they are borne on, whilst in F. pleniceps, the leaves are wider than the stems. In the family Cephaloziaceae, only F. connivens and F. lunulifolia exhibit leaves that attach down the length of the stem as in F. pleniceps. F. connivens tends to have lobe tips that converge on one another like a crab’s pincher, whereas those of F. pleniceps seldomly converge and tend to point upwards. F. lunulifolia is very similar to F. pleniceps, but under the microscope it has outer walls of the terminal lobe cells much thicker than the inner wall, whilst in the latter the wall is evenly thickened all around.

+Distinguishing Features +

+

Infrequent and easy to confuse with other two-lobed species, Geocalyx graveolens creeps loosely over its substrate, its yellow-green shoots bearing leaves that spread out widely (to 3 mm) from their longways attachment to the stem. The lateral leaves are shallowly-lobed (less than 1/4 the leaf’s length), their tips sharp but triangular, while the underleaves are clearly visible with a hand lens and are also clearly two-lobed. When sporophytes are present, they emerge anomalously along the underside of the shoot.

One of the few liverworts to truly match its common name, G. coralloides presents as a lawn of densely compressed, pale whitish-green, rounded shoots to 2 cm tall by 2.5 mm wide not unlike a colony of tightly-packed corals in high elevation or high latitude areas. The leaves have two equal, rounded lobes and are tightly overlapping ("imbricate"). For confident identification, you should expect the shoots to be compressed, not round.

Thriving on vertical rock faces, G. obtusum presents itself in dense tufts of downtrending white, wormy shoots up to 1 mm wide by centimeter(s) long. With a hand lens you should be able to make out individual bilobed leaves tightly overlapping one another on all sides ("imbricate"). The tips of the lobes in this species are rounded, the lobes themselves joining about 1/3 down the length of the leaf in a sinus that is sharply-angled.

A rare species of high altitudes and elevations, G. revolutum is variably red along its relatively wide (1-2 mm) and long (up to 5 mm) prostrate shoots of loosely overlapping leaves. The leaves are made up of two equal and rounded lobes, but along their sides that are "revolute"– they curl downwards (see photo). There are no oil bodies in the fresh leaves when inspected under the microscope.

In its ideal world of permanently moist decaying organic matter, K. makinoana presents itself as an almost imperceptiple transluscent dark green fuzz that calls to mind only one word: tiny. With a hand lens, the 3-4-lobes of each leaf are sharply tipped, converging at a leaf base that diverges from the stem at 90 degrees. In order confidently identify this species, a microscope is neccessary to observe the underleaves, which are typically reduced to 1-2 lobes accompanied by 1-2 amorphous bumps ("slime papillae"– see photograph).

+

+Similar species +

+

Sorting out species of Kurzia is always going to require high magnification on account of their small size. On account of its small size and tiny, almost filamentous leaf-lobes, K. makinoana can be mistaken for species of Blepharostoma or Lepidozia, both of which can occur in the same habitats. Blepharostoma species have leaf lobes that are 1-cell wide and divided completely to the base of the leaf. In K. makinoana, the lobes are 1-celled at their tip but broaden to 2 (or more) cells towards their base, which is found at about three-quarters down the leaf’s length. Lepidozia species have 3-4 lobed lateral leaves, the leaf itself being divided only to about 1/2 its length into lobes that are 4+ cells wide at their base. Kurzia pauciflora is a species exclusive to open bogs and has 4-lobed underleaves compared to the wider ecological range and 1-2 lobed underleaves of K. makinoana. Distinguishing K. trichoclados requires microscopic examination of the ornamentation of the leaves surrounding the developing reproductive organs.

Restricted to permanently moist, open bog habitats, variably green K. pauciflora forms a very fine (<1/4 mm wide) filamentous fuzz in and amongst the sprigs of Sphagnum. The underleaves and lateral leaves are similair in form (if not size), both 3-4 lobed and sharply-tipped, the lobes widening from 1 cell at their tip to 2 cells at their bottom before joining to a wide leaf base that is attached to the stem at 90 degrees.

Virtually identical to other members of its genus, K. trichoclados is a tiny (~1/4 mm wide) and easily-overlooked or mitaken yellow-brown species with highly dissected and barely-discernable leaves. Close inspection with a hand lens should show lateral leaves are similair with 3 to 4 sharply-tipped lobes that widen from 1 cell at their apex to 2 cells at their bottom before joining to a wide leaf base that is attached to the stem at 90 degrees. Underleaves are present but have only 1 or 2 well developed lobes.

+

+Similar species +

+

See notes under Kurzia makinoana. In order be certain you have K. trichoclados and not K. makinoana, you will need to look for specialized structures that bear the antheridia (Androecia) and archegonia ("Gynoecia") (see photos). In K. makinoana, the tips of the leaves surrounding the archegonia have hair-like cells ("cilia"), while the tips of the leaves surrounding the antheridia have two lobes. This is in contrast to K. trichoclados, where leaves of the gynoecia are toothed (no hair-like cells) and those of the androecia have three lobes.

Presenting as a luxuriant, regularly and closely branched yellow plume of a leafy liverwort, Lepidozia filamentosa can form large, feather-like patches of shoots up to 5 cm long bearing convex leaves. The lateral leaves and underleaves differ very little, as both typically have 4 triangular lobes that descend to about half of the leaf’s length and both are barely wider than the width of the stem. Under the microscope, the leaf lobes are wide at their base (9-15 cells).

+

+Similar species +

+

With 3-to-4 evenly lobed lateral leaves wider than the stem and feather-like branching, L. filamentosa is only likely to be mistaken for L. reptans, which can show regular branching and has very similair leaf form. The latter species is smaller (shoots are typically < 2cm long), but to be sure you can examine the leaves under the microscope. Leaves of L. filamentosa have lobes that are >8 cells wide at their base, while those of L. reptans are <8 cells.

Typically green or yellow-green, Lepidozia reptans is a dominant component of the decaying understories in coniferous forests, where it forms creeping and regularly-branched shoots about 1 mm wide and up to 3 cm long. The lateral leaves are wider than the stem and composed of 3 or 4 triangular lobes that are divided to less than 1/2 the leaf’s length.

In its habitat on decaying wood and tree trunks, it could be mistaken for species of Cephalozia and Fuscocephaloziopsis, but those all have 2-lobed leaves, whereas in L. reptans, the leaves are 3-to-4 lobed. Within the family Lepidoziaceae, species of Bazzania can have lateral leaves that are also 3-lobed, but the lobes are very shallow and constrained to the tips of the leaves, while in Lepidozia reptans, the lobes descend to about 1/2 the leaf’s length. Species of Kurzia have fuzzy-looking shoots about 1/4 mm in width and 3-to-4 linear leaf lobes descending to about 3/4ths of the way down. In L. reptans, the leaves are also 3-to-4 lobed, but the lobes are triangular, not linear, and descent to about 1/2 of the leaf’s length. It is most likely to be confused with the two other regional species of Lepidozia. L. sandvicensis has identical leaf shape, but the leaves themselves are narrower than the shoot and arranged very distantly from one another; leaves of L. reptans are wider than the shoot and are closely spaced to one another. It is most similair to Lepidozia filamentosa, but that XXXXXX

+Distinguishing Features +

+

A large,seemingly filamentous plant, Lepidozia sandvicensis presents as a minature transluscent green tumbleweed, its shoots up to 5 cm long with numerous long branches completely free from their substrate. While its lateral leaves have the genus’ characteristic 3-4 triangular lobes down to about 1/2 their length, they are narrower than the shoot width and very widely spaced along the stems. As the Latin name suggests, this is a plant with an interesting distribution, known predominantly from the Hawaiian Islands and wet-coastal British Columbia.

+

+Similar species +

+

Because of its large size and shoots growing free from their substrate, it is unlikely to be mistaken for other liverworts with leaves narrower than their stems (eg. species of Cephalozia and Cephaloziella, both of which have 2-lobed leaves). Species of the genus Kurzia have 3-4 lobed leaves as in L. sandvicensis, but they have shoots that only grow to less than 1 cm in length. Amongst the two other regional species of Lepidozia, L. sandvicensis is the only one with leaves narrow than the shoots on which they grow and it lacks the regular and even branching of L. filamentosa as well as the very close arrangement of leaves seen in L. reptans.

+Distinguishing Features +

+

Lophocolea bidentata occurs dependably on logs (amongst other substrates) as tightly appressed, light green and transluscent creeping leafy shoots to 3 mm wide and many centimeters long. The shallowly 2-lobed leaves are inserted roughly along the long axis of the stem, with their sharp and tapering apices seperated by a broad and round sinus. Narrow, two-lobed underleaves should be present and the lateral leaves maintain a consistent shape along the length of the stem.

+

+Similar species +

+

Species of Lophozia and Lophoziopsis have superficially similair leaves, but leaves in those species are not attached at their base along the long axis of the stem as in L. bidentata, nor do they have underleaves. Geocalyx graveolens does have nearly identical leaf attachment and bilobed shape, but its lobe tips are triangular, while those of L. bidentata have elongate, narrow tips. Species of Mesoptychia (especially M. gillmanii) can show similair leaf shape, but leaves in that genus are attached across the axis of the stem, not along it, and underleaves are unlobed, whereas in L. bidentata, they are bilobed. Within its genus, L. minor is smaller and has rounded, lobes covered in asexual spores ("gemmae"), while L. heterophylla has leaves that vary in form as you move along the stem, with some unlobed and those that are lobed varying between sharp and rounded lobe tips. L. bidentata is consistently sharply-lobed and gemmae on not present.

+Distinguishing Features +

+

Found on a variety of substrates in moist habitats, L. heterophylla grows tightly appressed and creeping, its light-to-dark green leaves spreading out like flags 90 degrees from the stem to form leafy shoots about 3 mm wide by many centimeters long. As implied by the species name, the shallowly bilobed leaves are quite variable along the length of the stem, with some leaves seemingly unlobed, some sharply bilobed and the rest falling somewhere in between. Underleaves are narrowly bilobed and can be seen with a handlens if not obscured by fine hairs.

+

+Similar species +

+

Species of Lophozia and Lophoziopsis have superficially similair leaves, but leaves in those species are not attached at their base along the long axis of the stem as in L. bidentata, nor do they have underleaves. Geocalyx graveolens does can have nearly identical leaf attachment and shape, but its leaves are consistent in shape along the stem and its lobe tips are always triangular, while leaves of L. heterophylla are variable in shape as you move along the stem, often without lobes or having lobes that are more blunt or more acute than those found in Geocalyx. Species of Mesoptychia (especially M. gillmanii) can show similair leaf shape, but leaves in that genus are attached across the axis of the stem, not along it, and underleaves are unlobed, whereas in L. heterophylla, they are bilobed. Within its genus, L. minor is smaller and has leaves with regularly rounded lobes covered in asexual spores ("gemmae"), while L. heterophylla has leaves that vary in form as you move along the stem and lacks gemmae. L. bidentata is consistently sharply-lobed and leaf shape does not vary along the length of the stem.

+Habitat +

Moist to wet, often shady humus, tree trunks, and decayed wood in the lowland, montane, and subalpine zones

+Distinguishing Features +

+

A small and easily-overlooked species of decaying wood, Lophocolea minor is a creeping species with pale yellow-green shoots roughly 1 mm wide to about 1 cm long. Like other members of its genus, L. minor has shallowly-bilobed leaves, but the lobes are rounded and typically covered in globs of asexual spores ("gemmae") that give the leaf a scuzzy look (see photo). This in combination with the narrow, bilobed underleaf make this species possible to recognize in the field with the aide of a hand lens.

+

+Similar species +

+

Because of its bilobed leaves, small size and wood-borne lifestyle, L. minor bears some semblance to species of Fuscocephaloziopsis and Lophozia. Lophozia longidens is also a species of decaying wood with asexual spores ("gemmae") on the leaves, but those spores are typically red and held in clusters at the tips of the leaf lobes. Furthermore, species of Lophozia lack underleaves. L. minor has narrow, bilobed underleaves and its gemmae are light green and arrayed all along the margins of the leaf. Species of Fuscocephaloziopsis are common on rotting wood and have longitudinal leaf insertion, but they lack the gemmae and bilobed underleaves found in L. minor. Within its genus, L. minor is the smallest and has rounded lobes covered in gemmae, while L. heterophylla has leaves that vary in form as you move along the stem, with some unlobed and those that are lobed varying between sharp and rounded lobe tips, all of which lack gemmae. . L. bidentata is consistently sharply-lobed and gemmae on not present.

+

Mylia anomala is seemingly restricted to bog and fen habitats, where it worms its way through Sphagnum, presenting at the surface as oppositely-arranged and converging elongate-oval leaves dusted with yellow-green asexual spores ("gemmae"), like a set of lips bearing a clump of cornmeal. Yanked from their substrate, the shoots are long (up to 3 cm), with the simple, unlobed leaves attaching obliquely to the stem and becoming more distantly spaced as you move down.

+

+Similar species +

+

This is the only large simple-leaved liverwort that grows exclusively through Sphagnum and has abundant yellow-green gemmae. The presence of prominent simple underleaves seperates it from Cryptocolea, Syzygiella, Jungermannia and Solenostoma. Because of its restriction to bog-like habitats, it could only be mistaken for the much smaller species of Odontoschisma (<<1 mm wide) or its brethren, Mylia taylorii. The latter species has leaves wider than long with rounded leaf tips topped by bright yellow-red gemmae, while those of M. anomala are longer than wide, with somewhat pointed leaf tips topped by light green gemmae.

+Distinguishing Features +

+

Running a gamut of colours from dark green to bright yellows and radiant reds, the wide-spreading leafy shoots (up to 5 mm wide) of Mylia taylorii are a common sight on decaying organic matter in high-precipitation regions. The simple round leaves appear in nearly an opposite arrangement, evenly spaced down the shoot but tightly converging near the tip so as to appear like a set of nested lips. Asexual reproductive bodies ("gemmae") are frequent and brightly coloured yellow and red, while underleaves are simple and elongate.

+

+Similar species +

+

In the pantheon of unlobed leafy liverworts, M. taylorii is distinguished from species of Cryptocolea, Syzygiella, Jungermannia and Solenostoma by its prominent underleaf, a feature absent or minute in those genera. Gyrothyra underwoodiana has the same widespreading and subopposite leave arrangement, but its underleaf is two-lobed and the undersides of the stem have recurrent purple patches in contrast to the to M. taylorii where such patches are absent and the underleaves are unlobed. Odontoschisma species can have a similair leaf form and arrangement, but they are usually less than 1 mm wide and 1 cm long and the leaves themselves are very concave. M. taylorii is a much bigger plant and its leaves are plane, not concave. Nardia has shoots that can show the nested lip arrangement of rounded leaves seen in M. taylorii, but it never has gemmae and its underleaf, while similair in shape, is attached to the base of the lateral leaves. In M. taylorii, the underleaves are free from the lateral leaves and gemmae are very common. Mylia taylorii has leaves wider than long with rounded leaf tips topped by bright yellow-red gemmae, while those of M. anomala are longer than wide, with somewhat pointed leaf tips topped by light green gemmae.

+Habitat +

+

+Distinguishing Features +

+

Running the gamut of reds, browns, yellows and greens, the small (< 1 cm tall by ~ 1 mm wide), upright shoots of O. denudata are a constant companion of decaying organic matter in very wet forests and bogs. The erect shoots with two rows of round, concave and unlobed leaves converging towards a shoot tip typically bedazzled with bright yellow or red gemmae is unique amongst regional leafy liverworts. Up close, you should also be able to make out a simple, round underleaf similair in size and shape to the lateral leaves.

+

+Similar species +

+

Unlobed leaves in nearly opposite arrangement are found in Jungermannia, Solenostoma, Cryptocolea, Nardia and Mylia, all of which can occur in similar habitats. Of these genera, only Nardia has an underleaf as in O. denudata, but if the former the underleaf is small and narrow, whilst in the latter it is large and round. O. elongatum has a similair leaf arrangement, but the plant is darkly pigmented and lacks gemmae atop its reclined shoots in contrast to the bright hues, erect shoots and apical gemmae of O. denudatum. O. sphagnicola is very similar but lacks gemmae and has pale thread like branches that emerge from the stem that are absent in O. denudatum. Arctic-alpine O. macounii occurs in very different habitat and lacks the pigmentation of O. denudatum.

+

+Habitat +

+

Moist to mesic humus, decayed wood, cliffs, crevices, ledges, peatlands, bogs, tundra, and occasionally tree bases in the lowland, montane, subalpine, and alpine zones

+Distinguishing Features +

+

Common in rare habitat, Odontoschisma elongatum presents itself on inorganic creek banks of very wet, boggy regions as a dark green-brown, reclined shoot of intermediate size (~2 mm wide by 1-3 cm long). The rounded, saucer-shaped leaves are arranged suboppositely and point towards the shoot tip. Underleaves are small, triangular and relatively inconspiculous.

+

+Similar species +

+

Could be mistaken for Syzygiella autumnalis, which occurs in the same habitat but has flat leaves and lacks an underleaf. Other round-leafed species of Odontoschisma are upright and have larger underleaves (O. macounii) or more colourful pigmentation (O. denudata), whereas O. elongatum as reclined shoots with dark pigmentation and barely perceptable underleaves.

+

+Habitat +

+

Moist to mesic humus, cliffs, ledges, crevices, peatlands, swamps, bogs, streambanks, waterfall spray zones, and tundra in the lowland, montane, and subalpine zones.

+Distinguishing Features +

+

Scarcely seen in the rare boggy habitat in which it occurs, O. fluitans is a stringy plant with dark green-to-brown shoots up to 2 mm wide. Up close, you should be able to make out distantly-spaced leaves with two equal, round-tipped lobes and shoots often interrupted by narrow, leafless and pale branches (see image). Hand lens inspection should turn up a few underleaves.

+

+Similar species +

+

With distant, round-lobed and dark green-to-brown leaves in boggy habitats, this species could only be confused with the very similar Gymnocolea inflata. That species, however, produces neither the leafless branches nor underleaves so prominent in O. fluitans.

+

+Habitat +

+

Wet depressions in bogs and peatlands, often submerged in shallow water, in the lowland, montane, subalpine, and alpine zones

Restricted to high latitudes and altitudes, the erect yellow shoots of Odontoschisma macounii stand to about 1 cm tall with leaves that spread out from the stem near to a 90 degree angle. The lateral leaves are unlobed, but it is the similarity in shape and size of the underleaves (see photo) that makes this species distinct in the genus.

+Distinguishing Features +

+

On account of its large size (leafy shoots can be >5 mm wide and longer than 5 cm), prominent teeth on large, deep green leaves bearing a conspicuous basal pleat, the common Plagiochila porelloides is perhaps the most moss-like of our regional liverworts, growing as it often does in relatively large clumps. Close inspection should show a stem devoid of underleaves and hairs, with large unlobed and asymmetrical lateral leaves alternating along the stem, their bases of attachment running down along the length of the stem ("decurrent, see photo). The leaves are often wide-spreading and the teeth are quite variable in number and size.

Plagiochila semidecurrens is an uncommon plant of very wet habitats, where its horizontal stems are laden with drooping, roundly folded and very toothy leaves that are shiny when dry. The spine-like teeth are unique for the genus on account of their number (many!) and length (up to 6 cells long).

+

Slender, thread-like, sparingly branched, yellowish-brown to olive-green shoots, often in loose mats, with strongly concave, deeply bilobed (0.3-0.5x length), slightly asymmetric leaves with acute lobes. Shoot tips often narrow and attenuate. Gemmae occasionally present (reddish-brown to green) in clusters at tips of attenuate shoots

+

+Similar species +

+

Similar to several other species/genera with thread-like shoots and concave, bilobed leaves. Under a microscope, it can be immediately separated from all of these by the uniformly thick cell walls and, especially, the concentric rows of quadrate to rectangular cells emanating from the leaf lobe tips (other species with irregularly placed, usually rounded cells). Macroscopically, it may be confused with Barbilophozia sudetica, but is distinguished by the placement of leaves around the stem rather than often primarily on one side (i.e., secund). Differs from Sphenolobus saxicola, a rare species of far northwestern BC, in its smaller size (shoots 0.4-1.5 mm wide, vs. 1.2-3 mm wide in S. saxicola), slightly smaller leaves (0.4-0.7 mm, vs. 0.5-0.8 mm in S. saxicola), and occasional presence of gemmae (always lacking in S. saxicola). Anastrophyllum assimile is also similar to S. minutum, but is a darker blackish to blackish-brown colour and the dorsal lobe of the leaves is slightly decurrent along the stem.

+

+Habitat +

+

Wide variety of wet to mesic, open to shaded habitats, but most frequent on acidic rocks, cliffs, and ledges; also terrestrial in subalpine heath, on peaty slopes, or on hummocks in bogs. Occasionally on decaying wood or tree bases.
