May sometimes have dorsal lobe apices that are sporadically acute or even sometimes acuminate. These specimens are otherwise identical to specimens with rounded apices. Distinguishing from Frullania franciscana: Ocelli sometimes scattered on the dorsal lobe (cf. Distinguishing from Frullania nisquallensis: ventral leaf margins plane or nearly so
Frullania chilcootiensis
Frullania franciscana		ID notes from BFNA treatment: has variable dorsal lobe apices that are usually rounded, but may sometimes be bluntly acute. Distinguishing from Frullania californiana: ocelli arranged in a median line that is 1--2, sometimes 3 cells wide for F. franciscana, versus ocelli sometimes scattered on the dorsal lobe Distinguishing from Frullania nisquallensis: In F. nisquallensis the ocelli are frequently absent, although they may be present in a few dorsal lobes as a short, broken line. The ventral leaf margins of F. franciscana usually have a blunt angulation on one or both sides at about the middle of the leaf.

Orthotrichaceae ( 20 species)

Scientific Name	Common Name	Summary
Lewinskya speciosa		Worley's map shows collections from the northern mainland. From BFNA "The ribbed capsule, large size, and more slender leaf apices distinguish it."
Orthotrichum anomalum		Worley reports this as primarily an interior species, with the only coastal record from Skagway.
Orthotrichum columbicum		Recently (re)separated from Orthotrichum consimile (see paper linked below in references). Calyptra naked (separating from O. consimile) and exostome not reddish (separating from O. pulchellum)
Orthotrichum consimile		Recent paper (see link below) indicates this species may occur in the region, but Orthotrichum columbicum is likely much more frequent. Hairy calyptra distinguishes this species from Orthotrichum columbicum
Orthotrichum cupulatum		Reported from limestone outrcrop on Kuiu Island. Has been considered rare in Alaska and BC, where it is primarily known from the interior (Worley notes)
Orthotrichum lyellii		Collections noted by Worley all from far northern mainland. Has been found on non-native landscaping trees in Sitka.
Orthotrichum obtusifolium		Worley reported as known only from Skagway.
Orthotrichum pulchellum		Scattered collected noted by Worley from across much of the region. Separated from Orthotrichum consimile and Orthotrichum columbicum by reddish exostome. From BFNA account: "Distinguished from all species of Ulota by the glabrous calyptra and immersed stomates, and from O. consimile by the 16, reddish exostome teeth that are papillose-reticulate with slender, high papillae, and by the stomates that are always located at or beyond the middle of the capsule. Also, O. pulchellum has plants that are rarely longer than 1 cm and the capsules are usually just barely exserted and oblong-cylindric."
Orthotrichum rupestre		Worley reports this has been found at Lake Lindeman, BC - and has more of a continental distribution.
Ulota barclayi		Worley shows collections span the region. BFNA indicates leaves should be much less twisty than other species in the area. Also leaves at base of sporophyte will be different than the rest of its leaves, and exostome teeth are reflexed.
Ulota crispa		BFNA indicate this species is restricted to east of the Mississippi River in NA, see http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=200001670 However, a 2016 publication Integrative taxonomy sheds light on an old problem: the Ulota crispa complex (Orthotrichaceae, Musci) has this species in western North America. The range map included shows Washington and southern BC, but it may be worth considering it as a possibility in this region See also Ulota intermedia
Ulota curvifolia		Worley notes only reports are from Skagway and Lake Lindeman. Grows on rock (may be more likely to be found at higher elevations - if it occurs in the region beyond where it's been reported).
Ulota drummondii		Worley shows records from outer islands and near Juneau, and reports its generally on alder in this region. Capsule more football shaped should be distinct.
Ulota intermedia		Part of the U. crispa complex which BFNA indicates is restricted to east of the Mississippi River in NA, see http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=200001670 (though Worley reported it from Southeast Alaska - see Ulota crispa) However, a 2016 publication Integrative taxonomy sheds light on an old problem: the Ulota crispa complex (Orthotrichaceae, Musci) has this species in western North America. The range map included shows U. intermedia the only one in the complex currently known/expected from Southeast Alaska.
Ulota megalospora		A few collections were noted by Worley, who thought it probably occurred throughout the region. Creeping stems with erect branches should be distinct in this genus in the region (though consider Ulota reptans)
Ulota obtusiuscula		Common throughout the region. BFNA notes this species has consistently contorted and twisted leaves, even when wet.
Ulota phyllantha		Common maritime species. Dark brown 'brood-bodies' at the end of leaves are usually present and distinctive for this species.
Ulota reptans		BFNA doesn't indicate this species is currently known from NA, see http://www.efloras.org/florataxon.aspx?flora_id=50&taxon_id=250062028
Zygodon reinwardtii		Worley reports an old record from southern tip of Prince of Wales Island as the only one in the region.
Zygodon viridissimus		BFNA does not include Alaska in the range of this species, though Worley indicates a handful of records from as far north as Sitka (while noting it is increasingly rare at the northern end of its range).

Sphagnaceae ( 43 species)

Scientific Name	Common Name	Summary
Sphagnum alaskense
Sphagnum andersonianum		Andrus indicates this species is probably not common in Southeast Alaska.
Sphagnum angustifolium		Andrus indicates this species is common in Southeast Alaska.
Sphagnum aongstroemii		Andrus indicates this species is in Southeast, though it's not clear how common. Rock ledges are a common habitat.
Sphagnum austinii		Andrus says this species is common on hummock tops in Southeast Alaska. Worley treated S. imbricatum, but according to the FNA entry on Sphagnum imbricatum, it is primarily an Asian species with a single collection from Northwestern Alaska. S. austinii seems like the most likely option for collections previously identified as S. imbricatum.
Sphagnum balticum		Andrus indicates this species is uncommon in Southeast Alaska and probably not the same as the balticum in the arctic-subarctic.
Sphagnum bartlettianum		Andrus describes the abundance as scatterred in Southeast Alaska.
Sphagnum brevifolium		Andrus indicates this species probably widespread but not common in Southeast Alaska.
Sphagnum capillifolium
Sphagnum centrale		BFNA indicates this species does not occur in Alaska. Possibly collections are in fact Sphagnum alaskense?
Sphagnum compactum		Andrus says Fairly Common in Southeast Alaska.
Sphagnum divinum		Formerly S. magellanicum https://www.tandfonline.com/doi/abs/10.1080/03736687.2018.1474424?scroll=top&needAccess=true&journalCode=yjbr20
Sphagnum fimbriatum		Andrus indicates this species is common in Southeast Alaska.
Sphagnum fuscum

Sphagnum mendocinum		Andrus indicates this species is common in Southeast Alaska.
Sphagnum obtusum		Andrus indicates this species is common near Yakutat.
Sphagnum pacificum		Andrus indicates this species is very common in Southeast Alaska.
Sphagnum palustre		Status of this species is unclear. Included in Worley as occuring in the Sitka area, but BFNA Account for Sphagnum palustre does not have it occuring in Alaska.
Sphagnum papillosum
Sphagnum platyphyllum		Not in BFNA, recently described? Andrus indicates this species is not common in Southeast Alaska.
Sphagnum pseudopapillosum		Apparently not in BFNA. Andrus says: "pseudopapillosum"- an as yet undescribed but common species. grows around bases of hummocks and in dense carpet patches in blanket mires. Looks rather like compactum. Common on Sitka.
Sphagnum quinquefarium
Sphagnum riparium
Sphagnum rubellum
Sphagnum rubiginosum		Andrus indicates this species is common, especially in forests in Southeast Alaska.
Sphagnum russowii		Andrus indicates this species is common in Southeast Alaska.
Sphagnum sitchense		Type specimen was collected on Harbor Mountain
Sphagnum sjorsianum		Andrus says this recently described species is uncommon and known from only Juneau and Ketchikan so far.
Sphagnum squarrosum
Sphagnum subfulvum		Andrus indicates this species is scattered and rare in Southeast Alaska.
Sphagnum subnitens		Andrus described the abundance as "Scattered"
Sphagnum subsecundum		Andrus says: "per Jon Shaw, a different species separate from subsecundum in Eastern NA but call it this for now. maybe common"
