Plants with dorsal, lateral, and ventral stem leaves often different in shape and size. Stem leaves straight to falcate, ovate-, oblong- or narrowly lanceolate; margins recurved at base, serrate or serrulate, rarely entire distally, entire proximally; costae double; median laminal cells linear, thin- to thick-walled, smooth, rarely porose; alar cells differentiated, subquadrate to rectangular. Branch leaves smaller and narrower than stem leaves. Sexual condition dioicous; inner perichaetial leaves oblong-lanceolate, filiform-acuminate, serrate, usually reflexed at apices. Seta long, smooth, usually sinistrosely twisted in proximal half and dextrorsely twisted distally when dry. Capsule inclined to horizontal, ovoid to cylindric; exothecial cells elongate-rectangular to subquadrate, rarely polygonal; operculum conic, sometimes with a short beak; peristome double, exostome teeth transversely smooth to striolate proximally, papillose distally on the external surface, papillose and with projecting trabeculae on the internal surface; segments of endostome teeth keeled, not split; cilia 2--4; basal membrane about 1/2 as high as exostome teeth. Spores finely papillose.

turgens (Müller Hal.)
Stem to 7 cm, densely pinnate-branched, rarely loosely branched; leafy stems complanate, with secund leaves, hypnaceous in appearance. Stem leaves well differentiated; dorsal leaves strongly falcate, narrowly lanceolate, gradually narrowed to a slender and long apex, subcordate at base, plicate, 2.7--2.9 x 0.60--0.75 mm; margins markedly recurved both at base of apex and below, irregularly serrulate above, subentire proximally; costae double and parallel, 1/4--1/3 the leaf length; median laminal cells linear, weakly flexuose, lumen 60--80 x 2--3 µm, thick-walled, porose, smooth; alar cells well-differentiated, 6--8 in marginal row, 8--10 in transverse row; ventral leaves flat at apices. Branch leaves narrower, 1.6--2 x 0.35--0.45 mm. Innner perichaetial leaves slightly reflexed at apices; costae double or indistinct; laminal cells thick-walled. [Seta 2.5--3 cm. Capsule horizontal, cylindric, weakly arched, 2.2--2.8 mm exclusive of the operculum, 0.9--1.2 mm wide; exothecial cells subquadrate, rarely polygonal, 17--48 x 17--27 µm, thick-walled. Spores 18--22 \um.]
Capsules mature fall. Boreal forest zone to arctic tundra, mostly growing on wet or moist rocks, often calcareous; 710--4730 m; B.C., Yukon; Alaska; Asia (China, Japan, Nepal, Russia).
