Plants small to medium-sized, caespitose, green or yellowish green or rarely reddish green above, brownish or occasionally reddish brown below; terricolous or saxicolous. Stems 1-7(-15) mm tall, simple or branching by innovations, occasionally tomentose below; rhizoids yellowish brown to reddish brown, papillose, tubers abundant, (180-)230-300(-450) µm, yellowish brown to brown. Leaves evenly spaced along stem or crowded above, larger above, spirally twisted around stem when dry, erect and slightly bent towards direction of twisting when wet; ovate to oblong or occasionally obovate-spathulate; (0.8-)1.0-1.6 mm long; apex acute to obtuse; margins plane above, plane to recurved below, entire to denticulate above; border generally inconspicuous, occasionally absent, cells in 1-2(-3) rows, sinuate. Costa cuspidate to aristate, awn (0.2-)0.4-0.6(-0.7) mm long, generally smooth, mostly yellowish, infrequently reddish below; in section subround to round, laminal insertion ventral, ventral surface cells differentiated, dorsal stereid band strong, stereids in 2-4 rows, dorsal surface cells incrassate, hydroids present between stereid band and guide cells. Upper laminal cells rhomboidal to hexagonal, thin-walled, (26-)35-50(-63) µm long, (12-)15-19(-23) µm wide; basal cells quadrate to rectangular, infrequently pitted, infrequently reddish below. Filamentous gemmae absent. Dioicous or synoicous. Perichaetia terminal, leaves narrowly lanceolate. Seta 15-25 mm long, yellowish above, reddish below; capsule pendulous, yellowish or brown, cylindrical to pyriform, urn 1.0-1.5 mm long, contracted below mouth when dry, neck wrinkled when dry, 0.9-1.4 mm long; exothecial cells irregularly rectangular, incrassate, smaller at mouth; peristome double, exostome teeth oblong-acuminate, finely papillose, endostome segments tapered above, broadly perforated, cilia 2-3, appendiculate, basal membrane high, minutely papillose; operculum conic, apiculate; calyptra not seen; spores small, 11-15 µm, pale yellow, smooth to granulose.
