Plants medium-sized, in mats, olivaceous above, orange-brown, reddish brown or brown below; corticolous. Primary stem to 70 mm long, branching regularly, frequently tomentose; rhizoids smooth to weakly papillose, orange or reddish brown; secondary stem to 30 mm tall, branching by subperigonial and subperichaetial innovations; in section inner cortex 5-9 cells across, incrassate, outer cortical cells smaller, in 1-3 rows, consisting of stereids, outer surface occasionally rough. Stem leaves generally crowded; ovate-lanceolate to lanceolate, 0.5-1.5(-l.8) mm long; apex acute to acuminate; margins slightly decurrent; costa aristate, awn (120-)180-400(-460) µm long. Branch leaves crowded, ± equal in size, appressed and twisted to spirally twisted around stem when dry, erect-spreading to squarrose when wet, rugose; oblong, (1.0-)1.3-2.5 mm long; ventral surface keeled; apex acute, subacute or rounded-obtuse; margins plane or reflexed on one side below, entire, weakly prorate or crenulate above. Costa mucronate to cuspidate; in section subround, lamina ventrally inserted, 2 ventral cells larger, consisting of stereids, dorsal surface prorate. Upper laminal cells rounded-hexagonal to rounded or oval, incrassate, ± flat, 5-12 µm, smooth; basal cells rhomboidal to rectangular, incrassate, strongly pitted, infrequently papillose. Dioicous. Perigonia terminal, leaves ovate. Perichaetia terminal, frequently overgrown by subperichaetial innovations; leaves broadly oblong, oblong-lanceolate or lanceolate, 1.8-2.8 mm long. Seta 3-9 mm long, yellowish brown or reddish brown. Capsule oblong-cylindrical, yellowish brown, reddish brown or red brown, ribbed, urn 1.0-1.5 mm long, neck 0.5 mm long; exothecial cells irregular in shape, incrassate, smaller towards mouth, 2-4 rows at mouth transversely elongated. Peristome double; exostome teeth 16, revolute dry, linear, consisting of 2 divisions, 280-410 µm long, yellow-brown, densely striolate-papillose; endostome segments 16-32, outer surface smooth, inner surface vertically striate-papillose, yellowish or hyaline. Operculum 1 mm long. Calyptra 2.0-3.5 mm long, yellow-brown, reddish brown or brown. Spores 20-32 µm, granulate; isosporous.
