Plants medium-sized to large, forming mats, olivaceous or yellowish green to green above, orange-brown or reddish brown to brown below; corticolous. Primary stem up to 70 mm long, branching regularly, tomentose; rhizoids smooth to weakly papillose, orange-brown to brown; secondary stem up to 38 mm tall, branching by subperichaetial innovations; in section inner cortex 5-8 cells across, incrassate, outer cortical cells smaller, in 2-4 rows consisting of stereids. Stem leaves crowded; ovate to ovate-lanceolate, 0.6-1.3 mm long; apex acute or acuminate; margins decurrent; costa ending below apex, extending into acumen or short-excurrent, awn up to 220 µm long. Branch leaves crowded, ± equal in size, appressed and twisted to spirally twisted around stem when dry, erect-spreading to wide-spreading when wet, rugose; oblong to oblong-lanceolate, 1.5-2.8 mm long; ventral surface keeled; apex acute, subacute or cuspidate; margins plane, occasionally reflexed on one side below, entire. Costa ending below apex or extending into cuspidate point; in section subround, lamina ventrally inserted, cells not differentiated or 2 ventral cells larger, consisting of stereids, dorsal surface smooth to rough. Upper laminal cells rounded-hexagonal to rounded, incrassate, ± flat, 8-13 µm, smooth; basal cells rhomboidal to rectangular, incrassate, strongly pitted. Pseudautoicous; dwarf male plant axillary on secondary stem, branching by subperigonial innovations. Perichaetia terminal, frequently overgrown by subperichaetial innovations; leaves oblong-lanceolate or lanceolate, 2.3-3.0 mm long, apex acuminate or cuspidate, costa ending below apex to cuspidate. Seta 3-5 mm long, yellowish brown or red-brown. Capsule ovoid or oblong-cylindrical, red-brown to brown, smooth to weakly ribbed; urn 1.3-1.8 mm long; neck 0.2-0.5 mm long, wrinkled dry; exothecial cells irregular in shape, incrassate, smaller at mouth. Peristome double; exostome teeth 16, revolute dry, linear, consisting of 2 divisions, 400-470 µm long, brown, densely striolate-papillose; endostome segments 16-32, outer surface smooth, inner surface vertically striolate-papillose, yellowish. Operculum 1 mm long. Calyptra 3.0-3.5 mm long, yellowish brown or reddish brown. Spores 12-35 µm, granulate; anisosporous.
