Plants medium-sized, loosely caespitose or gregarious, green to yellow-green; corticolous. Stems 5-10 mm long, sparsely radiculose below; in section cortical cells in 4-6 rows. Leaves crowded and larger above, ± comose, spirally twisted around stem when dry, erect-spreading wet; oblong to elliptical or obovate, 1.5-2.2 mm long; apex obtuse, cuspidate; margins narrowly revolute from base to near apex, weakly serrate at apex. Costa short-excurrent; in section round, guide cells 2, small, ventral cells 2, in single layer, similar to guide cells, dorsal stereid band strong, 4 cells thick, with hydroids present below guide cells, dorsal surface cells similar to ventral surface cells, frequently thickened. Upper laminal cells mostly 2-3: 1, oblong-hexagonal, 37-50 µm long, 15-20 µm wide, thin-walled, weakly pitted; marginal cells elongate and thickened, in 2-3 rows forming weak border, generally not visible because of revolute margins; basal cells quadrate to rectangular, 1-2:1, thin-walled, faintly reddish. Perichaetial leaves triangular, smaller than vegetative leaves. Seta 20 mm long, reddish yellow; capsule erect, cylindrical-pyriform, 2.5-4.0 mm long, yellow-brown, mouth reddish, neck sulcate, 1.0-1.5 mm long; exothecial cells rectangular, weakly thickened, smaller at mouth; peristome teeth narrowly tri-angular, ±300 µm high; endostome with high basal membrane, segments absent; operculum conical; spores round, 25 µm, green, papillose.
