Plants small, caespitose, yellowish green or olivaceous above, brownish below; corticolous. Stem up to 15 mm tall, tomentose below; rhizoids reddish brown, smooth; in section with inner cortex 5-15 cells across, thin-walled to incrassate, outer cortical cells smaller, in 1-3(4) rows, incrassate or consisting of substereids or stereids. Leaves ± crowded, larger above, crispate dry, erect-spreading to widespreading wet, unistratose; oblong to oblong-lingulate, 1.8-3.0 mm long; ventral surface keeled; apex acute or occasionally acuminate or cuspidate; base occasionally sheathing; margins plane to recurved below, entire. Costa ending below apex, percurrent or infrequently mucronate; in section round, bulging dorsally, ventrally flat, laminal insertion ventral, ventral stereid band absent, 2-4 ventral cells larger, dorsal stereids or substereids present. Upper laminal cells rounded-hexagonal, incrassate, essentially flat, 11-19 µm, smooth; basal cells rectangular, thin-walled to incrassate, infrequently papillose. Autoicous. Perigonia lateral, gemmate, leaves ovate. Perichaetia terminal, frequently overgrown by subperichaetial innovations; inner leaves hyaline, erect, enveloping capsule, broadly oblong, concave, apex rounded, margin plane, entire below, toothed at apex, costa ending below apex, upper laminal cells rhomboidal, hyaline, thin-walled. Seta very short. Capsule cylindrical, 1-2 mm long, abruptly narrowed to a short neck, ribbed; exothecial cells rectangular to quadrate, thin-walled to incrassate, smaller at mouth; stomata present at base of urn. Peristome double; teeth 16, in 8 pairs, triangular, 240-300 µm long, brownish or yellowish, minutely papillose to striolate-papillose; endostome processes narrow, keeled, alternating with teeth pairs, shorter than teeth, minutely striolate-papillose, pale yellow, basal membrane absent. Operculum short-conical. Calyptra 0.8-1.0 mm long, hairs ascending, uniseriate, smooth. Spores 12-22 µm.
