Plants medium-sized, in loose colonies, dark green and somewhat glossy; corticolous or saxicolous. Primary stems long-creeping; secondary stems erect, to 120 mm long, branching somewhat irregular above stipe; in section round, central strand absent, inner cortical cells thin-walled, hyaline, in 8-10 rows, outer cortical cells smaller, thick-walled, yellow-brown, in 8-12 rows. Leaves ± crowded, spreading wet, appressed dry; stem leaves ovate to ovate-elliptical, 1.5-3.0 mm long; apex acute or acuminate, apiculate on larger, broader leaves; narrowed to insertion; margins plane, denticulate; branch leaves ovate to elliptical, 1.0-1.5 mm long; acute; narrowed to insertion; margins plane, denticulate, cells not differentiated. Costa single, extending to midleaf or above, smooth, ending distally in short dorsal spine, ventral and dorsal surface smooth; in section elliptical, cells not strongly differentiated. Upper laminal cells rhombic to rhomboidal, homogeneous, 12-22 µm long, 5-6 µm wide, walls somewhat thickened, smooth; basal cells rectangular, 12-40 µm long, 5-6 µm wide, hyaline, walls thickened, smooth; alar cells not differentiated. Perigonia on stems and branches, gemmate; perigonial leaves ovate. Perichaetia along stem and branches, green; perichaetial leaves oblong-acuminate, 1.2-1.8 mm long. Seta 10-15 mm long, yellow-brown, smooth. Capsule exserted, erect, ellipsoid, 2.0-2.5 mm long, smooth, brown. Peristome double, brown; exostome teeth linear, papillose, 600-800 µm high; endostome segments linear above low basal membrane, as long as teeth, papillose, cilia absent. Operculum long-rostrate, 1.5 mm long. Calyptra cucullate, smooth or with a few hairs. Spores rounded, 12-15 µm, granulate, brown.
