Plants small to medium-sized, caespitose, yellowish green or olivaceous above, yellowish brown or brown-green below; corticolous. Stems 8-26 mm tall, scarcely tomentose below; in section subround to subpentagonal, central strand absent, inner cortex 11-14 cells across, thin-walled to incrassate, outer cortical cells smaller, in 1-4 rows, incrassate to stereids, epidermis not differentiated, outer surface rough. Leaves ± crowded, erect when dry, spreading when wet; ovate-lanceolate to lanceolate, 2.4-3.7(-4.3) mm long; ventral surface keeled; apex narrowly acuminate to subulate, 0.1-0.4 (-0.7) mm long, cells rounded to elongate; margins incurved, entire; unistratose. Costa weak above, extending into acumen; ventral and dorsal superficial cells rounded above, linear below, flat to bulging, smooth to weakly papillose; in section crescent-shaped to subround, bulging dorsally, cells scarcely differentiated, incrassate. Upper laminal cells rounded-hexagonal to oval, incrassate, slightly bulging, 10.0-18.7(-33.0) pm long, papillae low, blunt, 1-3 over lumen, simple or forked; basal cells smooth or papillose, rectangular, quadrate towards margin, generally thin-walled. Gonioautoicous. Perigonial leaves ovate. Perichaetia terminal; leaves narrowly oblong or lanceolate, 2.0-3.6 mm long, apex acuminate to subulate, 0.2-0.6(-1.0) mm long, costa extending into acumen. Seta short, (0.3-)0.5-0.8(-1.3) mm long. Capsule immersed to emergent, oblong-cylindrical, 1.9-2.3(-3.0) mm long, 8-ribbed, neck differentiated; exothecial cells rectangular, longitudinal walls incrassate, shorter at mouth; stomata at base of urn and on neck, phaneropore. Peristome double; exostome teeth in 8 pairs, triangular, 160-275 µm long, densely papillose; basal membrane absent, processes 8, alternating with teeth pairs, 175-240 µm long, 2 cells wide, coarsely papillose, cell divisions prominent below. Operculum 0.3 mm long, conic-apiculate, yellowish with red or red-brown rim. Calyptra 2.5-3.0 mm long; hairs ascending, multi-to uniseriate, crenulate to denticulate, smooth to papillose. Spores 16-25 µm, papillose.
