Plants medium-sized, mixed with other bryophytes, olivaceous or yellowish green above, greenish brown to brown below; corticolous. Stems 10-15 mm tall; in section subpentagonal to subround, central strand absent, inner cortex 12-14 cells across, incrassate, outer cortical cells smaller, in 2-4 rows, sub-stereids to stereids, epidermis not differentiated, outer surface rough. Leaves ± crowded, erect when dry, spreading when wet; unistratose; ovate-lanceolate, 2.5-4.0 mm long; ventral surface keeled; apex narrowly acuminate to aristate, 0.3-0.6 mm long; margins recurved for lower ± three-quarters, plane above, entire to crenulate, unistratose. Costa extending into arista; superficial cells rounded to oval above, linear below, ± flat, smooth; in section crescentshaped to subround, bulging dorsally, cells scarcely differentiated, incrassate. Upper laminal cells shortly rounded-rhomboidal, oval or irregular in shape, flat to weakly bulging, (10.0-)15.0-27.5(-35.0) µm long, 7.5-13.8 µm wide, smooth to papillose, papillae low, blunt, mostly simple; basal cells yellowish to yellowish brown below, walls papillose, frequently pitted, rhomboidal to rectangular, quadrate at margin, incrassate. Gonioautoicous. Perigonial leaves ovate. Perichaetia terminal; leaves ovate-lanceolate or lanceolate, apex aristate to subulate, inner leaves smaller. Seta short, 0.8-1.5 mm long. Capsule immersed to emergent, ovate-cylindrical, 1.5-2.2 mm long, 8-ribbed in upper half when dry, neck weakly differentiated; exothecial cells irregularly rectangular, thin-walled to incrassate, smaller at mouth, incrassate; stomata phaneropore, on urn. Peristome double; exostome teeth in 8 pairs, reflexed when dry, cleft down middle, triangular, 280-330 µm long, yellowish brown, minutely striolate-papillose; basal membrane absent, processes 8, alternating with tooth pairs, broad, stout, oblong-lanceolate or triangular, blunt, 2 cells wide, dividing lines conspicuous, papillose with ridges along walls. Operculum conic-apiculate, 0.4 mm long. Calyptra 2.2-3.0 mm long, weakly plicate, hairy. Spores 25-34 (-53) µm, papillose.
