Plants small, forming groups, green to yellow-green; terricolous. Stems 3-5 mm long, simple; in section round, central strand present, inner cortical cells large, outer cortical cells in 2 rows, smaller, strongly incrassate. Leaves larger above, equally spaced, curved and weakly contorted dry, erect-spreading wet; ligulate or asymmetrically ovate-elliptical, 0.8-1.2 mm long; apex broadly acute to obtuse, cuspidate; margins limbate on vaginant laminae, crenulate by projecting cells on other laminae, limbidia narrow, ending above insertion, marginal throughout; costa strong, short-excurrent. Vaginant laminae ± equal, to 3/4 of leaf length; dorsal lamina tapering proximally to insertion. Laminal cells quadrate to hexagonal, 5-7 µm long, superficially bulging, cells sharply mammillose, rarely with 3-4 low, sharp papillae over lumen. Autoicous. Perigonia gemmate, axillary. Perichaetia terminal; leaves somewhat larger, little differentiated. Seta 2-4 mm long, yellowish; capsule erect to inclined, urn short, cylindrical to elliptical, 0.5-1.0 mm long, yellowish, mouth reddish; exothecial cells quadrate, strongly thickened in corners; peristome cleft above, teeth 0.3 mm long, yellowish red; operculum conical, to 0.7 mm long; spores round, 12-15 µm, granulate.
