Plants minute, gregarious, green; terricolous. Stems to 0.5 mm tall; in section central cells very thin-walled, cortical cells lax. Leaves imbricate dry, patent wet; broadly ovate to oval, 0.8-1.8 mm long; apex obtuse to rounded, mucronate to apiculate; margins revolute above base, entire. Costa short-excurrent, smooth; ventral superficial cells quadrate to short-rectangular, papillose, dorsal superficial cells rectangular, smooth; in section round, guide cells 2, small, ventral surface cells similar to lamina cells, papillose, dorsal stereid band 2-4 cells thick, dorsal surface cells substereids, sometimes lateral cells larger, papillose. Upper laminal cells quadrate to hexagonal, some short-rectangular, papillose, 2-4 C-shaped papillae over lumen; basal cells larger, rectangular to quadrate, smooth. Autoicous. Antheridia axillary on upper stem; perichaetia terminal, leaves undifferentiated. Seta 2.0-3.5 mm long, yellowish; capsule cylindrical to oval, 1.0-1.2 mm long; peristome rudimentary, exserted above mouth, light yellow, faintly papillose; operculum short-conic; calyptra cucullate, to 1-2 mm long; spores irregular, rounded to triangular, 17-22 µm, weakly verruculate.
