Plants minute, bulbiform, scattered, yellow-green; terricolous. Stems to 1 mm tall, unbranched; in section round, central strand very small, weak, cortical cells lax. Leaves crowded, appressed dry or wet, concave; suborbicular to oval, 0.6-0.8 mm long; apex apiculate, subcucullate; base scarcely differentiated; margins erect, entire or irregularly notched above. Costa percurrent to mucronate; ventral surface bearing numerous filaments, dorsal superficial cells rectangular, smooth; in section oval, guide cells 4, ventral filaments to 8 cells high, fused at base, apical cells of filaments conical, smooth, dorsal stereid band 4 cells thick, dorsal surface cells undifferentiated. Upper laminal cells rounded, quadrate to short-rectangular, weakly thickened, smooth; basal cells weakly differentiated, rectangular, hyaline, thin-walled. Dioicous or cladautoicous. Perichaetia terminal, leaves to 1 mm long. Seta 2.5-3.5 mm long, yellow; capsule elliptical, long, dark red to yellowish red; peristome with basal membrane projecting above capsule mouth, to 50 µm high, teeth short, irregularly cleft, 200-300 µm high, straight, strongly papillose; operculum conic to rostrate, 0.2-0.5 mm long, cells weakly twisted counter-clockwise; spores subround, 16-23 µm, essentially smooth.
