Plants small, hyaline above, yellow-green below; terricolous. Stems 0.1-0.2 mm tall; in section without central strand, cortical cells lax, marginal cells reddish brown. Leaves imbricate with contorted awns wet or dry, concave; broadly oval to obovate, 1.0-1.5 mm long; apex acute, frequently hyaline; margins revolute above base, entire to denticulate. Costa excurrent as long, smooth, hyaline awn, 0.5-0.8 mm in upper leaves; ventral superficial cells lax, bulging, quadrate to short-rectangular, with 1-2 weak papillae, dorsal superficial cells elongate, smooth; in section round, guide cells indistinct, ventral surface cells enlarged, swollen, 4-6 cells in single row, papillose, dorsal stereid band 5-6 cells thick, some cells substereids, dorsa surface cells undifferentiated. Upper laminal cells quadrate, incrassate, smooth; median leaf cells quadrate to hexagonal, finely papillose, with 1-3 C-or O-shaped papillae over dorsal lumen; basal cells larger, short-rectangular. Paroicous. Perichaetial leaves broader; margins reflexed to revolute; apical cells smooth, rhomboidal, hyaline, thin-walled. Seta to 0.3 mm long; capsule cleistocarpic, globose-apiculate, 0.9-1.0 mm long, reddish yellow; exothecial cells short-rectangular to quadrate; calyptra minute, mitrate, 0.4 mm long; spores round, 22-25 µm, granulate.
