Plants yellowish green to brown; terricolous. Stems up to 5 mm tall, branching by sub-perichaetial innovations; rhizoids reddish brown, smooth; in section with cortical cells thin-walled, epidermis not differentiated. Leaves larger above, crisped when dry, erect to erect-spreading when wet, reflexed; linear-lanceolate, 1.0-1.8 mm long; keeled; apex acuminate or occasionally acute; base scarcely differentiated, ± sheathing in upper leaves; margins plane or frequently recurved on one side below, entire to crenulate at apex, frequently flexuose above. Costa ending below apex to subpercurrent, ventral superficial cells rectangular, dorsal superficial cells linear; in section crescent-shaped to subround, ventral surface flat, lamina ventrally inserted, guide cells in 1 layer, ventral stereid band absent, ventral surface cells incrassate, bulging, dorsal stereid band small, dorsal surface cells incrassate, bulging. Upper laminal cells rounded-quadrate or rounded-hexagonal, incrassate, bulging, 8.7-16.3 µm, smooth, in (4)5-7(8) rows on each side of costa at leaf middle, in 3-5(6) rows just below apex; basal cells occasionally reaching higher along costa, rectangular, thin-walled, smooth. Autoicous. Perigonia terminal on short branches, inner leaves ovate. Perichaetia terminal, leaves scarcely differentiated. Seta 1.8-2.4 mm long, yellowish to brown, twisted anticlockwise above. Capsule exserted, ovoid, 0.7 mm long, yellowish to brownish, weakly 8-ribbed, neck short, mouth orange; exothecial cells irregular rectangular, thin-walled, smaller above, 2-4 rows at mouth transversely elongated, cells of ribs weakly differentiated, bulging; stomata on neck, few, phaneropore. Peristome single, inserted below mouth, teeth 16, distant, filiform, 93-110 µm long, orange, smooth, basal membrane low. Operculum 0.5 mm long. Calyptra not seen. Spores 11-15 µm.
