Plants minute to small, bulbiform, solitary, light green; terricolous. Stems to 1 mm high, simple; in section round, central strand small, inner cortical cells in 2 rows, large, thin-walled, outer cortical cells in single row, small, incrassate, reddish brown, epidermal cells larger, thin-walled. Leaves larger above, erect-spreading wet, little altered dry, lower leaves obovate-apiculate, to 1.5 mm long; upper leaves oblong-obovate, acuminate, 1.5-3.0 mm long; margins plane, entire below, bluntly serrate above. Costa ending below apex in lower leaves to short-excurrent in upper leaves; in section rounded, with a large central stereid band 2-4 cells thick and enclosing 1-2 larger, irregular cells or gaps, ventral cells in single row, large, firm-walled, dorsal surface cells similar to ventral cells, thickened. Upper laminal cells rhomboidal to oblong-rhomboidal, thin-walled; upper marginal cells narrower, long-rectangular, but not forming distinct border, upper ends projecting as marginal teeth; basal cells lax, rectangular. Autoicous. Perigonial branch short, at base of main stem, gemmate. Perichaetia terminal, leaves large, conspicuous, strongly concave, completely enclosing capsule. Seta short, erect, 0.7-1.0 mm long, yellowish; capsule broadly pyriform, cleistocarpic, pendent because of cygneous neck, 1.0-1.3 mm long, yellowish brown; exothecial cells quadrate to rectangular or occasionally rhomboidal, thin-walled; stomata present on neck, phaneropore; calyptra small, narrowly campanulate, 0.6 mm long, smooth; spores subreniform, 25-35 µm, yellowish, irregularly papillose.
