Plants slender, creeping along substrate with pendent branches, green to yellow-green, dull; saxicolous or corticolous. Primary stems creeping; secondary stems pendent, to 400 mm long, branching irregular; in section round, central strand very small, inner cortical cells in 7 or 8 rows, weakly thickened, outer cortical cells in 4 or 5 rows smaller, thick-walled, yellow-green. Leaves erect-spreading wet, appressed dry; ovate to oval or oblong, (1.4-)1.7-2.0(-2.5) mm; abruptly long-acuminate, frequently extending out as a long smooth awn; cordate or ± subauriculate and decurrent at base; margins plane, entire. Costa ending in acumen, ventral and dorsal surfaces smooth; in section bulging dorsally, to 3 cells thick, guide cells not differentiated, dorsal surface cells thick-walled or not differentiated. Upper laminal cells elliptical to rounded rhombic, elongate-fusiform at apex, 10-12 µm long, walls weakly thickened, papillose; papillae small, scattered over lumen; apical and occasionally marginal cells smooth; basal cells quadrate to short rectangular, hyaline, smooth becoming elongate-fusiform, strongly thickened and pitted juxtacostally; alar cells small, quadrate. Dioicous. Perigonia on branches, gemmate. Perichaetia on distal branches; perichaetial leaves oblong, 2.2 mm long, leaf cells fusiform, thickened. Seta 2.5 mm long, brown; vaginula long with numerous long paraphyses reaching base of capsule. Capsule exserted, erect, ovoid, 1.5-2.0 mm long, smooth, green-brown to brown; exothecial cells quadrate to short rectangular, walls thin, cells at mouth slightly larger, darker; stomata numerous, phaneropore. Peristome yellow; exostome teeth lanceolate, papillose, perforated, 0.5 mm high; endostome segments linear above basal membrane, perforated, shorter than teeth, almost smooth; cilia absent. Operculum conic-rostrate, 1.0 mm long. Calyptra cucullate, 2 mm long, hairy. Spores rounded, 20-25 µm, papillose, green.
