Plants small and slender, 0.5–1.0 cm high, olive-green to dark green, in dense tufts or cushions. Stems usually rope-like, sparsely branched, with well developed central strand in cross section. Leaves spirally imbricate or curved when dry, erect-spreading when moist, 1.0–2.0 mm long, narrowly ovate-lanceolate, strongly keeled above, tapering to acute at apex, ending in long, smooth to slightly roughened, often decurrent, hyaline hair-points, up to 2/3 the laminal length; margins usually revolute on one side; costa percurrent, smooth on the back, with nearly undifferentiated ventral and dorsal cells and a few small median cells in cross section; upper and median leaf cells bistratose at least at margins, oblately short-rectangular to rounded-quadrate, 6–8 µm wide, with strongly incrassate to somewhat sinuose walls; basal marginal cells short-rectangular, 15–30 µm × 7–10 µm, hyaline, thin-walled; basal juxtacostal cells elongate-rectangular, 25–50 µm × 7–10 µm, strongly incrassate and sinuose. Dioicous. Perichaetial leaves larger than vegetative leaves, with long, hyaline hair-points, up to or nearly as long as the laminal length. Sporophytes not seen.
