Plants small, only up to 1 cm high, reddish brown or green, in low dense cushions. Stems sparsely branched, without central strand in cross section. Leaves erect, imbricate when dry, spreading when moist, small, keeled above, 1.4–1.7 mm long, lanceolate from a narrowly ovate base, gradually narrowed toward apex, ending in a denticulate to spinulose hyaline hair-point; margins entire, recurved on one or both sides, bistratose above; costa prominent, ending below apex, dorsally smooth or nearly so, with homogeneous cells in cross section; upper cells unistratose except at margins, irregularly quadrate, 4–6 µm wide, with thick and somewhat sinuose walls; median cells short-rectangular, 7–11 µm × 5–7 µm, with sinuose walls; basal marginal cells quadrate to short-rectangular, somewhat transparent, with transverse walls thicker than longitudinal walls; basal juxtacostal cells rectangular, with smooth or lightly sinuose walls. Autoicous. Perichaetial leaves much larger than vegetative leaves, ending in a long, spinulose to denticulate, hyaline hair-point. Setae much shorter than capsules, only ca. 0.2–0.3 mm long; capsules small, erect, immersed, ovoid, ca. 1.0 mm long, reddish brown, smooth; exothecial cells oblate, with rather thin walls; stomata present at base of the urns; annuli absent; opercula with straight or slightly oblique beaks; peristome teeth lanceolate, yellowish brown to reddish brown, strongly perforate above, outer surface densely papillose above, sparsely papillose in somewhat vertical rows below, inner surface papillose throughout. Calyptrae small, mitrate. Spores 9–11 µm in diameter, yellowish, nearly smooth.
