Plants small to rather large, 1–3(–5) cm high, deep green to yellowish green, in slightly silky, dense tufts. Stems erect or ascending, simple or sparsely branched, densely foliate above, radiculose below; central strand present. Leaves distinctly deciduous in sections, flexuose or falcate-secund when dry, erect-spreading when moist, linear-lanceolate, 2.5–5.0(–8.0) mm long, gradually tapered from an oblong-ovate, not clearly sheathing base to a long, setaceous, semi-canaliculate acumen; margins plane or slightly incurved above, entire below or serrulate in the upper half or only at the apex; costa pellucid, poorly delimited at leaf base, occupying 1/3–1/2 the leaf base width, long-excurrent, smooth at back; upper cells long-rectangular, linear near the apex; lower cells rectangular, 18–30 µm × 4–8 µm, firm-walled, becoming shorter and narrower towards the margins, not forming clear marginal bands; alar cells forming somewhat auriculate base, short-rectangular to quadrate, inflated, hyaline or sometimes reddish brown. Dioicous. Setae flexuose when dry, cygneous when moist, 5–10 mm long, yellowish; capsules suberect to slightly inclined, cylindric, 1.0–1.2 mm × 0.5–0.6 mm, yellowish brown; opercula long-rostrate, slightly shorter than the urns; annuli absent; peristome teeth lanceolate, ca. 0.2 mm long, divided about to the middle, vertically striate and reddish.
