Plants fairly large, up to 7 cm high, brownish green or reddish brown, weakly shiny, in loose or dense tufts. Stems reddish brown, erect or ascending, densely foliate, often dichotomously branched. Leaves crispate when dry, erect-patent to falcate-secund when moist, lanceolate, contracted at base, gradually narrowed from an oblong, somewhat sheathing base to a long, canaliculate acumen; margins plane, entire below, sharply double-toothed above; costa slender, reddish brown, shortly excurrent, serrate at back above; upper cells short-rectangular, 10–18 µm × 8–9 µm, thick-walled, slightly porose, sometimes projecting on the dorsal surface; basal cells elongate, 60–85 µm × 8–12 µm, thick-walled, porose; alar cells bulging out of leaf base, inflated, reddish brown near the margins, hyaline within. Dioicous. Perichaetial leaves highly convolute-sheathing at base. Setae single, straight or slightly curved, up to 5 cm long; capsules short-cylindric, deep reddish brown, curved, ca. 5 mm × 1 mm; opercula obliquely long-rostrate; peristome teeth ca. 0.6 mm long, yellowish brown, not clearly divided, showing a fissure, papillose at the tips, without clear striolation at base. Spores 14–20 µm in diameter, yellowish brown, papillose.
