Plants in dense mats, light green to yellowish, glossy. Stems to 2 cm, 0.5–1 mm wide across leafy stem, prostrate to erect, ± complanate-foliate. Leaves erect-spreading, basally imbricate, ovate-lanceolate, symmetric, concave, 0.7–1.5 × 0.2–0.5 mm; margins plane or narrowly recurved nearly to apex, entire at apex or sometimes with few serrulations; apex acuminate, not abruptly contracted; costa ending just beyond leaf base, often ecostate; alar cells rectangular, 26–72 × 12–19 µm, in 1–5 vertical rows, terminating in 1 cell at base, region triangular; medial laminal cells 52–150 × 4–10 µm. Specialized asexual reproduction usually present as propagula, 57–108 × 7–14 µm, of 3–6 cells borne in leaf axils, or in clusters without stalks on abaxial leaf surface, or sometimes at leaf apices. Sexual condition dioicous, rarely fruiting. Seta light brown to orange-brown, 0.6–1 cm, straight. Capsule erect or rarely inclined, light brown to orange-brown when mature, straight or rarely somewhat arcuate, 0.5–1.2 × 0.2–0.6 mm, smooth, slightly wrinkled at neck when dry; operculum conic-apiculate to short-rostrate, 0.4–0.6 mm; endostome cilia absent, or 1 or 2, rudimentary. Spores 9–13 µm.
