Stems creeping to ascending, 2–8 (–10) cm long, simple to irregularly branched, rarely ±pinnate, brown with reddish brown rhizoids on stem or abaxial costa insertion, rarely forming tomentum; pseudoparaphylia present, foliose. Leaves strongly falcate to circinate, narrow lanceolate to oblong-lanceolate, 2–4 mm long, 0.35–1.1 mm wide, plicate, ±concave, not or scarcely altered when dry; apices long-acuminate; costae subpercurrent or at least extending ¾ leaf length; margins entire near base or denticulate throughout, plane, without a border; laminal cells linear, 25–120 μm long, 4–8 μm wide, shorter and wider near base, smooth; alar cells hyaline, quadrate to rectangular, ±inflated, (7–) 14–30 μm long, 8–18 μm wide, forming a transversely triangular group of c. 8–10 cells which are bounded above by oblong to ±isodiametric cells which grade rapidly into laminal cells, reduced to 2–3 cells in extreme angles in branch leaves. Perichaetial leaves lanceolate, narrowing gradually to a long-acuminate apex, denticulate at margins. Setae 1–3 (–5) cm long, red-brown, smooth. Capsules suberect to pendent, cylindric, curved or straight, 1.5–3 mm long. Opercula conic or apiculate-conic, 0.4–0.6 mm long. Peristome double; endostome with well-developed cilia.
