Leaves crisped when dry, erect-spreading when moist, lanceolate, distinctly high-sheathing at base; central lamellae in 20–30 longitudinal rows, 2–4 cells high; median leaf cells oval, rounded quadrate, 10–17 µm wide, thick-walled, usually bistratose; cells at sheathing base unistratose, narrowly rectangular, 15–30 µm × 5–9 µm, hyaline, thin-walled; margins single- or double-toothed, teeth small and obtuse; costa broad, reaching to the apex, grossly dentate on the back above. Dioicous. Perichaetial leaves 1.2–1.5 cm long. Setae straight, 3–5 cm long, rigid, reddish brown; capsules oblate-ovoid, with ring-like keeled under the mouth, clearly dorsal-ventral sided, usually horizontal; peristome teeth lacking; stomata at base of urns, surrounding by a circle of large cells; opercula conic, with hooked beaks.
