Leaves erect to spreading, divaricate or slightly falcate-secund, 2–3 mm long, suddenly narrowed from a broad, ovate sheathing base to a channeled, long subula; margins mostly entire, serrulate at the extreme apex; costa flat, filling 1/5–1/3 the leaf base width and almost the entire subula, in cross section with several separate substereid bundles in the center enclosed by a row of large, thin-walled, hyaline cells on both surfaces; laminal cells thin-walled, smooth, oblong-hexagonal at the shoulder, elongate-rectangular near the base, marginal cells narrower; alar cells not differentiated. Paroicous. Perichaetial leaves not much differentiated from the upper vegetative leaves. Setae elongate, cygneous when moist, flexuose when dry, ca. 6 mm long, smooth; capsules yellowish brown, oblong-elliptic, smooth; stomata absent; opercula with a long and erect beak; annuli not well developed; peristome teeth inserted below the mouth, divided halfway down, vertically striate below, papillose above.
