Dioicous. Perichaetial leaves larger, costa long-excurrent from a subulate acumen. Setae straight, 4–5 mm long, reddish brown; capsules short-cylindric, 0.3–0.4 mm × 0.2 mm, erect, symmetric or nearly so, smooth when dry; opercula stoutly rostrate, nearly as long as the urns or slightly shorter; annuli absent; peristome teeth lanceolate, ca. 350 µm long, slightly spreading when dry, divided about 1/3–1/2 down to the base.
