Autoicous. Perichaetial leaves not differentiated. Setae erect, 4–6 mm long; capsules long exserted, cylindrical, ca. 1.8 mm long, slightly constricted below the mouth when dry, 8-ribbed along the entire length, with an indistinct neck; exothecial cells clearly differentiated into longitudinal bands; stomata superficial; opercula shortly rostrate; peristome double; exostome teeth 16, united in 8 pairs, lanceolate, often reflexed when dry, densely papillose throughout; endostome segments 16, linear-lanceolate, hyaline or pale yellow, smooth on the outer surface, finely papillose on the inner surface.
