Dioicous. Perichaetial leaves shortly ovate-lanceolate. Setae reddish brown, 5–13 mm long; capsules cylindrical, erect, symmetrical; opercula conic, shortly obliquely beaked; annuli well differentiated; peristome double; exostome teeth lanceolate, papillose at base, hyaline above; endostome very reduced or rudimentary; basal membrane very low or absent; cilia absent.
