Autoicous or dioicous. Perichaetial leaves sheathing at base, abruptly subulate above. Setae single or clustered, short to elongate, straight, terminal, usually becoming lateral because of innovations; capsules erect, ovoid-cylindric; opercula long-rostrate; annuli none or present; peristome teeth irregularly divided, papillose.
