Branch leaves much smaller, narrower. Specialized asexual reproduction absent. Sexual condition dioicous; inner perichaetial leaves oblong-lanceolate, apex filiform-acuminate. [Seta reddish brown. Capsule inclined to horizontal, ovoid to cylindric, straight or weakly curved, not or weakly contracted below mouth; annulus little differentiated; operculum conic, sometimes short-rostrate; peristome double; exostome teeth with external surface transversely smooth to striolate proximally, papillose distally; endostome basal membrane 1/2 exostome teeth length, segments keeled, cilia 2–4.
