Setae 1.0–1.5 mm long, sometimes slightly scabrose; capsules nearly immersed to emergent, erect, ovoid; opercula conic, obliquely rostrate; annuli differentiated, in 2–3 rows of small, thick-walled cells; peristome double; exostome teeth lanceolate, thick, lamellate, finely papillose; endostome segments linear-lanceolate, nearly as long as the teeth, perforate; basal membrane low; cilia rudimentary.
