Dioicous. Inner perichaetial leaves sheathing at the base, long acuminate at the apex. Setae 1.0–1.5 cm long; capsules erect or horizontal, ovoid or oblong-ovoid, symmetrical or asymmetrical, with slender apophyses; opercula conic, obliquely shortly rostrate; annuli distinctly differentiated; peristome double; exostome teeth lanceolate, yellow, striolate on outer surface, densely trabeculate on inner surface; endostome segments lanceolate, shorter than or as long as the teeth, yellow or hyaline at the tips, finely papillose, rarely smooth; basal membrane high, cilia somewhat developed.
