Perichaetial leaves larger than stem leaves, with areolation laxer and costa more slender. Setae variable in length; capsules erect to nodding, symmetric to somewhat asymmetric, globose to subglobose, irregularly wrinkled to furrowed when dry; operculum conic-rostrate, the beak straight or obhque; peristome, if present, consisting of 16 linear-lanceolate teeth connivent at the tips, smooth or faintly papillose below.
