Perigonia relatively large, terminal on very short branches, or sessile, somewhat below the perichaetia. Perichaetial leaves up to 5 mm long, sheathing at the base. Setae 2–5 mm long, yellowish, thick; capsules erect, shortly obovoid, slightly asymmetric; annuli in 2–3 rows of cells, persistent; opercula stoutly short-rostrate; peristome teeth reddish brown, wide-spreading when dry, irregularly divided halfway down or less, sometimes undivided and perforate near the middle, vertically striate near to the tips.
