Inner perichaetial leaves smaller or slightly larger than vegetative leaves, 2.0–2.25 mm long, gradually constricted into a narrow and long piliform apex, denticulate above. Setae elongate, smooth, up to 2 cm long; capsules ellipsoidal to cylindrical, less than 2 mm long; exothecial cells rectangular, vertical walls thinner or thicker; opercula long rostrate.
