Autoicous. Perichaetial leaves slightly differentiated, somewhat smaller than upper stem leaves. Setae reddish brown, 4–6 mm long, erect, slightly twisted above when dry; capsules cylindrical, base broader, somewhat enlarged distally, 4–5 mm long, with dark red, longitudinal ribs; peristome single, 16 teeth, ca. 330 µm long, orange, erect to inflexed, regularly lanceolate to truncate, papillose; preperistome present, smooth; annuli absent; opercula with a long, straight beak.
