Monoicous. Perichaetial leaves rather large, erect, oblong-ovate at base, acuminate above. Setae 1.5–5.0 mm long; capsules ovoid to oblong-ovoid, symmetrical, brown; annuli narrow, well developed; opercula conical with beaks; exostome teeth light yellow, narrowly lanceolate, papillose, perforate; endostome segments reduced; basal membrane very low.
