Capsules horizontal to pendent, ovoid to subglobose, rugose or furrowed when dry; opercula plano-convex; peristome double, exostome teeth narrowly triangular, reddish orange, finely papillose below, coarsely papillose near tips, dorsal trabeculae faint, ventral trabeculae strongly thickened, endostome segments broad, nearly as long as the exostome, yellow to reddish yellow, papillose, segments split along the median line and each half diverging toward the cilia and sometimes uniting with the next one-half segment over, cilia rudimentary or well developed, 1–3, often fused.
