Stem leaves ascending or imbricate, elongate-ovate, ovate, or nearly round, slightly concave, obtuse at apex; costae single, extending well beyond mid-leaf or nearly to leaf apex; median leaf cells linear; sometimes with short, hyaline, thin-walled (initial) cells near leaf apices, often with rhizoids densely distributed at the dorsal side; alar cells hyaline, large, inflated, usually auriculate. Autoicous or dioicous. Inner perichaetial leaves lanceolate, costae single. Setae slender, curved when dry, reddish or purple; capsules ascending or horizontal, elongate-ovoid or cylindrical, usually arcuate, mouth constricted when dry; annuli often absent or indistinctly differentiated; cilia 2–3, nodulose.
