Plants small to medium-sized to rather robust, 10–30(–50) mm, sometimes to 70 mm high, in loose tufts. Stems erect, forked or aggregately-branched; central strand absent. Leaves distantly arranged, contorted-curved when dry, erect-spreading or reflexed when moist, oblong-elliptic to oblong ovate-lanceolate, abruptly acute at the apex; margins entire, weakly recurved in the lower half, plane, serrulate in the upper half; costa stout, subpercurrent; upper leaf cells quadrate to hexagonal or rounded-hexagonal, thin- or thick-walled, multi-papillose; basal cells larger, smooth, yellowish or hyaline. Dioicous. Perichaetial leaves rather larger, sheathing at the base. Setae elongate, slender, sometimes aggregated; capsules cylindrical, erect or curved; annuli differentiated, consisting of several rows of cells, deciduous; peristome teeth linear-lanceolate, deeply divided, papillose or obliquely striate, basal membrane absent, rarely with properistome; opercula conic-rostrate, with long-beak.
