Stems simple or forked, loosely to densely foliate, sparsely radiculose at base. Leaves erect and slightly to strongly contorted when dry, erect- or flexuose-spreading when moist, usually acuminate from an elliptic base, sometimes hair-pointed, rarely blunt, sometimes bearing propagula on the costa, margins, or lamina; margins ± recurved, entire to serrate above, usually bordered; costa usually excurrent, with a single stereid band; cells smooth, thin-walled, laxly oblong-hexagonal above, rectangular below. Setae short; capsules immersed or emergent, erect and symmetric, oblong-cylindric; annulus deciduous as separate cells; operculum high-conic; peristome consisting of a low, tesselated membrane and 32 filiform, papillose, spirally twisted divisions.
