Leaves of nearly uniform size, grooved at the costa and broadly channeled to keeled, ovate- to oblong-lanceolate, usually oblong-sheathing at base; margins entire or dentate, thickened in the upper 1/3-2/3, narrowly recurved in the lower 3/4; costa percurrent to short-excurrent as a mucro, covered ventrally by quadrate to rectangular, papillose cells and dorsally by smooth, rectangular cells, in section semicircular to reniform, with the ventral stereid band usually small and the dorsal band well-differentiated, with 2-5 guide cells in addition to hydroids; upper cells mostly homogeneous in size and shape, subquadrate to short-rectangular, up to 2:1, plane at the surface, with walls evenly thickened and papillae solid or hollow, flat, crowded, 2-6 per lumen, granulose to compound; basal cells differentiated across the leaf, rectangular, smooth or weakly papillose. Dioicous. Inflorescences terminal. Perichaetial leaves elongate and sheathing. Setae elongate; capsules long-cylindric; annulus of 1-3 layers of vesiculose cells; operculum long-conic; peristome consisting of 32 red, densely spiculose divisions, twisted 1-2.5 times above a short, tesselated membrane. Calyptrae cucullate.
The genus is more thoroughly treated by Zander (1978g).
