Plants medium-sized to large, dark green or yellowish green, slightly glossy, in loose mats. Primary stems creeping, naked or often covered with a few small stipe leaves, rhizoids sparse; secondary stems loosely or densely pinnately or irregularly pinnately branched, often erect or dendroid, rarely with pendent flagelliform branches; pseudoparaphyllia none. Leaves in 8-rows, loosely appressed, narrowed from a widely ovate base to a broadly lingulate, often apiculate, or rounded-obtuse to nearly truncate apex, sometimes undulate; margins usually serrulate above; costae single, rigid, ending in the upper parts of leaves to leaf apex; upper leaf cells rounded-quadrate or oblong-rhombic; median and basal cells elongate, narrowly rhomboidal, thick-walled; alar cells not differentiated. Dioicous or autoicous. Perichaetial leaves smaller than vegetative ones, sheathing at the base, gradually narrowed toward the apex. Setae short, smooth; capsules ovoid, slightly exserted; opercula conic, obliquely rostrate; annuli not differentiated; peristome double; exostome teeth narrowly lanceolate, roughened or finely papillose; endostome segments nearly as long as the teeth, perforate, densely papillose; basal membrane low; cilia none. Calyptrae cucullate, sparsely hairy. Spores spherical or nearly so, roughened or papillose.
