Plants medium-sized to large, in loose mats. Stems creeping, sympodial, stoloniferous; secondary stems ascending, irregularly branched, branches few to many, curved or in whorls; paraphyllia absent; radiculose on primary stems. Leaves crowded, imbricate when dry, spreading when moist, ovate, ovate-lanceolate, or cordate-ovate; margins entire, serrate, or serrulate; apex acuminate or acute; ecostate or costa double or more [single], short; alar cells differentiated, many; laminal cells ovate to elliptic, smooth, rarely singly papillose, or occasionally prorate, walls thick; basal cells longer. Sexual condition dioicous; perigonia axillary or borne on secondary stems or branches, deltoid-apiculate or gemmiform; perichaetia borne on main stem or lateral branches. Seta short to elongate. Capsule erect, immersed to exserted, smooth; annulus present or sometimes absent; operculum conic or oblique-rostrate; peristome double; exostome teeth 16, pale; endostome basal membrane low or absent, segments absent, weakly developed, or rarely well developed, cilia absent. Calyptra cucullate, naked or hairy. Spores anisosporous, occasionally large, papillose. SELECTED REFERENCE Manuel, M. G. 1974.
