Plants medium-sized to large, coarse, in loose or dense wefts or mats, yellow-green, grayish green, blackish or reddish brown, olive brown, or opaque gray, dull, sometimes hoary with shining hairs distally. Stems creeping, remotely foliate, secondary stems creeping, erect-ascending, or loosely spreading, closely foliate, sparingly and irregularly branched to subpinnate, stoloniform or flagelliform-tapered, radiculose; sclerodermis cells in 2 or 3 rows, small, walls thick, cortical cells enlarged, central strand absent; paraphyllia absent; pseudoparaphyllia foliose, papillose. Stem and branch leaves erect to secund when dry, spreading when moist, ovate, broadly oblong- ovate, or ovate-lanceolate, strongly concave; base narrowing to insertion, broadly decurrent to abruptly concave-auriculate; margins erect, incurved, or revolute on one or both sides, mostly entire, denticulate to irregularly spinose-serrate at apex; apex acute, acuminate, or piliferous, concolorous, hyaline-white, or hyaline with pellucid tips, flat to subtubular, epilose, terminating in sharp or truncate point, or capillary hair; ecostate; alar cells differentiated, small or somewhat enlarged, often smooth, becoming papillose distally, walls thin or thick and porose, region in several marginal rows or in excavate auricles; laminal cells 1-stratose, papillose on both surfaces, walls usually thick, coarsely porose-sinuose; laminal cells near insertion short-rectangular, often smooth; mid basal cells concolorous to pigmented, papillae simple; medial and distal cells subquadrate, short-rectangular, or oblong-rhombic, 1-2(-3):1, 1- or multipapillose over lumina and/or walls, papillae simple or multifid; apical cells chlorophyllose or echlorophyllose, smooth to papillose, walls thick, even to strongly porose. Specialized asexual reproduction absent. Sexual condition autoicous or paroicous [rarely synoicous]; perigonia axillary on secondary stems and branches, gemmate; perichaetia terminal on main stems and branches, often appearing lateral by innovation, leaves erect, similar to vegetative leaves or larger, longer, ovate to narrowly ovate- lanceolate, margins entire, not to conspicuously ciliate, cilia sparse mid leaf, dense in apex, often longer than leaf length, hyaline. Vaginula with paraphyses few or many, long-filiform, yellow- hyaline. Seta single, very short or to beyond perichaetial leaves, straight, slender to stout, smooth, usually with sclerotic swelling below capsule neck. Capsule stegocarpous, erect, immersed to exserted, subglobose, obovoid, ovoid-cylindric, ellipsoid, fusiform, pyriform, or obpyriform, symmetric, contracted at base and below mouth, neck short, irregularly longitudinally sulcate when dry, mouth rigid, smooth, incurved, wide or narrow; stomata in neck, cryptoporic or phaneroporic; annulus absent; operculum planoconvex, sometimes subumbonate-apiculate, or 83 conic and rostrate; peristome absent. Calyptra conic-mitrate or cucullate, undivided at base or with several lobes, smooth, naked or pilose. Spores irregularly spheroid, flattened, with obscure triradiate mark on one side, brown.
