Plants small, slender to robust, soft or rigid, yellowish green, yellowish brown, or brown, more or less glossy, in loose mats. Primary stems creeping; secondary stems loose or dense, pendulous or erect-patent above, irregularly or irregularly pinnately branched; branches usually short, sometimes long, often curved, densely foliate, obtuse or attenuate at the apex. Secondary stem leaves triangularly ovate-lanceolate, oblong-ovate-lanceolate, or broadly ovate-lanceolate, squarrose or widely spreading above, clasping at the base, gradually or rather abruptly narrowed to a short or long acumen; margins often rugose above, serrulate to serrate; costae single, slender, reaching mid-leaf or above; leaf cells linear-rhomboidal or linear, thin-walled to moderately thick-walled, usually unipapillose, sometimes with 2–3 papillae in each cell; basal juxtacostal cells shorter and broader, thick-walled, often porose, not papillose; alar cells shorter, not clearly differentiated; branch leaves similar to stem leaves, sometimes plicate; axillary hairs mostly consisting of 5 short, basal cells and 3 long upper cells. Dioicous. Perichaetia on branches; inner perichaetial leaves narrowly oblong-lanceolate. Setae short, smooth; capsules ovoid or oblong-ovoid, brown, smooth, erect; opercula conic at the base, erectly or obliquely rostrate; annuli more or less differentiated; peristome double; exostome teeth narrowly lanceolate, papillose above, cross-striolate below; endostome segments linear, keeled, papillose; basal membrane low to moderately high; cilia rudimentary or absent. Calyptrae small, cucullate or mitrate, lobed at the base, smooth or hairy. Spores spherical, finely papillose.
