Stems prostrate, sometimes ascending, irregularly or pinnately branched; central strand developed or absent; leafy stems flattened or terete; pseudoparaphyllia lanceolate or ovate, rarely triangular. Stem leaves often differentiated into dorsal, ventral, and lateral ones; dorsal leaves erect or falcate-secund, ovate, elliptical or triangular to lanceolate, acute, shortly acuminate to long acuminate, slightly to distinctly decurrent at base, concave or flat; margins recurved at base, rarely recurved throughout, serrate or serrulate above, entire below, rarely nearly entire throughout; costae double, short to strong, separate or united at base; median leaf cells linear-rhomboidal, thin- to thick-walled, rarely porose; basal cells larger, thicker-walled, sometimes porose, rarely colored; alar cells differentiated, shortly rectangular or rounded hexagonal; lateral leaves falcate-secund, gradually acuminate; ventral leaves falcate-secund or coarse, broader, gradually acuminate, costae shorter; branch leaves smaller, narrower than stem leaves. Dioicous. Perichaetia and perigonia on main stems; perigonia rarely on branches. Perigonial leaves ovate-lanceolate, ecostate. Inner perichaetial leaves elliptic-lanceolate, slenderly acuminate, serrulate, often reflexed at apex, costae indistinct. Setae slender, smooth, often twisted when dry; capsules horizontal, with short necks, ovoid to cylindrical, slightly curved, smooth, constricted below the mouth when dry; opercula conic, shortly rostrate; peristome double, hypnoid; exostome teeth narrowly lanceolate, densely cross-striate below, papillose above on the outer surface, bordered, trabeculate on the inner surface; endostome segments pale yellow, papillose, keeled, often perforate; basal membrane high; cilia 2–4, hyaline, papillose, nodulose. Calyptrae cucullate. Spores yellowish brown, spherical, smooth or minutely papillose.
