红叶藓属
Plants rather robust, yellowish green when young, reddish brown to reddish when old, gregarious or loosely caespitose. Stems simple or branched, densely foliate; central strand usually present. Leaves appressed, curved-contorted or crisped when dry, erect-spreading or reflexed when moist, oblong-ovate to oblong-elliptic, narrowly lanceolate, or ligulate, gradually acute to broadly acute at the apex; margins plane or recurved below mid-leaf, usually irregularly dentate above the mid-leaf, often with 3–4 rows of marginal cells reddish brown, pellucid, with fewer papillae, thus showing a distinct differentiated border; costa strong, attenuate near the tips, ending at the apex or shortly excurrent, in cross section two stereid bands present; median and upper leaf cells green, rounded-quadrate or irregularly rounded-hexagonal, with numerous round or C-shaped or satellite papillae; basal cells elongate, irregularly rectangular, smooth, hyaline, often reddish. Gemmae frequently present in leaf axils or on rhizoids. Dioicous or sometimes monoicous. Perichaetial leaves differentiated, usually sheathing in the lower half. Setae elongate, twisted or straight, purple when old; capsules short-cylindric, yellowish brown, reddish when old; annuli differentiated, of 1–2 rows of vesiculose cells; peristome teeth filiform, erect or twisted, densely papillose, sometimes with rudimentary teeth; opercula obliquely rostrate. Calyptrae cucullate. Spores spherical, light brown, finely papillose.
The genus consists of some twenty-seven species in the world. Nine species and one variety are recognized for China.
