general taxon notes:
The genus Macromitrium consists of some 260 species in the world (Crosby et al. 2000). In Asia, there are about 120 species according to various authors (Eddy 1996; Gangulee 1976; Noguchi 1967, 1972; Noguchi & Iwatsuki 1989; O’Shea 2002; Tan & Iwatsuki 1991, 1993; Vitt et al. 1995). Some 41 species of Macromitrium were listed for China by Redfearn et al. (1996). Seventeen species and one variety are recognized by this study. The Chinese record of M. ousiense Broth. & Paris cannot be confirmed at this time.

4. Macromitrium Brid.  蓑藓属   suo xian shu
Muscol. Recent. 4: 132. 1819 [1818].
 
Plants medium-sized to rather large, dark green, yellowish brown or reddish brown, in large flattened mats. Stems elongate, prostrate, irregularly or freely branched, with erect or creeping, short or elongate branches; branches simple or forked; rhizoids numerous, red. Leaves often variously contorted to crisped or squarrose, occasionally erect, appressed when dry, plicate, erect-spreading or squarrosely-recurved when moist, often lanceolate, oblong- to ovate-lanceolate or lingulate, sometimes linear to linear-lanceolate or funiculate, acuminate, acute, apiculate, or blunt to obtuse; costae single, stout, subpercurrent to percurrent, or shortly excurrent to long hair-pointed; upper leaf cells rounded-quadrate or rounded-hexagonal, often papillose, rarely smooth; basal cells rectangular to linear, thick-walled, smooth or papillose on the side walls; basal juxtacostal cells often thin-walled, lax, hyaline; sometimes basal cells shorter. Autoicous or dioicous. Perichaetial leaves similar to or larger than the vegetative ones. Setae elongate, rarely very short, smooth or sometimes roughened; capsules exserted, subglobose to elongate-ovoid, or shortly cylindrical, smooth or more or less plicate, sometimes puckered at the mouth; stomata present; opercula conic, often slenderly long-rostrate; annuli not or weakly differentiated; peristome double or single, rarely absent. Calyptrae mitrate or cucullate, plicate, naked or hairy, splitting or lobed at the base. Spores spherical, papillose.
