general taxon notes:
Entodontopsis consists of 17 species worldwide (Crosby et al. 2000), mostly from tropical or subtropical regions growing on rocks, tree trunks, or rotten wood. Buck and Ireland (1985) separated Entodontopsis from Stereophyllum Mitt. based on the length and width of leaf cells, with Entodontopsis having cells much longer than wide and Stereophyllum having cells nearly as long as wide. All species of Stereophyllum previously reported from China have leaf cells significantly longer than wide; therefore, they are treated under Entodontopsis.
 
The first species of Stereophyllum from China, S.setschwanicum, was described by Brotherus (1924). Iwatsuki (1964) reported S. ligulatum A. Jaeger from Taiwan, and P.-C. Chen et al. (1978) recorded S. anceps (Bosch & Sande Lac.) Broth. from Hainan. Redfearn et al. (1996) listed six species of Entodontopsis from China. Stereophyllum tavoyense (Hook. ex Harv.) A. Jaeger reported from Yunnan by P.-C. Wu (1992) is proved to be E. anceps. Five species are recognized here from China.

1. Entodontopsis Broth.   拟绢藓属   ni juan xian shu
Nat. Pflanzenfam. I(3): 895. 1907.
 
Plants small to medium-sized, pale green or yellowish green, glossy, in loose or dense mats. Stems prostrate, 1–3 cm long, complanate or julaceous, simple or irregularly, remotely branched; in cross section cortical cells thick-walled; central strand weakly differentiated; rhizoids often densely located on ventral surface of stems; pseudoparaphyllia few, filamentous. Stem and branch leaves similar, densely or loosely arranged, symmetric or asymmetric, erect-spreading when moist, imbricate when dry, slightly falcate, sometimes secund, elliptical-lanceolate, narrowly ovate or ovate-lanceolate, sometimes ligulate, acuminate, abruptly acute or obtusely apiculate at apex, not decurrent at base; margins plane or slightly involute, entire or serrulate above; costae single, reaching 1/3–1/2 the leaf length; median leaf cells narrowly rhombic to rhomboidal, thin-walled, not porose, usually smooth, rarely prorate; alar cells distinctly differentiated, consisting of several rows of quadrate or shortly rectangular cells, uneven in numbers on both sides of angle. Autoicous. Perigonial leaves obtuse at apex, costae absent. Perichaetial leaves bluntly acuminate, entire or serrulate, costate or ecostate. Setae straight or twisted, yellowish or yellowish brown, smooth; capsules erect or slightly curved, cylindrical, ellipsoidal or ovoid, constricted below the mouth when dry; annuli deciduous, 2–3 rows; opercula conic, shortly rostrate; peristome double; exostome teeth indistinctly bordered, cross-striolate below, papillose above; endostome segments keeled, perforate, smooth or papillose; basal membrane low or high; cilia often reduced or rarely 1–3. Calyptrae cucullate, smooth. Spores spherical, papillose.
