general taxon notes:

 

The species of this family often occur in temperate regions of the world on tree trunks, rocks, or soil.
 
Six genera of the Entodontaceae, including Orthothecium Schimp. and Pterigynandrum Hedw., were treated in China by P.-C. Chen et al. (1978). The above-mentioned two genera were respectively transferred to the Hypnaceae by Crum and Anderson (1981) and to the Leskeaceae by Noguchi (1991), although Buck (1980) still placed Pterigynandrum under the Entodontaceae. Both genera are here excluded from the Entodontaceae. Sakuraia Broth. was reduced to synonymy of Entodon Müll. Hal. by Buck (1980) and Crosby and Magill (1981); however, Noguchi (1994) continued to recognize this genus with a single species, S. conchophylla (Cardot) Nog. We accept Noguchi’s treatment in recognizing Sakuraia. Five genera of the Entodontaceae are now found in China.

Entodontaceae
绢藓科   juan xian ke
by Hu Ren-liang and Wang You-fang
 
Plants small, medium-sized to rather robust, or sometimes slender, often green to yellowish green or golden, glossy, in dense mats. Stems prostrate, rarely ascending, regularly branched, densely foliate, complanate or julaceous; central strand present; paraphyllia and pseudoparaphyllia absent. Stem and branch leaves similar, rarely differentiated, sometimes dorsal and lateral leaves slightly differentiated, symmetric or somewhat asymmetric, plane or slightly to strongly concave, ovate, oblong-ovate, ovate-lanceolate, or slenderly lanceolate, obtuse, acute, or acuminate at apex; margins plane, entire or serrulate; costae double, short, sometimes indistinct or absent, rarely reaching to the mid-leaf; median leaf cells rhomboidal to linear, smooth; alar cells numerous, quadrate. Autoicous or dioicous. Male and female plants similar. Perigonia bud-like, small. Perichaetia on short branches. Setae 5–40 mm long, smooth; capsules erect, symmetric, sometimes slightly curved or asymmetric; opercula conic-rostrate, usually with a long beak; annuli developed or absent; peristome double or sometimes exostome reduced or absent; exostome teeth lanceolate or narrowly lanceolate, yellowish or reddish brown, inserted below the mouth, sometimes cross-striolate at base or papillose, rarely smooth, with median zigzag line; endostome segments linear; basal membrane usually not well developed; cilia rudimentary or absent. Calyptrae cucullate, smooth. Spores small, spherical, usually less than 55 µm in diameter, somewhat roughened to finely papillose.
