general taxon notes:
The genus Homomallium is similar to Pylaisia Bruch & Schimp. and Platygyrium Schimp. in B.S.G., but differs in having shortly rhomboidal median leaf cells, quadrate or shortly rectangular alar cells grouped in numerous rows, and often horizontal capsules with perfect double peristome teeth and cilia. There are about 13 species of Homomallium in the world with 9 well understood species (Crosby et al. 2000). Seven species are recognized here for China.

11. Homomallium (Schimp.) Loesk.   毛灰藓属   mao hui xian shu
Hedwigia 46: 314. 1907. Hypnum subgen. Homomallium Schimp., Syn. Musc. Eur. 616. 1860.
 
Plants slender, soft, green or yellowish green, somewhat glossy, in flattened mats. Stems creeping, irregularly or subpinnately branched; branches short, ascending or curved, pseudoparaphyllia present. Leaves patent or secund, ovate- to oblong-lanceolate, concave; margins plane, entire or distinctly serrulate; costae double, short, weak or absent, sometimes single; leaf cells shortly rhomboidal, smooth or prorate; alar cells distinctly differentiated, small, mostly quadrate or sometimes shortly rectangular, numerous rows of cells extending along basal margins. Autoicous or dioicous. Inner perichaetial leaves erect, not plicate. Setae slender, reddish; capsules suberect to horizontal, oblong-ovoid, curved, contracted at mouth; opercula conic, shortly rostrate; annuli differentiated; peristome double; exostome lanceolate, furrowed, with zigzag median line, cross-striolate at base; trabeculate on ventral surfaces; endostome segments liner-lanceolate, perforate; basal membrane high; cilia 2–3, nodulose, papillose. Calyptrae cucullate. Spores spherical, reddish brown, minutely papillose.
