general taxon notes:
Brotherus (1925) recognized four species of Myurella in the world. P.-C. Chen et al. (1978) reported 3 species: M. julacea (Schwaegr.) B. S. G., M. tenerrima (Brid.) Lindb., and M. sibirica (C. Müll.) Reim. with 2 synonyms: M. sinensi-julacea C. Müll. = M. julacea (Schwaegr.) B. S. G. and M. gracilis Lindb. = M. sibirica (C. Müll.) Reim. from China. Recently, J.-X. Lou and P.-C. Wu (1980) published M. brevicosta J.-X. Lou & P.-C. Wu [= Glossadelphus prostratus (Dozy & Molk.) Fleisch.] from Xizang. Three species are recognized here for China.

Plants slender, in cushions or loosely caespitose, green or dark green. Stems creeping, densely inclined or erect, irregularly branched, forkedly branched or caespitosely branched; often with bundles of rhizoids; branches obtuse at apex, often flagellate; paraphyllia absent. Leaves rounded ovate, imbricately arranged, abruptly acute, acuminate or rounded at apex; leaf margins incurved, entire or irregularly serrate; costa single, forked or absent; leaf cells minute, slightly thick-walled, inconspicuously pitted, rounded or rhomboidal, basal cells rectangular or quadrate. Dioicous. Inner perichaetial leaves reddish brown, lanceolate, acuminate above, margin plane, serrate; costae absent; cells rhomboidal. Setae 1–2 cm long; capsules ovoid or shortly cylindrical, yellowish brown, erect, curved after spores disposal; annuli differentiated; exostome teeth lanceolate, yellow or lightly yellowish, hyaline at the apex, keeled, with zig-zag median line, lamellae conspicuous on inner surfaces; endostome segments linear-lanceolate, finely papillose, nearly as long as the teeth; basal membrane high; cilia short or elongate, but shorter than segments; opercula conic, with a short beak.
