general taxon notes:
There are about 6 species of Pseudoleskeella in the world, and three species are known in China. Potier de la Varde (1937) first reported Pseudoleskeella catenulata (Brid. ex Schrad.) Kindb. from Xinjiang. C. Gao (1977) reported P. catenulata and P. tectorum (Brid.) Kindb. from northeastern China.

Gen. Eur. N.- Amer. Bryin. 20. 1897.
 
Plants slender, soft or rigid and fragile, dark green to brown, dull to slightly shiny. Stems thin, prostrate, regularly or irregularly pinnately branched; paraphyllia linear to lanceolate. Stem leaves imbricate when dry, spreading when moist, cordate, slightly decurrent at base, suddenly narrowed to a long acuminate apex; basal margins entire, plane or recurved, plicate below; costa single, up to middle of the leaf or unequally forked, sometimes very short or absent; upper and median leaf cells round or rhomboidal; basal cells near margins flatly quadrate, slightly thick-walled; branch leaves rather small, acuminate. Dioicous. Inner perichaetial leaves pale green, moderately sheathing at base, gradually narrowed to an acuminate apex; costa short or absent. Setae elongate, slender; capsules patent, oblong-cylindrical, curved, reddish brown, contracted at lower part of capsule mouth when dry; annuli differentiated; peristome double; exostome teeth narrowly lanceolate, yellowish, borders differentiated, densely transversely striate and lamellate on outer surfaces; endostome segments pale yellow, finely papillose, nearly as long as the teeth, thin, keeled; basal membrane high; two cilia present, shorter than teeth, sometimes rudimentary or absent; opercula conic, obliquely beaked. Spores small, yellowish green to green, nearly smooth.
