general taxon notes:
The genus consists of some eight species in the world (Hofmann 1998; Crosby et al. 2000). Two species are recognized here. The Chinese records of Homalothecium sericeum (Hedw.) Schimp. as reported by Redfearn et al. (1996) cannot be verified at this time.

Leaves erect-appressed or imbricate, sometimes secund when dry, mostly narrowly ovate-lanceolate to lanceolate, slenderly or shortly acuminate, usually 2–4-plicate; margins entire or serrulate throughout; costae extending to ca. 2/3 the leaf length; median leaf cells linear-rhomboidal or linear, smooth or sometimes slightly prorate; basal cells shorter, broader, yellowish, pitted; alar cells in a very small group, quadrate or shortly rectangular. Dioicous. Perichaetial leaves triangularly lanceolate. Setae elongate, reddish or yellowish brown, more or less roughened, twisted when dry; capsules erect, symmetric, or inclined, curved, elongate-ovoid or cylindrical; opercula obliquely long conic-rostrate; annuli developed; exostome teeth narrowly lanceolate, cross-striolate at base, bordered, trabeculate at dorsal surface; endostome segments keeled, perforate; basal membrane low or moderately high; cilia present, nodulose, or absent.
