general taxon notes:
In the absence of multicellular spores germinating inside the capsules, the genus is hardly separated from Cryphaea. Five species are currently recognized in the world (Manuel 1977, 1981; P.-C. Rao 2000 [2001]). Three species are known in China.

Hedwigia 55: 282. 1914.
 
Plants slender, yellowish green to dark green, in patches. Stems erect or inclined, more or less pinnately branched. Stem and branch leaves similar, loosely imbricate when dry, spreading when moist, ovate to ovate-lanceolate, gradually to abruptly acuminate; margins entire, recurved below; costae reaching mid-leaf to apex; leaf cells oval to oblong-elliptical, thick-walled, smooth or prorate; basal juxtacostal cells elongate; alar cells quadrate. Autoicous. Inner perichaetial leaves broadly sheathing at the base, abruptly piliferous; costae excurrent. Setae very short; capsules immersed, subglobose to globose; opercula conic, shortly rostrate; annuli weakly differentiated; peristome double; exostome teeth linear-lanceolate to narrowly lanceolate, usually dorsally papillose, rarely smooth; endostome segments linear, as long as the teeth or fragile, rudimentary; basal membrane low; cilia absent. Calyptrae mitrate, smooth. Spores endosporic, ca. 75 µm in diameter, smooth.
