general taxon notes:
This genus was known in the earlier literature as Eriopus Brid., an illegitimate name. It is characterized by ascending stems with complanate foliation, often bearing attenuate branches with highly branched, filiform propagula in the leaf axils. The very short double costae separate it from the genera with strong double costae, such as Actinodontium, Callicostella, Cyclodictyon, and Hookeriopsis.
Calyptrochaeta has about 30 species worldwide, and 2 species are recognized in China.
