general taxon notes:

Calliergonella is similar to Calliergon in general appearance and shares similar habitats, but it differs from the latter by 1) the double or absence of costae; 2) the hyaline cortical cells of stems; 3) the plicate perichaetial leaves; and 4) the differentiated annuli. It is a monotypic genus with C. cuspidata (Loeske 1911). Grout (1931) combined Pleurozium Mitt. into Calliergonella. Karczmarz (1971) treated Calliergonella as one of the sections in Calliergon. Kanda (1976) considered Calliergonella closely related to the Hypnaceae. Nishimura et al. (1984) treated Calliergonella under the Hypnaceae. Hedenäs (1990)[1992] reduced Breidleria arcuata (Molendo) Loeske of the Hypnaceae to a synonym of Calliergonella lindbergii (Mitt.) Hedenäs.

 
Two species of Calliergonella are recognized in the world (Crosby et al. 2000), and both are found in China.
