Introduction. We found an unusual specimen collected in 1975 from Xinjiang Province, China which may represent Grimmia exquisita J.Muñoz. However, this species is known only from the type localities and its taxonomic status is still controversial. Methods. A voucher of the Chinese specimen is deposited in IFP herbarium. This specimen was studied with the typical anatomical and morphological methods applied within Grimmia (Maier, 2010). Key Results. The Chinese species represents G. exquisita. After examining the type specimens of G. exquisita, we confirmed that it should be recognised as a distinct species. Conclusions. This study expands the distribution area of G. exquisita to East Asia. The Chinese specimen was discovered in a rather different habitat to its types and consequently, G. exquisita may be a more widely distributed species. Evaluation of the Grimmia specimens in many different herbaria is needed.
