Abstract:

A revision of Canoparmelia from the Hengduan Mountains (Yunnan, China) revealed the occurrence of Cecaperata, based on specimens previously identified as Parmotrema conformatum. Cecaperata is hereby reported as new to the flora of China. The study also led to the identification of Ctexana as a component of the flora of Yunnan. In order to make sure the systematic position of these species, a phylogenetic analysis of rDNA ITS sequence was also carried out in this paper, indicating that Cecaperata is closely related to Ctexana and Cconcrescens. Detailed information and discussion of these two new records are provided, together with a key to all the known taxa of Canoparmelia recorded from China. Following our revision, Parmotrema conformatum should be excluded from the flora of China.

Key words: Canoparmelia, New record, Geographic distribution, Molecular phylogeny
