X. mougeotii (Schaer.) Hale (1974: 488)

Xanthoparmelia mougeotii was reported from three localities in the study area by Nash et al. (1995). We have studied 17 specimens, and the species is probably common in our study area. All share the same chemistry of usnic, norstictic, stictic, constictic and cryptostictic acids, but three specimens also have menegazziaic acid, and some specimens also contain an unidentified substance. The soralia are more fine-grained and whitish as compared with those of X. submougeotii (Figs. 8 and 9).
