Molecular phylogenetic analyses reveal two new synonyms of Xanthoria parietina
Molecular analyses of the recently described Xanthoria polessica collected fromthe type locality and of the Australian species X. coomae were used to determine whether these taxa are distinct species or fall within the wide phenotypic variation of the wellknown and cosmopolitan X. parietina. Our results clearly indicate that both taxa should be considered as synonyms of X. parietina since the infr
