Phylogenetic study and taxonomic revision of the Xanthoparmeliamexicana group, including the description of a new species (Parmeliaceae, Ascomycota).

ABSTRACT: Xanthoparmelia (Parmeliaceae, Ascomycota) is the most species-rich genus of lichen-forming fungi. Species boundaries are based on morphological and chemical features, varying reproductive strategies and, more recently, molecular sequence data. The isidiate Xanthoparmeliamexicana group is common in arid regions of North and Central America and includes a range of morphological variation and variable secondary metabolites - salazinic or stictic acids mainly. In order to better understand the evolutionary history of this group and potential taxonomic implications, a molecular phylogeny representing 58 ingroup samples was reconstructed using four loci, including ITS, mtSSU, nuLSU rDNA and MCM7. Results indicate the existence of multiple, distinct lineages phenotypically agreeing
