DNA barcode identification of lichen-forming fungal species in the Rhizoplaca melanophthalma species-complex (Lecanorales, Lecanoraceae), including five new species

摘要: Recent studies using sequence data from multiple loci and coalescent-based species delimitation have revealed several species-level lineages within the phenotypically circumscribed taxon Rhizoplaca melanophthalma sensu lato. Here, we formally describe five new this group, R. occulta, parilis, polymorpha, porterii, shushanii, support method implemented in program Bayesian Phylogenetics Phylogeography (BPP) as diagnostic feature distinguishing species. We provide a reference DNA database ITS marker barcode for identifying complex. also assessed intraspecific genetic distances six lato While were less than or equal to lowest interspecific pairwise comparison values, an overlap stricto clade suggests potential additional Copyright Steven D.
