Abstract: 7 fig. 5 tab. ["Gene genealogies of 6 and 12 loci were used to estimate the evolutionary history of Letharia, based on the principles of lineage sorting of alleles in divergent lineages after genetic isolation. Instead of a species pair consisting of a putative clonal species derived from a progenitor sexual species, Letharia comprises at least six phylogenetic species."]
