taxonomic_comments

Originally placed in the genus Hydrothyria, this lichen was found to be a species of Peltigera through molecular analysis. Further molecular analysis revealed three taxa, two in the Pacific Northwest and our eastern taxon found in the Appalachians. While the three taxa are varieties, the eastern variety is also the typical variety and thus is considered a synonym (autonym) of the species, and is so here named at the species level.
