Abstract

Hypotrachyna virginica was long considered to be an endemic Appalachian macrolichen until it was recently reported from the Caribbean. Here we show that Neotropical material identified as H. virginica is morphologically distinct from that species and instead is conspecific with H. exsecta, a species widespread in the Paleotropics. Both species have also previously been confused with H. laevigata, which is widespread in the Americas and Europe. A revision of the three species is presented, including descriptions, illustrations, distribution maps, and global IUCN red-list assessments.
