A molecular survey was conducted of lichenised Prasiola specimens from Alaska, Tierra del Fuego and Antarctica. Genetic data were generated for two nuclear loci (nrITS, RPL10A) and a chloroplast locus (tufA). A discovery-validation approach was used for Prasiola species delimitation. We identified two Prasiola species forming lichens with Mastodia tessellata. Lichenized Prasiola species showed contrasting distribution ranges.
