Hypogymnia phylogeny, including Cavernularia, reveals biogeographic structure
We inferred phylogenetic relationships using Bayesian and maximum likelihood approaches for two genera of lichenized fungi, Hypogymnia and Cavernularia (Parmeliaceae). Based on the combined ITS and GPD1 dataset from 23 species (49 specimens) of Hypogymnia and two species (8 specimens) of Cavernulari...
