Two new species, Hypogymnia tuckerae and H. discopruina (Parmeliaceae), from North America and China
Hypogymnia tuckerae is a newly described sorediate lichenized fungus currently known from three sites in the Cascade Range in Oregon, three sites in northern California, and one site in the Blue Mountains of northeastern Oregon. Although we have known a few of these anomalous sorediate specimens for...

Hypogymnia tuckerae is a newly described sorediate lichenized fungus currently known from three sites in the Cascade Range in Oregon, three sites in northern California, and one site in the Blue Mountains of northeastern Oregon. Although we have known a few of these anomalous sorediate specimens for many years, taxonomic action was stymied by possibilities that they were rare sorediate morphs of a normally fertile species, H. wilfiana, or a rare chemotype of a normally sorediate lichen, H. oceanica. ITS and GPD1 sequences demonstrated that neither is the case; instead, H. tuckerae occupies an isolated position in phylogenetic reconstructions. With ITS alone, however, H. tuckerae is sister to the largest clade of Hypogymnia species from the southern hemisphere. Esorediate individuals of H. tuckerae are very similar to H. antarctica (South America), H. metaphysodes (Japan), and H. wilfiana (North America).
