摘要

Parmelina quercina is a well-studied foliose macro-lichen found on rocks and trees in the Northern Hemisphere. Recent studies support multiple species within P. quercina based on material from Europe, North America and western Asia. The identities of Parmelina quercina s.lat. reported from eastern Asia and Alaska remain unknown. We compared DNA sequences, secondary chemistry and morphological traits of Parmelina from Alaska, Russia and China. These data support the resurrection of Parmelina yalungana to accommodate eastern Asian and Alaskan material. Parmelina yalungana differs from congeners in ascospore dimensions, geographic range and molecular data from three gene loci. We place P. yalungana in the phylogenetic context of the P. quercina group using DNA from Alaskan and Russian material.
