Physconia labrata, a new species from western North America and Asia
A new species belonging to the lichen genus Physconia is described from Alaska and the Canadian and American Rocky Mountains and adjacent forested regions. It is also reported from China, Nepal, India and Siberia. The new species, Physconia labrata, is superficially similar to P. perisidiosa, but can be distinguished by having a blackened, corticate lower surface and a paraplectenchymatous upper cortex
The brown parmelioid lichen species in Greenland
Sixteen species of brown parmelioids are reported from Greenland, including one species of Cetrariella, three species of Melanelia, two species of Melanelixia, six species of Melanohalea, and four species of Montanelia. Descriptions and a key are provided
Parmelia barrenoae, a macrolichen new to North America and Africa
The foliose lichen Parmelia barrenoae is newly reported for North America based on material collected throughout the western United States (California, Idaho, Oregon, and Washington) and for Africa based on material from the Middle Atlas mountain range of Morocco. In addition to morphology, ITS sequence data were examined to confirm the identity of North American material. The species was originally described from the Iberian Peninsula of Europe, and has not been reported from anywhere outside of that region since its description. A revised account of the species is provided in light of the additional material now available from geographically diverse populations
