Phylogeny of Cladonia uncialis( Cladoniaceae, Lecanoromycetes) and its allies
Abstract The species from Cladonia section Unciales are characterized by the absence of squamules and soredia on the corticate podetia and the presence of usnic acid. Different subspecies, varieties and forms have been distinguished in the type species C. uncialis . In this study, a molecular phylog...
