Fuscopannaria mediterranea and F. sorediata (Pannariaceae, lichenized Ascomycota), new records for the Far East of Russia

Two new records of Pannariaceae lichens – Fuscopannaria mediterranea and F. sorediata were registered for the Russian Far East using DNA and morphological investigation of the samples collected from the Sakhalin and Kuril Islands. Both species are morphologically problematic to distinguish from other sorediate species of the genus Fuscopannaria. Fuscopannaria mediterranea is reported for the first time to East Asia supported by the ITS nrDNA molecular-phylogenetic data. After investigation of the material from Sakhalin and Kuriles we excluded Fuscopannaria confusa and F. leprosa from the species list of the Russian Far East. The rest controversial material from Sakhalin and Kuriles was identified as F. alhneri as the most common species of the genus in the region.
