Acarospora sinopica, Alectoria gowardii, Austroplaca sibirica, Calogaya bryochrysion, Hymenelia ceracea, Porpidia ochrolemma , and Sagiolechia protuberans are new to the island and to the Russian Far East. Two lichen species ( Lecidea lithophila and Rinodina terrestris ), as well as two liverwort taxa ( Clevea hyaline , Lophoziopsis excisa var. elegans and Pseudolophozia debiliformis ), are new to the Chukotka Autonomous Area. Two of the reported moss species ( Funaria arctica and Schistidium umbrosum ) are extremely rare. Location data and ecological descriptions for the newly reported species are included
