A new epiphytic species of crustose Teloschistaceae, Coppinsiella extremiorientalis, is described from the floodplain forests of the boreal zone of the Russian Far East. It is characterized by white to whitish grey, thin to disappearing thallus mostly without anthraquinones, dull orange zeorine apothecia with white pruina and anthraquinones composition corresponding to chemosyndrome A. Phylogeny of the genus Coppinsiella, which was previously unknown in the Far East, is discussed as well as morphology, ecology and geographical desctribution of its species. A new combination for Caloplaca fiumana, an older name for Coppinsiella orbicularis, is also proposed.
