Four days of lichenological excursions in the surroundings of Sajathütte and Eisseehütte (Prägraten, High Tauern) resulted in the list of 428 lichen taxa, 13 lichenicolous fungi and 2 lichen-associated fungi. Five species (Catillaria cf. nigroisidiata, Micarea fennica, Microcalicium loraasii, Placynthium pulvinatum and Rinodina cf. calcigena) are first records for the Alps. In addition to the taxa mentioned, a further ten lichens are new to Austria: Caloplaca approximata, C. fuscorufa, Candelariella aggregata, Halecania spodomela, Lempholemma cladodes, L. isidioides, Porina rosei, Protoparmelia leproloma, Protoparmeliopsis bolcana, and Stereocaulon capitellatum. The area harbours an extraordinarily rich lichen diversity. The combination of high-mountain elements with continental or even xerothermic species is remarkable. Key words: arctic-alpine lichens, biodiversity, continental lichens, Eastern Alps, Tyrol.
