612 lichens and 51 lichenicolous fungi are reported from the „Seetaler Alpen" (Styria, Austria). Some of them are apparently new to Styria or even new to Central Europe. About 30 species of different lichen genera have been analysed by thin layer chromatography. Siliceous rocks are dominant in the studied area (650-2396 m), but some marble outcrops occure. Especially in the valley of Neumarkt a more continental climate favours the occurence of moderately xerothermic lichen associations. „Oceanic" lichen elements are either missing or restricted to localities with a favourable microclimate. A new combination is proposed: Carbonea distans (KREMPELH.) HAF. & W. OBERMAYE
