Remarkable collections of lichens from Austria, especially from Styria, are recorded. 25 species and 1 subspecies (probably better species) are new to Austria; in addition to these, 12 species are new to Styria. The taxa are annotated, and the taxonomy, ecology and geographical distribution of some groups are discussed in more detail: Cladonia uncialis with special regard to subsp. biuncialis, and some groups oí Aspicilia, especially A. calcarea coll. , and the species of arctic-alpine distribution currently comprised within the formally defined sect. „Orbiculares". A preliminary key to the latter group is provided.
