Revision of specimens of the lichen genera Acarospora, Lecanora and Ramalina from former private herbarium of Ludwig Meinunger

Specimens of the genus Acarospora as well as of Lecanora hybocarpa, L. sinuosa and Ramalina baltica from the former private herbarium of Ludwig Meinunger were revised. The here published specimens of Acarospora intermedia are the first records for the German landscape units Mecklenburgisches Ruckland (Mecklenburg-Vorpommern), Main-Tauber-Gebiet (Bavaria) und Vogtland (Thuringia). The occurrences of Acarospora gallica, A. rugulosa and Lecanora sinuosa in Thuringia were confirmed. Lecanora hybocarpa is to be deleted from the Thuringian checklist. Acarospora nitrophila and Ramalina baltica are classified as doubtful in Thuringia.
