The Hungarian lichenologist Odon Szatala described 169 species and infraspecific taxa, with a majority of these being based on his own collections. He also described taxa from material sent to him for identification. In this study, original material for 27 names (Aspicilia latiloba, A. microspora var. astroidea, A. microspora var. insensibilis, A. subpercaena, Bacidia rhodi, Buellia samothrakiana, Catillaria lenticularis var. transsilvatica, C. servitii, C. zsakii, Dermatocarpon fuscatum, Diplotomma alboatrum var. virescens, Lecania nylanderiana var. ochracea, Lecanora atra var. aegaeica, L. cengiae-samboae, L. rhodi, Lecidea aegaeica, L. aegaeica f. acrustacea, L. aegaeica f. albida, L. aegaeica var. verruculosa, L. euphorea f. decussata, L. iranica, L. stigmatea f. armeniaca, Pertusaria baskalensis, Physcia grisea var. elbursiana, Placodiella olivacea var. stampaliana, Porina rechingeri and Verrucaria filarszkyana) of taxa described by Szatala and based on material collected by others from Greece, Hungary, Iran, Iraq, Jordan, Palestine, Romania, Turkey and Ukraine was examined, and lectotypes were chosen. In addition, Catillaria servitii has been found to be the earliest name for C. praedicta.
