Recent lichenological investigations add new and noteworthy records of lichen-forming and lichenicolous fungi to the Aggtelek National Park, especially from the Szalonna-Karst region (Mt Esztramos near Bódvarákó, Mt Szár-hegy near Martonyi). Altogether 64 records of 38 species of lichen-forming fungi and 13 species of lichenicolous fungi are presented and annotated. Agon imia globulifera, Lecanora compallens and The alloidima physaroides have been reported from the Aggtelek National Park for the first time, and all the lichenicolous fungi (Athe lia arachnoidea, Bryostigma parietinarium, Bryostigma phaeophysciae, Didymocyrtis slaptonensis, Illosporiopsis christiansenii, Lichenochora obscuroides, Lichenoconium erodens, Lichenodiplis lecanorae, Pronectria robergei, Pyrenochaeta xanthoriae, Roselliniella cladoniae, Xanthoriicola physciae, Zyzygomyces physciacearum) are also new to the Aggtelek National Park.
