In this study; we analysed the ITS sequences of 9 lichenized fungi species (Aspicilia cinerea, Circinaria contorta, Lecidea atrobrunnea, Lecanora rupicola, Physcia dubia, Rhizoplaca peltata, Rhizocarpon geographicum, Tephromela atra and Xanthoparmelia pulla) which have a wide distribution in the alpine zone of Erciyes Volcanic Mountain in Central Anatolia. ITS sequence data obtained from those 9 species are deposited by us in GenBank for further molecular studies and Neighbor-joining dendrograms with related species obtained from GenBank are also presented here along with the macroscopic photographs of the specimens studied. Besides, morphological and ecological differences between the related species are discussed.
