The epilithic and epigeic lichen flora of eight localities with granite and gneiss outcrops in the mountains of Makedonia, N Greece has been investigated. Of the 46 taxa reported, seven species are new to Greece, viz.: Brodoa oroarcti­ca, Candelariella coralliza, Cetraria ericetorum, Lecanora swartzii, Parmelia serrana, Pseudephebe pubescens and Ramalina strepsilis. One species is new to the Greek mainland (Umbilicaria polyphylla) and four species are new to the region of Makedonia (Bryoria chalybeiformis, Melanelia disjuncta, Polychidium muscicola and Xanthoparmelia loxodes). Altitudinal range and abundance are briefly discussed for a number of species.
