An annotated catalogue of the lichen-forming, lichenicolous and allied fungi of the Eastern Leningrad Region, Russia, is presented. It is based on our field trips, revision of herbarium specimens in herbaria in Russia, Finland and Sweden and a critical review of data in literature as well as archives. Altogether 520 species and two infraspecific taxa are recognized, among them 487 species of lichens, 20 species of lichenicolous fungi and 13 species of other allied fungi. During the project 107 species were recorded as new to the whole Leningrad Region, and 65 are reported here for the first time. Seven species were recorded as new to the Russian Federation. The red-listed lichens of the Leningrad Region are represented by 28 species. The best studied areas are the Nizhnesvirsky Reserve, Vepssky Forest Nature Park, and the Svir River valley in the Lodeynoe Pole, Podporozh'e and Tikhvin Districts, while the data from the more southern areas in Kirishi and Boksitogorsk Districts are still rather deficient. Many species have not been refound after the first reports and collections by F. Elfving in 1875.
