The lichens and allied fungi from the Leningrad Region and Saint Petersburg in the lichen herbarium of the University of Tartu

The revision of specimens in the lichen herbarium of the University of Tartu revealed 127 specimens representing 86 species from the Leningrad Region and Saint Petersburg; these include Calicium adspersum published as a new species for the Leningrad Region and Carbonicola anthracophila reported for the first time for the Eastern Leningrad Region. A curious finding is Umbilicaria muehlenbergii, collected in 1954 in the northern part of Karelian Isthmus. Forgotten collections by Anne-Liis Sõmermaa (1972) from the territory of the modern Vepssky Forest Nature Park, by Haide-Ene Rebassoo (1988) from Maly Tuters Island (Vähä-Tytärsaari, Säyvö) and by Paul von Kühlewein (“regio Petropolitano”, 19th century) are of special interest.
