    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.

    New and rare lichens and allied fungi from the Pskov Region, Russia

    Get PDF
    Forty-one species of lichens and two lichenicolous fungi are reported from the Pskov Region. Of them, thirty-nine species are new for the region, including Lempholemma dispansum – a rare species with scattered distribution, previously recorded only once in the European Russia in the 19th century. The most important findings are confined to ancient limestone outcrops and old manor parks: these habitats are also promising for further investigations, taking in account high level of anthropogenic transformation of the Pskov Region

    We present an updated checklist for Konevets Island (Leningrad Region, Russia). The revealed lichen biota comprises 435 species, including 378 lichens, 46 lichenicolous fungi and 11 non-lichenized saprobic fungi, of which 31 species (27 lichens and 4 lichenicolous fungi) are known only from collections made by Veli Räsänen (1917, 1938). Acremonium hypholomatis is reported for the first time for Russia; Caloplaca soralifera, Trapelia corticola, and Muellerella lichenicola for Northwestern European Russia; and Bacidia vermifera, Lecanora mughicola, Micarea contexta, Pyrenochaeta xanthoriae, Rhizocarpon disporum, Stigmidium squamariae and Xylographa difformis for Leningrad Region. From lichenological point of view, the most valuable habitats of Konevets Island are old-growth spruce forests. The studied lichen biota is rich and diverse and exceptionally well-preserved in comparison to the mainland part of Karelian Isthmus. It definitely deserves protection
