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.

Three lichen species and eight lichenicolous fungi were recorded for the first time for St. Petersburg or Eastern Leningrad Region. In addition, the protected species Lobaria scrobiculata was rediscovered in the Leningrad Region. The lichenicolous fungus Arthonia parietinaria is new to Russia, and two species, Didymocyrtis melanelixiae and Tremella everniae, are new for European Russia

New records of lichens and allied fungi from the Leningrad Region, Russia

Twelve species of lichenized and two lichenicolous fungi, and one non-lichenized calicioid fungus are reported from the Leningrad Region (Eastern, Western or Saint-Petersburg). Lecanora norvegica and Opegrapha lamyi are reported for the first time for Russia. Six taxa are also new to the whole Leningrad Region; four, Lecidella flavosorediata, Ochrolechia bahusiensis, Phaeocalicium praecedens and Tremella lichenicola – to North-Western European Russia, and one, the anamorphic lichen Dictyocatenulata alba is new to European Russia. Brief discussions on the species are included.

Eight species of lichen-forming, eight lichenicolous and three non-lichenized fungi are reported from the Leningrad Region. Arthonia caerulescens, A. ligniaria, Hawksworthiana peltigericola, Micarea pycnidiophora and Trichonectria rubefaciens are new to Russia; Micarea lutulata, Protoparmelia oleagina and Stictis radiata are new to the North-Western European Russia; Lichenoconium lecanorae, Phaeocalicium populneum, Phaeosporobolus usneae, Ramboldia cinnabarina, Stictis brunnescens and Strigula stigmatella are new to the Leningrad Region.

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

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

Konevets Island (Leningrad Region, Russia) – a historical refuge of lichen diversity in Lake Ladoga

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
