    Lichenicolous fungi of southern Scandinavia with particular reference to those associated with Xanthoria calcicola s. lat.

    Get PDF
    Lichenicolous fungi associated with Xanthoria calcicola s. lat. are studied in southernmost Scandinavia, i.e., Skåne, the southernmost province in Sweden and southern Denmark. Two species, Didymocyrtis slaptoensis and Pyrenochaeta xantho­ riae, are reported as new for the Nordic countries, whereas three species, Didymocyrtis cf. consimilis, Erythricium aurantiacum, and Illosporiopsis christiansenii are recorded for the first time from Skåne. New localities for rare lichenicolous fungi from southern Scandinavia and southernmost Denmark are also listed. Notes on the taxonomy and ecology of Telogalla olivieri and Pyrenochaeta xanthoriae are provided

    Get PDF
    The compilation of the current Red List of Estonia took place during 2006–2008; the IUCN system of categories and criteria (vers. 6.1), which is accepted worldwide, was applied. Out of the 1019 lichenized, lichenicolous and closely allied fungal species recorded in Estonia in 2006, 464 species (45.5%) were evaluated while 555 species remained not estimated – in the category Not Evaluated (NE). Of the evaluated species, 213 were assigned to the so-called red-listed categories: Regionally Extinct (RE), Critically Endangered (CR), Endangered (EN), Vulnerable (VU), Near Threatened (NT) and Data Deficient (DD). 113 of them were classified as threatened (belonging to the categories CR, EN, VU). 251 species were assigned to the category Least Concerned (LC). The full enumeration of the red-listed lichens of Estonia with appropriate category and criteria is presented.

    Ten lichenized fungi are reported as new to Estonia: Atla wheldonii, Bacidia coprodes, Bacidina assulata, Bacidina brandii, Candelariella lutella, Gyalidea fritzei, Piccolia ochrophora, Protoparmelia oleagina, Sclerophora amabilis and Strangospora deplanata. One lichenized fungus, Leptogium subtile, has been reported from Estonia earlier, but all the specimens of this species in the herbarium of University of Tartu appeared to be misidentifications; currently the species has one certain locality in Estonia.
