    The lichens of the Cladonia pyxidata-chlorophaea complex in Belarus

    Get PDF
    Based on an examination of c. 500 herbarium specimens of the Cladonia pyxidata-chlorophaea complex, this study deals with their morphology, secondary chemistry, habitat requirements and distribution in Belarus. Eleven taxa have been accepted, of which C. conista, C. cryptochlorophaea, C. homosekikaica, C. merochlorophaea, C. monomorpha and C. novochlo- rophaea are new to the country. Cladonia grayi appears to be the commonest species in the country (c. 40% of the studied specimens), and C. pyxidata is uncommon in Belarus, known only from 10 localities. The chemotypes of the species and their frequency in Belarus are indicated

    Didymocyrtis epiphyscia (Phaeosphaeriaceae) is new to Kazakhstan and Central Asia

    Get PDF
    Didymocyrtis epiphyscia s. lat. is reported for the first time for Kazakhstan and Central Asia. Anatomical characteristics of studied material are provided. Taxonomic difficulties of the D. epiphyscia complex are discussed. A possibly new lichenicolous Didymocyrtis species (on Parmelia sulcata) with non-guttulate conidia is described, illustrated and discussed

    Lichenicolous fungi from the Samara Region, southern part of European Russia

    Get PDF
    Twenty two species of lichenicolous and two occasionally lichen-inhabiting fungi are reported from the Samara Region. Twenty three of them are new to the region, eighteen – to southern part of European Russia; Intralichen lichenum is new to European Russia, and Phoma grumantiana and Pyrenidium crozalsii are reported for the first time for Russia.

    The genus Lepraria (Stereocaulaceae, lichenized Ascomycota) in Belarus

    Get PDF
    Based on an examination of 360 herbarium specimens of the genus Lepraria, this study deals with their morphology, secondary chemistry, habitat requirements and distribution in Belarus. Nine taxa have been accepted, of which L. ecorticata, L. finkii and L. rigidula are new to the country. L. incana appears to be the commonest species in the country (48% of the studied specimens)

    The red-listed Cetrelia cetrarioides (Parmeliaceae) is confirmed by molecular data in Belarus

    Get PDF
    The new locality of the Red-listed lichen Cetrelia cetrarioides was discovered in Belovezhskaya Puscha National Park. The occurrence of this species was confirmed by the sequence of the ITS region

    The lichen genus Xanthoparmelia (Parmeliaceae) in Belarus

    Get PDF
    Two hundred six specimens of Xanthoparmelia collected in Belarus in 1905–2017 were examined based on morphological and chemical characters. Six species (X. angustiphylla, X. conspersa, X. delisei, X. loxodes, X. pulla and X. verruculifera) were identified in this study. Xanthoparmelia angustiphylla and X. delisei are reported for Belarus for the first time. Presence of Xanthoparmelia pokornyi and X. stenophylla has not been confirmed, and therefore these species should be excluded from the Belarusian list of lichens. A key to the species of Xanthoparmelia in Belarus is provided

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

    Get PDF
    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 lichenicolous fungi from the Gomel Region of Belarus

    Get PDF
    Three species of lichenicolous fungi, Roselliniella cladoniae, Taeniolella beschiana and Trichonectria rubefaciens, are reported for the first time for Belarus; two further species, lllosporiopsis christiansenii and Marchandiomyces aurantiacus, are new to Gomel Region, the south-eastern part of Belarus.

    Where the interesting species grow – remarkable records of lichens and lichenicolous fungi found during a Nordic Lichen Society meeting in Estonia

    Get PDF
    In August 2019, the Nordic Lichen Society held its bi-annual meeting and excursion in south-western Estonia. The most remarkable findings of lichenized and lichenicolous fungi are recorded herewith, including nine new species (of them two lichenicolous), and one new intraspecific taxon for the country. Full species lists are provided for two notable locations, sandstone outcrop at the river Pärnu and an oak woodland in the Naissoo Nature Reserve, for which no previous data were available, to illustrate the importance of collective survey effort.   2019. a augustis toimus Eestis korraline, iga kahe aasta järel korraldatav Põhjamaade Lihhenoloogide Ühingu kokkutulek ja ekskursioon. Artiklis anname ülevaate huvitavatest lihheniseerunud ja lihhenikoolsete liikide leidudest, sealhulgas üheksa (neist kahe lihhenikoolse) liigi esmaleiust Eestis ja ühe liigisisese taksoni esmaleiust. Lisaks esitatakse lihheniseerunud, lihhenikoolsete ja neile lähedaste seente täisnimekirjad, mis koostati kahe elupaiga – Tori Põrgu Maastikukaitseala liivakivipaljandi ning Naissoo Looduskaitseala koosseisu jääva Naissoo tammiku – kohta
