The materials to study of microfungi in Lebyazhy nature reserve (Lomonosov district of Leningrad region)

Abstract

Data about species of microfungi, collected in Lebyazhy nature reserve (Lomonosov district of Leningrad region) is presented. The living or dead parts of trees, shrubs, semishrubs and herbaceous plants mainly from Rosaceae, Salicaceae and Betulaceae are the main substrates for identified microfungi. Total of 67 species from Ascomycota, Basidiomycota and Oomycota were found and 36 of them were reported for the first time in the reserve. Many species are obligate parasites of plants, mainly from the orders Erysiphales (18 species) and Pucciniales (14 species). So, the most important plant diseases are powdery mildew and rust. The population of entering in the Red Book of Leningrad Region was examined for a special purpose. Two fungi species were found on it. They are Phacellium rufi basis (Capnodiales) that causes redish-brown spots on twigs and leaves and Cryptodiaporthe aubertii (Diaporthales) growing on dead brunches. Seven species of micromycetes are associated with plants of sandy shores — the specially protected sites of Lebyazhy nature reserve. Three of them are from Erysiphales and others — from Pucciniales, Ustilaginales, Rhytismatales and Capnodiales. Refs 24. Figs 2. Table 1.
