Abstract

The genus Cortinarius is one of the largest in the world among lamellar macromycetes, but in Ukraine the species of this genus are insufficiently studied. Тhe article presents the results of mycological studies of the genus Cortinarius during 2010–2020 in the National Natural Park «Hutsulshchyna». The main goal was to study the species composition of the genus Cortinarius in NNP and to identify rare taxa. Field research was carried out on the territory of NNP «Hutsulshchyna» by route-expedition method. As a result, 41 species of the genus Cortinarius were identified, among which one species of C. сaperatus is included in the IUCN lists. The genus under study is a mycorrhizal macromycetes. Among the identified species, 41 % are common in all forest ecosystems, 29 % are highly specialized (associated with specific parterre trees), 8 % grow only in deciduous forests and 10 % – in conifers. The narrowly specialized ones include: Cortinarius flexipes (birch), C. argentatus, C. prasinus (beech), C. purpureus, C. rubellus, C. variicolor (spruce), C. acutus, C. mucosus, C. mucifluoides, C. sanguineus, C. traganus, C. violaceus (pine). The analysis is made: the ratio of the number of species of the genus Cortinarius in the world and in Ukraine, the species richness of the studied genus using the Turing coefficient, the distribution of species by categories of abundance and by affiliation to tree species. The most common species on the territory of NNP «Hutsulshchyna» were: Cortinarius anomalus, C. caerulescens, C. caperatus, C. delibutus, C. multiformis, C. trivialis, C. violaceus. Rare in the NNP include 13 species: Cortinarius camphoratus, C. eburneus, C. hemitrichus, C. flexipes, C. mucifluoides, C. mucosus, C. pholideus, C. praestans, C. prasinus, C. rubellus, C. traganus, C. triumphans, C. variicolor. Іn the Ukrainian Carpathians 19 genus: Cortinarius acutus, C. argentatus, C. armillatus, C. bolaris, C. caerulescens, C. decipiens, C. mucosus, C. hemitrichus, C. flexipes, C. mucifluoides, C. eburneus, C. ochroleucus, C. pholideus, C. praestans, C. prasinus, C. purpureus, C. torvus, C. triumphans, C. trivialis are registered only on the territory of National Natural Park «Hutsulshchyna».
