Fungi of the Russulaceae family in the conditions of natural monuments of the Penza region and the influence of environmental factors on their distribution

The relevance of the study fungi Russulaceae family is determined by fact that they play an important role in life temperate forest ecosystems as mycorrhizal symbionts main forest-forming tree species. In addition, this group great practical importance, are edible fungi. Despite this, one little studied groups Agaricomycetes. information about conditions Russian Federation limited, and therefore data on their ecology contained mainly foreign literature. purpose work to species composition establish influence environmental factors distribution territory some natural monuments regional significance (Burchikhinsky slopes, Zasursky blueberry forest, Kichkleysky pine with oak, Nikonovsky Floodplain oak forest) Penza region. studies were carried out 20162022 methods route stationary studies. When determining fungi, method light microscopy was used. As a result, located region studied. Within protected areas, 78 identified. result taxonomic analysis mycobiota, it found included 24 from genus Lactarius, 3 Lactifluus, 51 Russula. All them belong ecological-trophic symbiotrophs. 19 form mycorrhiza various species, 59 have narrow specialization relation partners symbiosis (29 associated Quercus robur, 15 Betula pendula, 10 Pinus sylvestris, 2 Populus tremula, 1 Tilia cordata, Alnus glutinosa Corylus avellana). It has been established leading spatial productivity fruiting bodies soil fertility moisture. megatrophic habitat conditions, acidity also significant effect under consideration. for types accordance edaphic grid. For different ecotopes, indicator revealed. An estimate yield forests, depending moisture, given.
