Fleshy fungi forays in the vicinities of the YSU Mukhrino field station
The article sums up the results of studying the fleshy fungi biota in the vicinities of the Yugra State University Mukhrino Field Station (Khanty-Mansiysk, boreal zone of Western Siberia). Collections were made between 2008-2014 during forays in forest, floodplain and bog ecosystems. A total of approximately 600 specimens were studied using the standard methods and identified based on up-to-date monographs and floras. Dried specimens and metadata are stored in the YSU Fungarium. The species richness of the identified fleshy fungi mycobiota is made up of 324 taxa from 108 genera, 42 families and 10 orders. The majority of species (40%) are mycorrhizal with trees, the rest are saprobic on wood (25%), soil (20%) and other substrates. Fleshy fungi being an important food source, edibility of the finds was analyzed: 23% (71 taxa) are edible, including 30 species which are considered edible and good; 5% are poisonous, including several deadly poisonous species; 14% are edible with caution; information on the rest (57%) is not available in literature. Seven of the discovered species are currently redlisted in the Khanty-Mansi Autonomous Okrug (Yugra); information on the locations and state of populations is provided. The comparison of the list of the discovered taxa with the combined list of taxa from previously published works on Yugra fleshy fungi shows a high degree of novelty: only a third of the species were registered previously, and the rest (198 taxa) are new finds for the territory. The annotated checklist provides information on dates, locations, abundance, trophic groups and edibility of all discovered taxa.
