Specimens deposited in the YSU Fungarium were collected mainly in the taiga zone of Western Siberia (Russia). The majority of specimens were collected in Khanty-Mansiyskiy Autonomous Okrug (3439 specimen), 11 specimens from Yamalo-Nenetskiy Autonomous Okrug, while the rest four regions represented by a few specimens (Krasnoyarskiy Kray, Novosibirskaya Oblast’, Altay Republic, Tyumenskaya Oblast’). Within administrative borders of Khanty-Mansiyskiy Autonomous Okrug, 6 districts are represented (Khanty-Mansiyskiy district – 3421 specimens, Sovetskiy district – 7, Berezovskiy district – 6, Nefteyuganskiy district – 3, Surgutskiy district – 2, Beloyarskiy district – 1). The two main sampling areas are located in the vicinities of Khanty-Mansiysk (60N 68E) and the nearby Shapsha (1959 specimen) and Mukhrino field stations of the YSU (1459 specimens).
Major vegetation types covered by the collection are coniferous dark taiga forests and their deciduous derivates (more than half of the collection), and ombrotrophic raised bogs (comprising about 30% of the collection). Exact classification of vegetation types is not managed in the database, where “vegetation” field is temporarily descriptive; eventually it will be worked out. Coniferous forests (dominated by Pinus sibirica, Picea obovata, and Abies sibirica) and their deciduous successions (Populus tremula, Betula pubescens) are characteristic for the taiga zone of Western Siberia. The region is highly bogged, with ombrotrophic peatlands covering about 50% of the area. Other major landscapes include floodplains of big rivers, where meadow and floodplain shrub vegetation develops.
