XYLOTROPHIC BASIDIOMYCETES OF OB-IRTYSH LEFT BANK AREA

Abstract

First mycological investigations conducted in dark coniferous and valley forests near the scientific station «Mukhrino» (Khanty-Mansiisk Autonomous District - Yugra) allowed to reveal 105 species, 1 subspecies and 1 variety of aphyllophoroid fungi from 65 genera, 26 families, 11 orders and 6 species of heterobasidial fungi from 4 genera, 2 families and 2 orders. Rare species known by solitary findings within the range were marked in the studied area: Antrodia mellita, Antrodiella foliaceodentata , Phlebia subochracea , Phlebia tremelloidea , or in boreal zone within Russia: Bjerkandera fumosa , Haploporus odorus , Hericium erinaceus , Pseudohydnum gelatinosum . 3 species: Antrodia mellita , Phlebia subochracea , Phlebia tremelloidea - were revealed for the first time in Western Siberia region, and 1 of them - Phlebia tremelloidea - is marked for the first time in Asian part of Russia. New habitats of 6 rare species included in the regional Red Book were defined within Khanty-Mansiisk Autonomous District: Antrodiella foliaceodentata , Ganoderma lucidum , Haploporus odorus , Hericium cirrhatum , Hericium erinaceus , Rigidoporus crocatus . The occurrence of large number of rare species within the area and regional rare species of aphyllophoroid fungi in mycobiota of the studied territory proves the uniqueness and high protection value of virgin forests of Ob-Irtysh left bank areas.
