Abstract: The fatty acid (FA) compositions of 14 wild wood-decaying basidiomycete species (Bjerkandera adusta, Daedaleopsis septentrionalis, Dichomitus squalens, Inonotus hispidus, I.radiatus, Irpex lacteus, Fomitopsis cajanderi, F.pinicola, F. rosea, Gloeophyllum protractum, Lenzites betulina, Phellinus pini, Trametes gibbosa, T. ochracea) growing in permafrost conditions in Katanga region (Russian Federation) were investigated using GC-MS. Generally, C18:2 ω 6 (linoleic acid), C18:1 ω 9 (oleic acid), C16:0 (palmitic acid) and C20:0 (arachinic acid) were found to be the major FA in fungal species. Data about chemical components of Daedaleopsis septentrionalis , Fomitopsis cajanderi and Gloeophyllum protractum were obtained at the first time. Increased level of degree of FA unsaturation was probably a result of extreme environmental conditions.

Keywords: Wood-decaying basidiomycetes; fatty acids; GC-MS; permafrost conditions.
