Abstract. Abandoned agricultural lands (fallow lands), which are actively overgrown with woody vegetation, occupy a significant area in the NorthWestern Federal District. In the first decades of the wood reserve growth, these forests are not of interest to the logging industry. At the same time, small woody detritus appears in them, and small-sized live trees provide an opportunity to obtain raw materials of chaga mushroom (Inonotus obliquus). Accordingly, such sites are a promising site for industrial mushroom farming. This paper presents the results of an experiment on the Inonotus obliquus, Lentinula edodes and Kuehneromyces mutabilis species cultivation in the natural conditions of postagrogenic ecosystems in the Pskov region. These experiments showed that the substrate overgrown with deciduous young growth can be used for the successful cultivation of these fungi. Live trees were infected by Inonotus obliquus, trunk clippings up to 12 cm in diameter by Lentinula edodes and Kuehneromyces mutabilis. Substrate occupation and the first fruit bodies of mushrooms/sterile outgrowths appeared in Inonotus obliquus 10 years later, in Lentinula edodes and Kuehneromyces mutabilis – the next year after infection. The periods of mass fruiting in Lentinula edodes were 3 years, in Kuehneromyces mutabilis – 2 years. These results show the potential for successful cultivation of these fungi species in postagrogenic ecosystems and may be useful for the development of industrial mushroom production in this region. Inoculation technologies for these mushrooms in open-air conditions may be considered promising in terms of minimizing capital costs for establishing plantations, as well as serving as a component of comprehensive forest use in agricultural lands.
