The fungal biota was studied in 2019 in a test plot in pine stands planted on the spoil dump of the Kedrovsky coal mine, and in a control plot in pine stands on zonal meadow chernozem soils in the Kuzbass Botanical Garden. In these plots, the number of fruit bodies was counted every seven days of the summer-autumn period, the fungi were photographed and identified. Surveys revealed 43 species of macrofungi in the Kedrovsky coal mine remediation sites, and 33 species of higher fungi on the zonal soils of the Kuzbass Botanical Garden. Abundant fruiting of macrofungi was observed in the stands planted of the spoil rock dump of the Kedrovsky coal mine. The number of fruit bodies formed in the mushroom community of pine forests in the control plot was 15 % lower on average. The trophic structure of the fungal biota in the plant community on the spoil dump was characterized by a high diversity of mycorrhizal species (18 species), while the group of litter saprotrophs was less diverse (13 species). The amount of soil-, litter-, and humus- dwelling saprotrophs was minor. The prevalent group in pine forests of the Kuzbass Botanical Garden, on zonal soils, was litter-dwelling saprotrophs (17 species), whereas mycorrhizal fungi were less numerous there (10 species), and the rest of trophic groups were represented by single specimens. The fungal biota of the remediated Kedrovsky coal mine areas featured high species richness and abundant fruiting, and the fungal species inhabiting the areas are typical of the Kemerovo Region. The prevalent component of the trophic structure of the fungal biota in the pine stands on remediated land was symbiotrophic fungi, forming ectomycorrhiza with woody plants, thus supplying the latter with nutrition in the oligotrophic conditions of technogenic residual rock. The presence of fungi of different trophic groups indicates that the dump habitats are involved in many ways in the biological cycle under the pine stand cover.
