The paper studies mycobiota of the upper layer of pine forests litter in the parks of Surgut: Za Saimoy, Energetikov, Kedrovy Log, Neftyanik. The author identified 52 isolates of soil microscopic fungi belonging to 14 genera. Most of the isolates  anamorphic (mitospore) fungi  are represented by 9 genera: Acremonium, Annellosporium, Aspergillus, Fusarium, Humicola, Penicillium, Trichoderma, Ulocladium, Verticillium. Zygomycetes belong to three genera  Absidia, Mucor and Umbelopsis. Ascomycetes are represented by two genera: Eupenicillium and Talaromyces. The author also isolated Mycelia sterilia group. Representatives of the genera Absidia, Trichoderma, Fusarium and Penicillium are found in the mycocenoses of the studied parks. The genera Trichoderma, Fusarium and Penicillium also dominate by the number of isolates. Umbelopsis isabellina species is abundant in the Kedrovy Log park. Species of the genus Trichoderma are abundant in the Neftyanik park. Light-colored micromycetes of the group Mycelia sterilia are found and abundant only in the Za Saimoy park. Cellulolytics of the genus Trichoderma and the species Annellosporium nemorosum are abundant in the Energetikov park. Thus, mycobiota of the upper layer litter of the studied parks is close to the mycobiota of the background podzolic soils. It contains fungal species typical of the background soils. Fungi resistant to anthropogenic influences  dark-colored micromycetes Ulocladium alternarie and phytopathogenic species Verticillium dahlia var. longisporum. were found in the minority only in the Energetikov park. The obtained data allow us to conclude that the anthropogenic influence on the structure of the mycocenosis of the Energetikov park is more pronounced, but in general it does not have a significant effect on the mycobiota of the upper layer litter of the studied parks.
