Abstract

The quantitative registration of macromycete fruiting bodies was performed during two field seasons in the pine plantations of recultivated waste dump (experimental area) and in the pine forests on zonal soils (control area). The average quantity of carpophore macromycetes on the experimental area during two years of research exceeded ones on the control area by 41%. The field season of 2020 was characterized by significantly increased productivity of fungi in the studied areas; two peaks of mass fruiting of macromycetes were registrate. The maximum frequency of fruiting bodies of higher fungi was discovered in the autumn peak of mass fruiting mediated mainly by fair appearance of symbiotrophic fungi. Both studied areas in the different years of research were characterized by oppositely processes providing the distribution of carpophore macromycetes in pine plantations with different crown density (sparse, medium and dense). Taking into account the crown projection zones, the maximum frequency of macromycete fruiting bodies was located in the near-crown and outer zones of Pinus sylvestris L. trees.
