Abstract

The study discusses the fruiting of fungi of the genus Suillus in artificial plantations of Pinus sylvestris L. on the rock dump at the Kedrovsky coal mine (experimental site) and in the pine forests of the Kuzbass Botanical Garden (control site), located on the territory of Kemerovo. The pine plantations at the experimental sites were distributed according to the degree of forest canopy closure. Three sites with different crown closure were identified: sparse closure (20–30%), moderate closure (50–60%), and high closure (80–90%). Within each site, three zones of crown projection were assigned (sub-crown, near-crown, and external). Field studies were carried out during the summer and autumn of 2019. Two species of macromycetes of the genus Suillus are found on the studied sites: Suillus granulatus (L.) Roussel and Suillus luteus (L.) Roussel. Mushrooms growing in pine plantations on reclaimed overburden dumps start fruiting earlier with longer fruiting than that in pine forests on zonal soils. The highest yields of mushrooms are found in pine stands with sparse closure. In the projection of the tree crown, the number of Suillus fungi increases in the direction from the trunk of the tree to the periphery of the crown and beyond (in sparse closures).
