Abstract
On the example of spruce forests of the European taiga of Russia, the most important functional positions of wood-destroying fungi (DRFs) in the genesis of forest communities are described. In spruce forests, the age structures of forest stands, the extent of damage to forests by the DRG of the biotrophic complex, the volume of tree waste, and the participation of fungi of the xylotrophic complex in the decomposition of deadwood biomass by stages of decomposition were studied. The graphic version shows the structure of the process of formation of the biomass balance of the indigenous taiga spruce forest, based on differences in the time periods of accumulation and decomposition of the biomass of woody fractions of indigenous sustainable spruce forests. DRGs perform the task of coordinating the processes of accumulation and decomposition of forest biomass, maintaining its balance in the dynamics of the forest community to a state of optimal sustainability. The participation of wood-destroying fungi in the formation of structures of sustainable spruce forest formations should be considered as the main paradigm of their functional tasks in forest communities.
