Given piece of the research work was conducted in the seasons 2011-2018. The object of research was the mycobiota of macromycetes of the Botanical Garden of Belgorod State University (Belgorod, Russian Federation). The main subject of research was the spatial-ecological organization of the mycobiota of macromycetes. In the process of research, practical methods of direct observation from the mycocenological arsenal, theoretical-practical methods of analysis-synthesis, decomposition-composition and theoretical methods of correlating the abstract and the specific, and idealization were used. Based on the generalization of experimental data obtained in the course of practical studies of the spatial ecological organization of mycobiota of macromycetes carried out in the territory of the Botanical Garden of Belgorod State University, the principles of decomposition analysis of the structure of mycobiota of macromycetes of individual natural territorial entities are substantiated. A scheme of compositional construction of mycobiota of macromycetes is proposed, as well as a scheme in the form of a linear sequence showing the spatial ecological organization of mycobiota of macromycetes in a “pure form”: mycobiota - mycochore (mycocenosis, mycoaggregation) - mycosynusia-3 - mycene cell - mycocell.
