Figure 1
From: Process based modelling of plants–fungus interactions explains fairy ring types and dynamics

The 5 types of fairy rings observed in nature. On the left, graphical representation of the mycelium distribution in the soil, position of the fungal carpophores, and effect on vegetation; in the middle, dashed lines representing fungal front on real cases pictures of all types; on the right, expected spatial transects of plant and fungal biomass. The two arrows shown for Type 1 figures represent the general direction of expansion for all fairy rings. Pictures from Maurizio Zotti.
