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

Example of the different effects of FR fungi on vegetation, considering either the Hydrophobicity or the Phytotoxicity hypothesis. N: Nutrients derived by plants decay; S: Phytostimulants released by the fungus; H: Hydrophobicity produced by the fungal biomass above a threshold level; T: Phytotoxic compounds released by the fungus. Bottom row represents the net effect on vegetation of the combination of positive (N, S) and negative (H, T) conditions.
