Abstract: Mycogone perniciosa MP0012 and Agaricus bisporus AS2796 were used as experimental materials, and the interactions between their mycelia of Mycogone perniciosa MP0012 and Agaricus bisporus AS2796 were investigated through confrontation culture, double culture and microscopic examination.The results of the confrontation culture test revealed that the mycelia of the two species were initially able to tolerate each other without any visually evident growth inhibition. However, both confrontation and double culture tests suggested that the volatile compounds produced by M. perniciosa eventually evidently inhibited the growth of A. bisporus and resulted in a large number of mycelial knots andfractures forming in the latter. On the other hand, the mycelia of A. bisporus had growth‐promoting effects on M. perniciosa. The infection experiment revealed that M. perniciosa could directly infected and caused an infection in A. bisporus. Observations of the fruiting body of infected A. bisporus revealed that the mycelium of M. perniciosa appeared during the early stages of infection and was responsible for stalk hollowing and gill browning. During the intermediate stage, the mycelia of A. bisporus began to shrink and crack, while the cell walls in the vicinity of M. perniciosa exhibited signs of degradation. During the final stages of infection, the mycelia of A. bisporus almost completely disappeared. So it can be concluded that this pattern of parasitism is consistent with what is exhibited by necrotrophic mycoparasites.
