Collection of four mycelial samples (s1, s2, w1, and w2) of peripheral hyphal zones from L. edodes at the AC (after contact for 24 h) stage. The highly resistant (Y3334) and susceptible (Y55) L. edodes strains were grown on PDA plates that were covered with cellophane at 25 °C in a dark environment. The resistant and susceptible samples of the mycelia of L. edodes (s2, w2) were harvested after the T. atrovide strain 92-1 had made contact with the L. edodes strains for 24 h. As controls, the Y3334 strain and Y55 strain of L. edodes were confronted with themselves. The mycelial samples of resistant and susceptible L. edodes (s1 and w1) were harvested after contact for 24 h; s1 represents Y3334 vs. Y3334; s2 represents Y3334 vs. T. atrovide strain 92-1; w1 represents Y55 vs. Y55; w2 represents Y55 vs. T. atrovide strain 92-1. The red square represents the sampling location.
