Interactions between the ectomycorrhizal fungus, Suillus bovinus, and saprotrophic fungi from different soils were examined in co-culture on agar plates by light and scanning electron microscope to determine the characteristics of their interactions and mutual effect of the fungi. Suillus bovinus was inhibited only by Trichoderma viride, T. hamatum, T. koningii and Hypholoma fasciculare but damage to its hyphae was rarely observed. On the other hand, with the exception of H. fasciculare, S. bovinus inhibited the growth of the studied saprotrophic fungi at distance. In the zone of interaction, colonies of saprotrophic fungi showed hyphal alterations, such as vacuolation, coagulation, and cytoplasm release; however, fungi from forest and abandoned soils showed more changes in hyphal morphology than those from agricultural soil, e.g. Epiccocum nigrum and Colletotrichum coccodes. In this article we discussed changes in hyphal morphology as a result of life strategy of fungi originating from different type of soils.
