The interaction of the fungus Lentinus edodes was tested in relation to some pioneer species of wood-decaying fungi colonising oakwood in the same conditions. The tests were performed with some steroid species of fungi occurring very often and almost always present in the stands and storages. The investigations were undertaken in mixed cultures and the interaction of fungi was defined during the approaching of the growing mycelial fronts of the competing fungi. The indexes of sensitivity of individual species in the mixed cultures, as well as the reaction types of the pairs of antagonistic fungi, were determined. The appearance of inhibition zone, slowing of growth, stimulation of growth or collapse of hyphae was observed. The results show that L. edodes always formed an inhibition zone and stopped growing before the contact with the opposite species, although in some cases the growth was slowed down and sometimes, at the beginning, even stimulated. This shows a significant antagonism with the tested steroid fungi and represents the limiting factor for the dominant physiological activities and for the development in the same medium. In practice, this phenomenon could be significant from the aspect of the success of inoculation of thinner oak roundwood or branches by the fungus L. edodes in the aim of producing of fruiting bodies for food or pharmacy.
