35 strains (17 species) of mycorrhizal Basidiomycetes were cultured with Pinus silvestris seedlings. The fungi showed only slight antibiotic activity, which did not increase with seedling presence. In 12% of tests, growth of parasitic fungi was inhibited. Rhizoctonia solani was the most inhibited species.
