Interaction between Epicoccum purpurascens and xylophagous basidiomycetes on wood blocks
Epicoccum purpurascens, a component of the bark micromycota, was evaluated as a potential biocontrol agent for three decay-causing hymenomycetes frequently found in Buenos Aires city trees, Ganoderma platense, Inonotus rickii and Rigidoporus ulmarius. Treatments consisted of dual cultures of E. purp...
