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...

Treatments consisted of dual cultures of E. purpurascens and xylophagous fungi on box elder (Acer negundo) wood blocks.

When E. purpurascens was allowed to colonize wood blocks before the introduction of the xylophagous fungus, dry weight loss was significantly reduced in all instances.

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.
