A new hyperparasitic fungus, Cladobotryum amazonense, with potential for control of fungal pathogens of cocoa
Cladobotryum amazonense sp.nov., a hyperparasite of the cocoa witches' broom fungus, Crinipellis perniciosa, and other agarics in Amazonian forests, is described. The mycoparasite overgrows host basidiocarps and physically prevents normal hymenial development and spore dissemination. In addition, it produces and extracellular, heat-stable metabolite which induces plasmolysis of basidiospores and is toxic in vitro to a range of fungal pathogens of cocoa. Field application of the toxin protects cocoa tissues from infection by C. perniciosa and Phytophthora palmivora
