摘要：

Aspen that bear a certain type of black gall have a lower incidence of heartwood rot (caused by the fungus Phellinus tremulae) than do nearby non-gall trees. Efforts to determine the chemical nature of this black gall effect are described. The metabolites of some fungi associated with the black gall (Phoma etheridgei, Stachybotrys cylindrospora), and of the rotting fungus Phellinus tremulae, are described. Extracts of the black gall tissue have a very high concentration of benzoic acid acid it is suggested that the benzoic acid may play a role in the protection of the galled trees.
