Brief Description: [See More | Edit]

Entoleuca mammata is an Ascomycetous diffuse canker-causing pathogen of Populus tremuloides1,2. It . It is still unclear as to how Hypoxylon canker enters trees. Insects and birds have been found in association with infection. The round headed borers Saperda inornata and S. calcarata (poplar borers), and Obrea schaumii 1. Telamona tremulata (aspen treehopper), Magicicada septendecim (periodical cicada), Tibicen linnei (dogday cicada), and woodpeckers also create wounds that may serve as infection courts1.

The fungus produces black perithecial stroma 2; the perithecia have been likened to human mammary glands which is where it gets its name.

E. mammata may infect up to 90% of trees in individual stands2. It has infected up to 10% of the aspen in the Great Lakes region of the United States and can create a loss of one-fourth the timber annually2.
