Inonotus hispidus |
| USDA Forest Service. 1979. A guide to common insects and diseases of forest trees in the northeastern United States. Northeast. Area State Priv. For., For. Insect and Disease Management., Broomall, PA. p. 123, illus. |
Inonotus hispidus (formerly Polyporus hispidus) causes localized defect in black ash and oak. Because this fungus is associated with branch stubs, frost cracks, or other wounds, the decay is mostly in the upper portion of the trunk. In southern oaks the fungus also commonly causes a canker rot. The rotting wood becomes yellowish-white and spongy. The conk is shelf-like and up to 10 inches wide. The undersurface is golden brown. The conk is an annual, formed in the fall and borne for only a few months.
