Hispidus Canker: Identifying Characteristics
| Identifying the injury: | Sunken lesions (cankers) on stems. On smaller branches the symptoms may appear spindle-like. Along the margins of the cankers the callus tissue is usually evident. |
| Identifying the pathogen: | Trees bear whitish-yellow to reddish brown, spongy, stalkless fruiting bodies (conks). After spores are released, the conks usually dry and turn blackish and often fall from the tree. |
| Susceptible trees: | Mostly laurel, water and willow oaks. Sometimes hickory is affected. |
