Cherry Tree Gummosis

Description:

Cytosporina gummosis discolors cherry tree bark and produces amber-colored ooze. Twigs and limbs die suddenly even though the leaves are still attached. Cankers, which are raised areas filled with fungus, may form, or the disease may cause sunken, wet-looking lesions. If you find curly orange threads protruding from the bark, the likely cause is Cytosporina gummosis. Spores enter through wounds from insects or mechanical injury.

Notes:

Found on the North side of a 10 inch dia. Black cherry tree.
