Fungal Gummosis
(fungus - Botryosphaeria dothidea): The fungus enters through wounds or
lenticels on lower parts of scaffold limbs and the trunk. Older infection sites
typically exude gummy resin. Necrosis is associated with infection but usually
is restricted to the area just under the bark. Over time the bark develops a rough
texture. Trees can recover somewhat if infection is not severe. Stressed trees
are damaged the most.
