Trunk may have area of rotting bark at the base. Lesions on the trunk resemble Phytophthora gummosis, clusters of mushrooms may be present at the bottom of the tree and fan shaped mycelial mats are often present between the bark and the wood.

Comments

Healthy trees are usually infected by infected pieces of wood or tree stumps which have been left in the ground after an orchard is cleared.
