Armillaria root rot: This disease affects the lower part of the tree, it is also found in other species of oak trees. The branches and roots die due to this disease. A light brown to dark brown colored mushroom is formed each year in the autumn in a few clusters at the base of the trees. It is 6 inches in diameter and its stem is ½ to 1 inch thick and can be 2 to 6 inches long. So due to this disease trees stop growing.
