Fungus at base of oak

Asked December 30, 2018, 11:07 AM EST

The fungus in the picture is growing at the base of a mature oak tree. What should I do? Is this an indication that the tree may fall and should be removed? The fungus is about 16 inches across.

Unfortunately, what you have there looks like a type of wood decay fungus. It is a sign that there may be decay in the heartwood of the tree, for which there is no cure. You should have the tree evaluated by a certified arborist. See the following information:
