Mushrooms growing on tree

Asked July 10, 2018, 5:29 PM EDT

I have what seems to be oyster mushrooms about eight inch diameter growing on the trunk of a tree where a large branch was removed several years ago. Should I be concerned about damage to the tree and how do I get rid of them? The tree is about 50 years old and 26 inch diameter trunk. I believe it is a type of maple. It has those 'helicopter' seeds.

Some wood rot fungi are more destructive than others. Although the presence of fungi does not mean a tree is doomed, it's important to assess the tree's health to be sure it doesn't become a hazard.

Under the circumstances it's best to ask a forester or certified arborist to inspect the tree onsite and recommend a course of action.
