I found this fungus on the base of one of my trees in my yard. I believe it to be brittle cinder fungus which, according to my research so far, is pretty serious. I want to get rid of it but I have found nothing to tell me what the best course of action would be. While losing one tree is bad enough, I'd prefer to prevent the spread of this fungus to the rest of our trees. Ideas? Thoughts? Thank you.
