“I noticed my maple tree has a growth on the base. There were red bugs near the base a week or so ago and I sprayed with a safe insect spray. Today I see this growth that looks like an inverted mushroom with red on it. I also see some ants today. I just saw a picture online https://www.melindamyers.com/articles/mushrooms-growing-at-the-base-of-maple-tree So think I know what it is. "The growths on your maple tree are the fruiting bodies of a shelf fungus." What can I do about it? And is it harmful to leave? Can I break it off? thanks !!
