We have a 10 year old pagoda dogwood tree in our backyard that has a mushroom growing near the base of the tree (see attached pictures taken July 4th). A family member that has an expertise in mycology, but is not an arborist, suggested that the mushroom may be growing because the tree has a damaged root structure and that the damage may ultimately kill the tree. An identical mushroom grew in the same spot two years ago. Is this enough information for you to form an opinion and give us some advice? Thank you in advance.
Mushrooms growing on the dogwood's roots, could indicate that the roots have been damaged or begun to decay. However, if this particular fungus is growing on organic matter in the soil that just happens to be adjacent to the roots, its presence is unlikely to indicate anything about the tree's health.
