Mushrooms growing near a tree may be decomposing organic material in the soil, but certain fungi can also indicate root or trunk decay. Their significance depends on the fungal species, location, and condition of the tree.
Fungal structures emerging directly from the trunk or major roots deserve particular attention because some wood-decay fungi can affect structural strength. However, the presence of mushrooms alone does not establish that a tree is unsafe.
Homeowners should avoid disturbing suspicious fungal growth before it can be identified or documented. Photographs of the mushrooms, their location, and any related tree symptoms may help during an inspection. Large trees near buildings or occupied areas should be assessed promptly when decay is suspected.
