Large Japanese Maple Has Limb With Mushroom Like Growth

Question From: M. Dobson - Skiatook, Oklahoma, United States
Q: My large Japanese maple has a limb with mushroom looking growths. It looks the same as I have seen on trees that were dying. Should I cut off the limb? Can it be treated? Thanks

A: Take a picture of the growth to a good independent nursery or garden center that sells these trees for an accurate ID and recommended control. Best And Happy Yardening, Nancy
