White fungus on maple trunk #705660

What to do to treat this maple? Three weeks ago I noticed it’s leaves weren’t as well developed, now this fungus came up quickly on the trunk. Spongy, penetrates the bark. Would like to treat the tree, but this isn’t looking good to me. I have several other maples, so I’d like some guidance if this is likely to affect them too. No particular past or recent trauma to the tree.

Hello,
This looks like some sort of rot, perhaps sapwood rot. I recommended you hire a certified arborist to give an exact diagnosis. This is a professional who has taken training in care, diseases, pests and passed certification tests. He/she will come on site and give a complete diagnosis and a plant care plan.
