Mushrooms grow from dying organic material (your bark)
There is no worry here, just growing mushrooms

Mushrooms almost never kill a tree, but when they’re growing on the trees, it’s usually a bad sign. Here, you’re totally fine. Fungus doing what it do, turning mulch into soil.

It does look like armillaria aka honey mushroom. It took out 3 maples in my yard over a decade, some tree species are resistant though. There are also different species of honey mushroom and they vary in how aggressive a parasite they are, there’s a key to identify them here.

There is fungus among us pretty much everywhere you are.
Armillaria most likely feeding on dead roots. Either old dead roots or that tree is slowly dying.
Regardless of species ID for fungus, your tree is poorly planted in a crappy spot, and too much mulch.
Hire an arborist to actually come out and give you a full assessment.
