Looks like Maitake. https://en.wikipedia.org/wiki/Grifola_frondosa
That is not enough to say it is or is not in trouble. It is worth a better look by somebody who knows what they are looking at. Expect to pay for an evaluation....don't ask somebody who is bidding to do the removal - of course they think it needs removed (as immediately as they can schedule it). See if there is a Tree Risk Assessment Qualified Arborist in your area: www.treesaregood.com
Root and butt rot fungus is no joke, get it looked at. We do know that severity of decay can be estimated by number, size & distribution of basidiocarps around the tree.

When a fungus attacks an ash, dogwood, maple, oak, sycamore, or walnut tree, it defoliates and disfigures the tree, significantly diminishing its appearance. During the spring, watch for twig cankers, twig dieback, defoliation, and leaf blotching.
Use proper fertilization and fungicide applications as needed during the spring, and remove and rack the dead leaves in the fall. You can also prevent anthracnose by watering appropriately, maintaining proper pruning, and planting resistant cultivars.

You are certainly better off feeding trolls than fertilizing fungus
