Mushroom looks old and tired now, but didn’t change much since previous photos were taken.

In regards to suggested Laetiporus

I strongly doubt it. This mushroom has been there for several weeks now. I watched it since it was much smaller and hoped when it gets bigger I will be able to nail down the species. It’s now a foot-and-half in width – fact hard to appreciate on photos since the tree is humongous. It may or may not grow a bit bigger, but the season is rolling to an end here. The whole appearance and the shape of the mushroom look different. The yellow color is a baffler – not that many species have it (apart from Laetiporus). I have a piece of the mushroom, trying to wring the spores out of it (seldom happens with polypores).

Will have to double-check on the host.

This is an extremely large tree. When I looked up to the crown to see the leaves, I was sure I was looking at Hackberry, but now looking at the photo of the bark I am not so sure.
