NW Florida. Not sure I see it year-round, but it’s super common. Always grows on dead trees but I’ve not noted what species it likes. Supper common. When it’s fresher the color is intense. This stuff has started to dry up.
I’d give iNaturalist a go:

If Stereum doesn’t check out you could take a look at Plicatura.
