That is polypore squamosa (dryad's saddle, pheasant's back), the young nubby ones are edible and tasty, but as they get older they get mealy and weird.
Lived yet another year eating wild mushrooms and other foraged goodies. To those that came out to any events I spoke at this year, thanks! The season is coming to an end in the area - see you next year.
Spore prints are always handy, and one of many ways to identify. Always good practice. Polypores do drop spores, typically through tubelike structures under the cap. There is a gilled polypore (lenzites betulina/gloeophyllum sepiarium) but it has no culinary use.
