I will have to get my book out, but it could be "chicken of the woods" an edible, mushroom that is considered pretty good. If if is it will probably come back every year for several years about the same time of yr.
Edit: here is a link:
Laetiporus sulphureus: The Chicken of the Woods (MushroomExpert.Com)
Edit 2: That one did not mention that it was edible, but this one does:
