need to see something convincing to use the genus name Piptoporus. Anything can happen, but a better closeup of the top and bottom would be helpful. It is difficult to make any determination from the photo. If you think this looks like P. betulina, try comparing your photo with others on MO. If it is P. quercinus, and in theory, it could be, it would be worth going back to get better photos if that is possible.

Compare with these obs.

Piptoporus quercinus?

Would this be better classified as Piptoporus quercinus, the oak polypore? I went with betulina simply because it looked so very very similar to all the betulina that I have seen before and I understood that quercinus was relatively rare. I didn’t realize how strongly the association with host tree defined the species.
