Hey there!
I seem to have found an answer with the species Lenzites betulina.
Let me know if the images from these websites match.

I have an excerpt below:
The other Turkey Tail doppelganger is one of the more unusual polypore fungi, the multi-colored gill polypore, Lenzites betulina. Fungi in the family Polyporaceae are commonly known as polypores, as they have many (poly) pores, which are actually the openings for the spore-bearing tubes that extend from the underside of the cap. The multi-colored gill polypore, as the common name suggests, has what appear to be gills on the underside of the cap (like the ubiquitous gilled mushroom). However, the gills are not the same as the true gills of a normal mushroom in that the spore bearing basidia are not connected directly to the sides of the gill surface. Rather the “gills” of L. betulina are in reality a radial arrangement of tubes and pores. Inspection reveals that the “gills” are very tough and leathery, like the polypore to which they adhere. The real Turkey Tail can thus be fairly easily identified in the field. One need only find a polypore with limbate, concentric rings and turn it over. If it has pores, it is a Turkey Tail.
