Notes: Any ideas? Growing on an oak log. Gills appear whole at margins then become toothy.

It looks too ‘chunky’ for Lenzites. Also the top of the cap should be zoned and tomentose like Trametes hirsuta. The ‘teeth’ and thick body leads to Daedalea quercina which can be separated fro Lenzites by the tips of the hyphae in the ‘gills’. In Lenzites the tips of the binding hyphae are pointed and long, so they resemble a sword.
Could be Lenzites, take a look and see. See if the fruiting body is fairly tough and slightly rubbery, and hard to peel of the wood. There are other polypores that dev. “gills”, but those tend to have more randomized gill structures. But Lenzites would be my first guess (but only a guess).
