That seems exactly right. Its listed as mostly growing on Oaks and is parasitic.

Thank you
We get these on the pin oaks lining our city's streets and it's the harbinger that the old tree will need to be cut down and replaced. Or that it's going to fall in the foreseeable future.
Could also be an old Laetiporus but I’m not sure.
