I have been hunting mushrooms just in the last few months and have begun to notice these in my local woods. They are thick and rubbery. The caps have pale indistinct bands of brown and cream, no velvet, with lumpy centers in the semi-circle. I thought they might be trametes gibbosa, but they don't have elongated pores on the bottom! They're normal round pores. I find them on downed trees, usually oaks.
