There is no common name for this one as far as i’m aware. Probably because it’s just a bland white polypore, which is not so easily distinguished from other plain white & boring polypores. It looks somewhat like Trametes versicolor, in that you can make out some rings, or banded zones on the cap. But it is devoid of color. It’s also thicker and woodier than Trametes versicolor. But, it does have similarly sized white pores on the under side. It’s cap surface is also similarly fuzzy, to Trametes veriscolor and Trametes betulina.
