Recognized by sight: polypore growing on downed cottonwoods and possibly a deciduous oak. I know next to nothing about unusual polypores, so take this identification with a dose of salt, but it is the best I have been able to come up with so far. In addition to size and shape , factors in identification include growth on dead cottonwoods, densely white tomentose, furry textured pileus, angular asymmetrical pores, growth habit and coloration. There are more reports of gallica in the Sacramento valley and California in general, but gallica should be darker. The pale tan pore surface, whiter pore interior, and pale pileus with rusty orange margin would make this trogii instead. It fits the referenced key well, and seems closer to pictures of trogii than any other polypore pictures I have seen so far. Thoughts welcome.
Used references: Annotated key to the mushrooms of the Pacific Northwest, mushroom observer
