this is not likely to be Ganoderma lucidum. G. lucidum was first collected in China on flowering plum. In Oregon, Ganoderma is relatively common, and it certainly is a Ganoderma. I’d gues Ganoderma tsugae, which grows only on Western hemlock and Sitka spruce in my experience. Usually G. tsugae has a bright red lacquerware finish on it.
