So there is probably Elaphomyces present in the area.
In your area Western Red cedar probable. Western Red cedar one of the very few trees which doesn’t associate with mycorrhizal fungi. So Douglas-fir probable host tree here.
After looking carefully at the sectioned Elaphomyces, I can’t even tell it is Elaphomyces. Does not appear to have visible spores. Very unusual.
So maybe (just maybe) the host is not Elaphomyces here.
