My great aunt's old place had an old sawmill on the property, one that my great uncle worked on back in the 30s. They would grow plentifully in that old saw dust. This was Ava, Missouri. Man those things were delicious.
ours are very dark in Washington. they tend to grow in places that burnt.... typically east of the cascade mountains. they are hard to spot. I like chantrelles as they are so bright they are easy to pick out visually in the woods
