One can find many edible boletes near cities like Seattle, Vancouver and Portland but boletes fruit in greater abundance in the forests throughout Washington, Oregon, and BC. There are many bolete species however foragers focus on only a small number of them

What is a bolete?

There are a few ways that a mushroom might be categorized as a bolete. The most commonly used characteristic is a spongy, porous underside of the cap that can be removed easily from the rest of the flesh.

Another group of mushrooms known as polypores also have pores however these cannot be easily removed from the flesh. Polypores are typically more leathery or woody than the fleshy boletes

When can you find boletes in Washington and Oregon?

Boletes are fruit most abundantly in the fall with the return of the autumn rains. Boletes begin to show up in the warmer spring months and will increase in abundance until late fall as snow returns to the mountains.

FAQ

Are all boletes edible?

No, but there are a lot of edible species. The red-pored bolete Rubroboletus pulcherrimus is the only species known to have killed someone in Washington state.

Why do some boletes bruise blue?

Some mushrooms in the Psilocybe genus bruise blue due to a compound called psilocybin. Boletes do not contain psilocybin and their blue bruising is related to other compounds that oxidize when the tissue is damaged. Blue bruising does not tell us anything about toxicity either. It is just a characteristic that some mushrooms have, and others do not which can be useful for identification.
