Is Red-mouthed bolete edible?

Boletus erythropus is generally considered edible after thorough cooking. However, it is toxic if consumed raw or insufficiently cooked, causing gastric upset. Its edibility should not be confused with highly toxic look-alikes. There are no known specific toxins, but it's believed to contain compounds that are thermolabile and break down with heat. Extreme caution is advised due to potential confusion with genuinely toxic bluing boletes. ALWAYS cook this mushroom thoroughly.
