⚠️ Toxic look-alike
Never eat this mushroom unless you are certain it is not its toxic look-alike.
Satan's bolete, which is toxic, looks very much like the red and yellow bolete: it has no pink on the cap, a less marked net on the stem, and blues more evenly. Have every harvest checked by a pharmacist or a mycologist.
If in the slightest doubt, leave it. If you feel unwell after eating it, even several hours later, call Poison Control (1-800-222-1222) or 911.
