In food

They are technically edible but they don’t have the greatest texture or taste and as they are quite rare, so they are probably best left alone.

Known hazards

None known.

Potential lookalikes

Other Bolete’s, especially the Red Cracked Bolete (Xerocomellus Chrysenteron), but the red cracked bolete have a completely red stem and tend to show their red flesh through the cracks on the cap.
