The cap colour of this massive bolete is very variable. It can be dark chocolate brown, pale brown or even coppery bronze. The cap flesh is yellow, rapidly bluing when cut or bruised. Caps are initially downy and convex, becoming flatter, smooth and shiny as the fruiting body matures. The diameter at maturity varies between 8 and 20 cm. The pores under the cap are orange turning to bright red and rusty brown with age. The spore tubes are lemon yellow turning blue when cut or bruised.
