Rubroboletus satanas

Rubroboletus satanas, commonly known as Satan's bolete or the Devil's bolete, is a basidiomycete fungus of the bolete family (Boletaceae) and one of its most infamous members. It was known as Boletus satanas before its transfer to the new genus Rubroboletus in 2014, based on molecular phylogenetic data.

These squat, brightly coloured fruiting bodies are often massive and imposing, with a beige-coloured velvet-textured cap up to 50 cm (20 in) across, yellow to orange-red pores and a bulbous red stem. The flesh turns blue when cut or bruised and the fruit bodies often emit an unpleasant rotten odor.
