Edibility or toxicity Inedible due to its toxicity mostly constant. observations It is a beautiful bolete by bright colors, from red blood pore all'acceso contrast of the lattice with the bottom of the stem. Similarities and Varieties Possible confusion with Boletus rhodopurpureus occur, but this was most evident in the hat reddish flesh and tacking to the blue also on the stem. Boletus Satanas is distinguished by the color change discontinuously and are common on the stem, for the most massive and behavior for the particular smell emanating. Other possible confusion can occur with Boletus legaliae and Boletus rubrosanguineus but even in these cases, the color change only present in the hat in Boletus rhodoxanthus helps in the determination.
