A rare, oak-associated bolete with a sticky, shiny, deep bright-red cap, red pores that bruise dark blue, and a yellow stem with fine red flecks and no net. It is red-listed in several European countries. In North America it has been found in North Carolina, Iowa and Illinois, and it is also reported from Belize. Whether New World collections match the European species genetically has not been tested.
Edibility not documented. It is a red-pored, blue-staining bolete, a group that includes poisonous species, and it is rare and red-listed in Europe. Not recommended; do not collect it for the table.
