Boletus aereus

Boletus aereus is a bolete, an edible mushroom frequently consumed in the Basque Country and Italy. Known as ontto beltza in Basque, porcino nero in Italian, tête de nègre (negro’s head) in French and Queen bolete in California, it is well known in southern Europe for its culinary qualities that make it the king of boletus, even more appreciated than Boletus edulis.

Description
The height of this boletus is 15-20 cm, broad at maturity; specimens of 40 cm have been found in some cases. The cap is dark brown and the ringless stalk is 6-10 cm high, usually shorter than the cap diameter. The pores are greyish white when young, then becoming yellow.

Distribution and habitat
Boletus aereus is found mainly in central and southern Europe, being rare in colder climes such as England, and also in Western North America, where it is also uncommon. Mushrooms are found in summer and autumn.
