The term Butyriboletus pseudoregius (Heinr. Huber), D. Arora & J.L. Frank.

Etymology –
The term Boletus is of controversial etymology: as it derives from the Greek βωλήτης bolétes, with which the Greeks called a kind of mushroom (from βωλος bólos with the meaning of gleba, clod, bush, because growing among the clods or bushy places); others instead believe that the meaning of βωλος is to be extended to the ball, since the hat of most mushrooms is globose; for some authors it derives from Bolites name with which the Romans indicated the best edible mushrooms, although originally referred to only the ova (Amanita cesarea), but soon used to call also porcini. The specific epithet pseudoregius comes from the Latin regius, royal, and from the Greek ψευδο, that is false, since it is exchangeable with the previous one.

Geographic Distribution and Habitat –
Boletus pseudoregius is a rare fungus that grows under broad-leaved trees, especially beech and chestnut.

Recognition –
This mushroom is recognized for the 5-15 cm diameter hat, fleshy, hemispheric and then flat and convex, with a dry cuticle, felted with an antique pink color – brownish pink. The pores are round, small, yellow-gold, turning blue to pressure. The tubules are long, yellow in color, then green-olive, turning to blue.

Uses and Traditions –

Boletus pseudoregius has an edibility very similar to the most known edible bolete. It can be prepared and stored in the same way as these but, we repeat, it would be better not to collect it and leave it undisturbed in its habitat.
