Agrocybe Aegerita (Pioppino)

It's one of the best known and loved mushrooms by Italians since ancient Rome.
The Pioppini, even after harvesting, can last a long time if stored in the refrigerator, keeping their organoleptic qualities unaltered.
As most sliced mushrooms, these lend themselves well to being cooked in combination with egg.
Alternatively, if they’re young and still tightly closed, they are excellent for preserving in oil.
