The Tuber Melanosporum, commonly called the Pregiato Black Truffle, also known as the Black Truffle of Norcia and Spoleto, thanks to its specific flavor and aromatic scent is considered by the French as precious as the White truffle. It is eaten preferably after short cooking. The gleba is black-brown tending to violet or reddish, with thick and thin whitish veins, with well-defined contours and accompanied by two brown bands, translucent on the sides.
