Tuber Borchii vitt. Bianchetto Truffle

Tuber borchii Vittad. 1831 [= *T. albidum* Pico 1788, = *T. albidum* Bulliard 1791], commonly known as the *bianchetto* truffle (*bianchetto*, *marzuolo*, *Caciola*). The Latin name was coined by Vittadini in honor of the Polish naturalist Michel Jean De Borch, who described the truffle's morphological and organoleptic characteristics in his 1780 book, *Lettres sur les truffes du Piemont*. The scientific name of the synonym, *T. albidum*, alludes to the light color of the peridium. The common names refer to the color of the peridium and the month during which the fruiting bodies mature and are harvested.
