Between the end of the seventeenth and beginning of the eighteenth century, the Italian sovereigns Vittorio Amedeo II and Carlo Emanuele III delighted in organizing veritable collections. An interesting episode concerns a truffle expedition that took place in 1751 and was organized by Carlo Emanuele III at the Royal House of England. During the day, different truffles were found, but they were of extremely inferior value compared to the Piedmontese ones. Count Camillo Benso di Cavour, during his political activity, used the truffle as a diplomatic means, the composer Gioacchino Rossini called it "The Mozart of mushrooms", while Lord Byron kept it on his desk so that the scent helped him to arouse his creativity. and Alexandre Dumas called it the Sancta Santorum of the table. In 1780 the first book concerning the White Truffle of Alba was published in Milan, baptized with the name of Tuber magnatum Pico (Magnatum - that is, "magnates", for wealthy people, while Pico refers to the Piedmontese Vittorio Pico, the first scholar who he took care of his classification). A naturalist of the botanical garden of Pavia, Dr. Carlo Vittadini, published in Milan in 1831 the "Monographia Tuberacearum", the first work that laid the foundations of the idnology, the science that deals with the study of truffles, describing 51 different species . The study of hypogean mushrooms was later investigated by Italian researchers and currently in Italy, and in particular in Piedmont, the best study centers reside.
