Truffle

Truffle (fungi) – Wikipedia, the free encyclopedia
The record price paid for a single white truffle was set in December 2007, when Macau casino owner Stanley Ho paid US$330,000 for a specimen weighing 3.3 lb, discovered by Luciano Savini and his dog Rocco. One of the largest truffles found in decades, it was unearthed near Pisa and sold at an auction held simultaneously in Macau, Hong Kong and Florence.
