There are a variety of black truffles but the only real one is the Tuber Melano spore, characterized by its round shape, coal-black appearance and unique scent of earth, mushrooms or nuts.
The inside of these truffles is a brownish black with visible white veins (except towards the end of the truffle season). Known as Perigord truffles, they are generally harvested in the Perigord region of France or Spain. This versatile treat can be enjoyed raw, added to sauces or used to spice up chicken dishes. With its obscenely high prices, the Tuber Melano spore is an ideal target for fakers who try to sell imitations. Less expensive types are often colored and passed off as the real deal by savvy swindlers.
