Tuber melanosporum, also known as black truffle, is a type of edible fungus that grows underground in the roots of certain tree species, such as oak and hazelnut. It is native to Europe, particularly in regions of France, Italy and Spain, but it is also cultivated in other parts of the world.
The fruiting body of Tuber melanosporum is round or irregularly shaped, and can grow up to the size of a golf ball or larger. The exterior is rough and covered with small pyramidal warts, while the interior has a blackish-brown color and is marbled with white veins. The aroma of Tuber melanosporum is described as complex and earthy, with notes of musk, chocolate, and a hint of garlic.
Black truffles are considered a delicacy and are used to flavor a variety of dishes, such as pasta, risotto, and omelets. They are also used in the production of truffle oil and other truffle-infused products. Due to their high demand and relatively low supply, black truffles can be quite expensive, with prices reaching thousands of dollars per kilogram.
