Truffles are a type of underground fungi that are commonly found in association with trees. These fungi have important roles in nutrient cycling and drought tolerance in their ecosystems. 

Some truffle species are highly prized as a gourmet food and are used in haute cuisine in Italy, France, and other countries. Fresh truffles are native to Southern Europe, but they have been found in many other countries as well. Truffles have a beautiful aroma and can be shaved or shredded to add a luxurious taste to a variety of dishes.
