How to Identify a Truffle

Know the type of trees that truffle grows under. Truffle can be found below ground near chestnut, hazelnut, oak, elm, pine, willow and poplar trees. They attach to the roots of the tree. You will never find truffle under cedar or maple trees. Truffle also grows in various parts of the world such as Italy, Turkey, Croatia, France, China and North Africa.

Look for signs that truffle are under the trees. Look for a specific insect, the suillia fly. This fly lays eggs where truffles grow, above ground near the bottom of the tree. You will see the insect flying close to the ground where the truffles grow. You also can look around the tree for evidence of an animal scratching at the dirt. They may smell the aroma of the truffle, but were not successful in pulling it out. You also can clear away any litter around the tree to see if any are coming through the soil.

Notice how far down truffle can grow beneath the tree. They can grow as little as one inch below the soil to five feet deep from the base of the tree.

Feel the hard shell of truffle. All truffles have a hard shell to protect it. It can be smooth or lumpy. They are potato shaped and are no larger than golf balls. The summer truffle is one of the lightest and smallest, weighing up to 30 grams. The white truffle can weigh up to 500 grams being one of the largest.

Recognize the different coloring of truffle. White truffle is cream or light brown with white markings while the black truffle is black with white spots. Others can be reddish, yellow or beige.
