An underground fungus, truffles grow near the roots of certain trees such as oak or holm oaks. Truffles do not come into contact with the roots of the tree, but joins them through an imperceptible mycelium. Trees and truffles share a symbiotic relationship, they are linked to one another.
They are often found up to 20 cm deep in the soil and so deeply rooted in the earth that it takes a dog’s nose to be able to extract the truffle. Without their specially trained dogs, it would be impossible to find them at the optimum moment of ripeness.
