Abstract. Truffles are micoritic mushrooms that grow on the fine roots of trees (beech, oak, hazel, hornbeam, linden etc.) They are the only mushrooms that grow below the earth’s surface. In order to harvest them, specially trained dogs are used. Furthermore, due to the fact that their fruit-body is formed in the first 10-20 cm of the soil, the soil characteristics are extremely important for determining truffle areas. This article presents the main characteristics of soils where the black truffle (Tuber aestivum), white truffle (Tuber magnatum) and black Perigord truffle (Tuber melanosporum) appear

Key words: truffles, Tuber aestivum, Tuber magnatum, Tuber melanosporum, soil, pH, CaCo3.
