Edible, underground fungus in the genus Tuber (class Ascomycetes, division Mycota), prized as a food delicacy since antiquity.

Native mainly to temperate regions, truffles flourish in open woodlands on calcium-rich soil. The different species range from pea-sized to orange-sized. Truffles usually are associated with tree roots and are found up to about 1 ft (30 cm) below the soil surface. Experienced gatherers occasionally detect mature truffles by scent or by the morning and evening presence of hovering columns of small yellow flies, but more often with the help of trained pigs or dogs. The truffle is important in French cookery, and truffle gathering is an important industry in France. Truffles are among the most highly valued foods in the world. False truffles (genus Rhizopogon) form small, underground, potato-like structures under coniferous trees in parts of North America.

English truffle (Tuber aestivum).

      edible, subterranean fungus prized as a food delicacy from Classical times. Truffles are in the genus Tuber, order Pezizales (phylum Ascomycota, kingdom Fungi). They are native mainly to temperate regions. The different species range in size from that of a pea to that of an orange.

      A section of a young specimen shows a whitish homogeneous flesh that with age becomes a rich dark colour showing a lighter marbling. Truffles flourish in open woodland on calcareous soil. They are saprophytes, usually associated with the roots of trees, possibly in a mutually beneficial association (see mycorrhiza). The spores of Tuber are large; from one to four may be seen in a spore sac, or ascus. (These, the first ascospores to be observed, were described by the French botanist Joseph Pitton de Tournefort (Tournefort, Joseph Pitton de) in 1701–11.)

      The most valued truffle in French (France) cookery is the Périgord (T. melanosporum), which is said to have first gained favour toward the end of the 15th century. It is brown or black, rounded, and covered with polygonal warts having a depression at their summit; the flesh (gleba) is first white, then brown or gray, and when mature becomes black with white veins having a brown margin. The odour is well marked and pleasant. The main French truffières (truffle grounds) are in Périgord and the département of Vaucluse, though truffles are gathered throughout a large part of France.

      The truffle industry is an important one in France, and about one-third of the gatherings are exported. The French government undertook the reforesting of many large and barren areas, for many of the best truffle regions become productive by the planting of trees, particularly oaks. Because truffles often occur at depths of up to about 30 centimetres (12 inches), it is difficult to detect them unaided. Truffles, when occurring near the surface of the ground, crack it as they reach full size, and experienced gatherers can detect them. Furthermore, in the morning and evening columns of small yellow flies may be seen hovering over a colony. Occasionally an individual is sufficiently sensitive to the scent of truffles to locate them, but truffle hunting is usually carried on with the aid of trained pigs and dogs.

      Although truffles are much desired as food, direct cultivation of truffles for commerce is difficult. Calcareous ground is dug over and acorns or seedlings planted. Soil from truffle areas is usually spread about, and the ground is kept in condition by light plowing and harrowing. After three years, clearings are made and the trees pruned. If they are to appear, truffles do so only after about 5 years; gathering begins then, but is not very profitable until 8 or 10 years have passed. The yield is at its maximum from 5 to 25 years later.

      The English truffle, T. aestivum, is found principally in beech woods. It is bluish black, rounded, and covered with coarse polygonal warts; the gleba is white when immature, then yellowish, and finally brown with white branched markings.

      Truffles are rare in North America, being found most often in Oregon and California. False truffles (genus Rhizopogon, order Boletales, phylum Basidiomycota) form small, underground, potato-like structures under coniferous trees in parts of North America.
