The fruiting body is more or less spherical, irregular, dark brown to black, completely covered with obtuse and acute 2-10mm wide polygonal warts, often 5 to 6-faced, finely grooved with 4-5 horizontal markings (use magnifying lens), without stem. The flesh is firm, white in the youth, then yellowish to grey-brown, marbled with branching whitish veins; its taste is very pleasant, nutty; the odour is strong and sweet, unpleasant for some people. The fertile surface is internal. It grows underground (at a depth ranging from 4in to 2 ft, which is from 10 to 50 cm deep), in deciduous woods, on a rather calcareous soil, preferably with beech or oak, also with hazel, more rarely with maple, hawthorn, wild cherry, ash, elm, pine, juniper, birch trees.
Distinctive features : Dark brown to black, irregularly hemispherical fruiting body, covered with acute, polygonal 2-10mm wide warts which are grooved (use magnifying lens); very fragrant flesh, white then grey-brown and marbled with branching white veins; found underground on calcareous soils, in deciduous woods, preferably with beech or oak. Tuber aestivum is still unreported so far in the forest of Rambouillet, and is rare, more generally speaking .
