Tuber aestivum Vittad. is characterized by a broad ecological amplitude and geographical distribution. It is the most widespread truffle species found in Europe. Tuber aestivum is mainly harvested in natural habitats and in previously cultivated soils recolonized by ectomycorrhizal tree species. Production in orchards is less common. In this chapter, we describe the soils in which this species fructifies. Soil descriptions and characteristics were obtained from different sources and countries. The data set presented here is the largest of its kind for such a broad geographic scale. The bedrocks are mainly of sedimentary origin. The textures vary considerably from silty clayey to loamy sandy. In most of the soils, the pH is alkaline or neutral and, less frequently, slightly acidic. The soils are mostly calcareous or rich in exchangeable alkaline cations, mainly calcium. Despite the fact that they are found mostly in natural habitats, T. aestivum exhibits high potential for settling in new environments.
