Tuber mesentericum, the black truffle of Lorraine, is an edible species that appears a few centimeters below the surface of the soil, in shady places and in lime-rich soils. The aroma of Tuber mesentericum is very intense, reminiscent of phenol or iodine and weakens when exposed to air. The taste of Tuber mesentericum is special, intense and reminiscent of almond. It is considered by some to be similar to Tuber aestivum but stands out from the strong phenol taste.
