Found in Europe, and common in central Italy, the truffle was described as new to science by Italian mycologist Carlo Vittadini in 1831.

[2] The truffles are roughly spherical to irregular in shape, and typically measure 0.5 to 2 centimetres (1⁄4 to 3⁄4 inch) in diameter (rarely are they greater than 5 cm or 2 in).

Warts on the fruit body surface are low, so that the truffle appears fairly smooth.

[1] It has an intense garlic-like odor similar to the Italian white truffle (Tuber magnatum).

[3] Host plants of T. macrosporum include poplars, hazel, linden, and oaks.
