The dark summer truffle (uncut truffle, Tuber aestivum var. uncinatum (Chatin) I.R. Hall, P.K. Buchanan, Wang{?} Cole), also known as the Burgundy truffle, occurs throughout Europe, in habitats of wide ecological value and on numerous tree species, which is why it is extremely interesting for plantation cultivation. It is naturally distributed from North Africa in the south (Atlas Mountains, Morocco) to southern Sweden in the north (Gotland), and from Portugal in the west to the Caucasus in the East. It grows fruiting bodies from 50 (in colder regions) to 1,600 (in warmer regions) meters above sea level. Some authors state that it can bear fruit throughout the year, while aromatically there is no difference between a summer truffle and an untrimmed truffle.
