The Bianchetto (scientific name Tuber Albidum Pico) is a little precious truffle, but sometimes, some larger specimens are sold mixed with white truffles with which it is often confused by nasi little experts. Less fragrant than the white truffle and is on average smaller in size. The gel is marbled by whitish and reddish-white veins on a brown-violet or reddish-brown background.

The Tuber Aestivum well known among truffle connoisseurs with the vulgar name of "Scorzone" or Black Summer, is one of the least prized truffles although it is a good mushroom. The gleba has a hazelnut color, more or less yellowish in the mature specimens, often also of a lighter color, it is furrowed by numerous whitish veins, more or less thin, branched and anastomosed.
