Genea is a genus of truffle-like fungi in the family Pyronemataceae. There are about 32 species in the genus that occur in North America and Europe.

With the help of a trained dog, scientists discovered 2024 that there are probably still some non-descript species. Furthermore, these truffles seem to disappear completely from the fir-dominated forests for years after a forest fire.

The genus was circumscribed by Italian mycologist Carlo Vittadini in 1831.

The genus name of Genea is in honour of Carlo Giuseppe Gené (1800 - 1847), who was an Italian scientist (Zoology) and Professor of Zoology at the Turin Museum of Natural History.
