Kalaharituber is a fungal genus in the family Pezizaceae. It is a monotypic genus, whose single truffle-like species, Kalaharituber pfeilii, is found in the Kalahari Desert, which spans the larger part of Botswana, the east of Namibia and the Northern Cape Province of South Africa.
The fungus was first described scientifically in 1895 by German mycologist Paul Christoph Hennings as Terfezia pfeilii. It was moved to its own genus in 2005 by James Trappe and Varda Kagan-Zur.
Fruiting bodies can be up to 12 cm in diameter. These weigh approximately 200 grams, although larger rains (which affect weight) can cause them to weigh twice as much. These fruits grow close to the surface, which causes surface cracks on the ground above after rains. These fruiting bodies can occur as much as 40 cm away from the
