Terfezia (Berber: Tirfas) is a genus of truffle-like fungi within the Pezizaceae family. Terfezia species are commonly known as desert truffles. Some authorities consider this the type genus of the family Terfeziaceae,[1] although phylogenetic analysis suggests that it nests within the Pezizaceae.[2] The Dictionary of the Fungi (10th edition, 2008) suggests that the genus contains 12 species.[2] A recent (2011) publication used molecular analysis to show that the American Terfezia species had been incorrectly classified, and moved Terfezia spinosa and Terfezia longii to Mattirolomyces and Stouffera, respectively; as a result, no Terfezia species are known to exist in North America.[3]


As of December 2015, Index Fungorum accepts 34 species in Terfezia:[4]
