The Terfeziaceae, or desert truffles, is a family of truffles (Arabic: كمأ Kamā') endemic to arid and semi-arid areas of the Mediterranean Region, North Africa, and the Middle East, where they live in ectomycorrhizal association with Helianthemum species and other ectomycorrhizal plants (including Cistus, oaks, and pines). This group consists of three genera: Terfezia, Tirmania, and Mattirolomyces. They are a few centimetres across and weigh from 30 to 300 grams (1-10 oz). Desert truffles are often used as a culinary ingredient.

Family description

Terfeziaceae Feb 11 Photo Brief

Fruit-bodies (ascomata) are large, more or less spherical to turbinate (like a top), thick-walled, and solid. The asci are formed in marbled veins interspersed with sterile tissue. The asci are cylindrical to spherical, indehiscent (not splitting open at maturity), and sometimes stain blue in iodine. Ascospores are hyaline to pale brown, spherical, and uninucleate.

Habitat and ecology

Desert truffles, as the name suggests, predominantly grow in the desert. They have been found in arid and semi-arid zones of the Kalahari desert, the Mediterranean basin, Syria, Iran, Iraq, Kuwait, the Sahara, Saudi Arabia, Qatar, Libya, Spain, Greece, Cyprus, Hungary, Croatia, and China. It is commonly said that they are formed where lightning strikes the desert sands, since they are not the most common of fungi (thus justifying their cost).

Culinary use and commercial importance

Desert truffles do not have the same flavor as European truffles, but tend to be more common and thus more affordable. Forest truffles (Tuber genus) typically cost $100 per kilogram, and Italian truffles may sell for up to $2200 per kilogram, while Terfezia truffles sold as of 2002 in Riyadh for $80 to $105 a kilo, and in recent years have reached, but not yet exceeded, $270.

In Saudi Arabia, there are two varieties; khalasi are oval with a black skin and a pinkish-ivory interior, and zubaidi have a cream colour but are generally more expensive.

In oceanic countries, there is some confusion regarding the desert truffle, as the yam is often referred to as the common desert truffle as well.

  • Terfezia leptoderma
  • Terfezia terfezioides - phylogenetic analyses based on nuclear rDNA sequences strongly suggest that this species be reassigned to the original monotypic genus Mattirolomyces.
