Stephanospora is a genus of truffle-like gasteroid fungi in the order Agaricales. In 2014, nine new Australasian species were described from collections previously thought to represent S. flava . ^[1]

Taxonomy

Stephanospora was circumscribed by French mycologist Narcisse Théophile Patouillard in 1914 with S. caroticolor (formerly classified as a species of Hydnangium ) as the type species. ^[2]

Natural compounds

The "carrot truffle", Stephanospora caroticolor, contains the compound stephanosporin, a 2-chloro-4-nitrophenol precursor. The compound, which gives the fruitbody its orange colour, converts to the toxic 2-chloro-4-nitrophenolate when the fruitbody is injured. ^[6]
