Stephanospora is a genus of gasteroid fungi in the family Stephanosporaceae (order: Russulales). As of September 2015, Index Fungorum lists six species in the genus;[1] nine new Australasian species were described in 2014 from collections previously thought to represent S. flava.[2]

Scientific classification

Pat. (1914)
Type species
Stephanospora caroticolor
(Berk.) Pat. (1914)


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.[3]


Natural compoundsEdit

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.[7]
