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] 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] 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.
