Schistophoron aurantiacum is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae.

[1] Found in Costa Rica, it was formally described as a new species in 2007 by lichenologists André Aptroot and Harrie Sipman.

The type specimen was collected by the second author from Carara National Park (Puntarenas Province), where it was found along a stream in a partly disturbed primary forest dominated by an understory of the shrub Erythrochiton gymnanthus.

Schistophoron aurantiacum contains lichexanthone, a lichen product that causes the thallus to fluoresce yellow when lit with a long-wavelength UV light.

The orange colouring of the thallus results from an anthraquinone compound that has a K+ (deep violet red) chemical spot test.
