Serusiauxia

About

Serusiauxia is a monotypic fungal genus in the family Pyrenulaceae. It contains a single species, Serusiauxia inexpectata, a corticolous (bark-dwelling), crustose lichen found in Mauritius. Serusiauxia is morphologically distinct within the Pyrenulaceae due to its sorediate thallus and chemistry involving gyrophoric acid, a combination of characteristics that is not observed in any other Pyrenulaceae genera.
