Coniocarpon is a genus of lichen-forming fungi in the family Arthoniaceae.[1] It has eight species of corticolous (bark-dwelling) lichens.[2] This genus is distinct for its crystalline orange, red, and purple quinoid pigments in the ascomata that turn purple in potassium hydroxide solution, its colourless, transversely septate ascospores with large apical cells, and its rounded to lirellate ascomata (fruiting bodies).
The genus was circumscribed by Augustin Pyramus de Candolle in 1805.[3] The genus was rejected against Arthonia as proposed in the International Code of Nomenclature for algae, fungi, and plants in Appendices I–VII.[4] In 2014 however, Coniocarpon was resurrected by Andreas Frisch and colleagues for the Arthonia cinnabarina species complex, based on the results of molecular phylogenetics analysis, which showed that it formed a clade with the genus Reichlingia.[5] The type species of the genus, Coniocarpon cinnabarinum, had previously been designated by Rolf Santesson in 1952.[6]
