Connorstictic acid is an organic compound in the structural class of chemicals known as depsidones.

[1] Its structure was published in 1980 following spectral and elemental analysis of the compound purified from the lichen Pertusaria pseudocorallina.

[2] The following year, John Elix and Labunmi Lajide corroborated the structure by synthesising it in several steps from the precursor norstictic acid.

[4] Connorstictic acid is a member of the class of chemical compounds called depsidones.

[5] Lichen genera from which connorstictic acid has been isolated include Bryoria,[6] Buellia,[7] Cladonia,[8] Cratiria,[9] Diorygma,[10] Graphis,[11] Paraparmelia,[12] Parmotrema,[4] Pertusaria,[2] Usnea,[13] and Xanthoparmelia.
