The lower surface is pale brown to brown. ^{[2] [3]} Xanthoparmelia ajoensis is a member of the Xanthoparmelia mexicana group, a complex of similar species that differ mainly in their secondary chemistry. ^[4]

Habitat and range

Xanthoparmelia ajoensis is found in the North American southwest including the US states of Arizona, ^[5] California, ^[6] Colorado, and New Mexico and the Mexican states of Sinaloa and Sonora. ^[7]

Chemistry
