Xanthoparmelia mexicana
Xanthoparmelia mexicana, commonly known as the salted rock-shield,[2] is a foliose lichen in the family Parmeliaceae. It grows in 4–10 cm diameter rosettes of gray-green to yellow-green lobes in arid climates all over the world.[3] It grows on acidic rock and soil, in open and arid habitats all over the world.[3] It may loosely cling to the substrate (adnate).[3] It grows in 4–10 cm diameter rosettes of lobes.[3] The lower surface is pale to medium brown.[3] Apothecia are uncommon, with cinnamon to dark brown discs, smooth margins, and no pruina.[3] Lichen spot tests are negative for the upper cortex (K-, C-, KC-, P-). For the medulla they are K+ yellow to dark red, C-, KC-, and P+ orange.[3] It produces secondary metabolites including usnic acid and salazinic acid.[3] In the Sonoran Desert, it may be the most commonly found member of its genus.[3]
