Extract from Wikipedia article: Xanthoparmelia mexicana, commonly known as the salted rock-shield, 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.
Xanthoparmelia mexicana is a foliose lichen species characterized by its yellow-green to greenish-gray thallus, lobes 2-5 mm wide, and apothecia that are immersed to slightly raised. In East and Central Texas, it typically grows on trees, shrubs, and rocks in open woods and along roadsides, often in areas with full sun to partial shade. It is commonly found on species like oak, cedar, and mesquite, and can tolerate a range of soil types and moisture levels. The lichen's distribution in this region includes the Edwards Plateau, the Blackland Prairie, and the Piney Woods ecoregions.
