Common name: common greenshield lichen.
Extract from Wikipedia article: Flavoparmelia caperata, the common greenshield lichen, is a medium to large foliose lichen that has a very distinctive pale yellow green upper cortex when dry. The rounded lobes, measuring 3–8 mm (0.1–0.3 in) wide, usually have patches of granular soredia arising from pustules. The lobes of the thallus may be smooth, but quite often have a wrinkled appearance especially in older specimens. The lower surface is black except for a brown margin; rhizoids attached to the lower surface are black and unbranched.

Flavoparmelia caperata is a foliose lichen species characterized by its yellow-green to greenish-gray thallus, irregularly lobed with wavy margins, and presence of conical to cylindrical isidia. In East and Central Texas, it commonly grows on trees, particularly oak and cedar, as well as on rocks and fences, preferring full sun to partial shade and a wide range of substrates. The species is widely distributed in the region, found in various habitats including urban areas, woodland edges, and rocky outcrops, with a frequent occurrence in the Edwards Plateau and Post Oak Savannah ecoregions.
Common greenshield lichen (Flavoparmelia caperata)(?) on Caney Creek section of Lone Star Hiking Trail in Sam Houston National Forest near Huntsville. Texas, January 26, 2019

Common greenshield lichen (Flavoparmelia caperata)(?) in Big Creek Scenic Area of Sam Houston National Forest. Shepherd, Texas, February 1, 2019Lone Star Hiking Trail, Shepherd, TX 77371, USAObservations of Flavoparmelia caperata in East and Central Texas reveal its presence on tree species in the region. On January 26, 2019, the lichen was spotted on the Caney Creek section of Lone Star Hiking Trail in Sam Houston National Forest near Huntsville. A similar sighting occurred on February 1, 2019, in the Big Creek Scenic Area of Sam Houston National Forest, located in Shepherd, Texas. In both instances, Flavoparmelia caperata was found growing on trees, suggesting its ability to thrive in the forest environments of East and Central Texas. The lichen's presence in these areas indicates a tolerance for the regional climate and tree species, allowing it to establish itself in the wild. These observations contribute to a broader understanding of the species' distribution and habitat preferences in the region.
