Pyxine sorediata is a foliose lichen characterized by its yellowish to greenish-gray thallus with rounded lobes and numerous soralia containing white or pale yellow soredia. In East and Central Texas, it typically grows on trees, particularly oak and cedar, in shaded to partially shaded areas. It is often found in humid environments, such as near streams or lakes, and can tolerate a range of substrates, including bark and rock. The species is relatively common in the region, with sightings reported in counties including Travis, Bastrop, and Houston.
