Pleopsidium oxytonum is a crustose lichen that grows on calcareous rocks and soil. In East and Central Texas, it typically forms yellowish-green to grayish patches with a smooth, cracked, or blistered surface. The thallus is usually 0.1-0.5 mm thick, and apothecia are rare. It prefers full sun to partial shade and can be found on limestone outcrops, rocky hillsides, and caliche soils.
