Dimelaena oreina is a crustose lichen that grows on rocky substrates. In East and Central Texas, it is commonly found on limestone and sandstone outcrops, forming yellow to orange-yellow patches with a rough, wart-like texture. The thallus is typically 1-5 cm in diameter, with numerous apothecia containing yellow to brown spores. It thrives in full sun to partial shade and is often associated with other lichens and mosses in areas with low to moderate vegetation cover.
