Synonym: Trypethelium carolinianum.
Bathelium carolinianum is a crustose lichen that grows on bark and wood. It has a gray to brownish-gray thallus with a rough, wart-like surface. In East and Central Texas, it is commonly found on deciduous trees, particularly oak and hickory, in shaded areas with high humidity. The lichen produces dark brown to black perithecia that are partially immersed in the thallus. It is a relatively rare species in the region, but can be locally abundant in areas with suitable habitat.
