Ochrolechia trochophora is a crustose lichen that grows on trees, particularly oak and cedar, in warm and humid climates. In East and Central Texas, it is commonly found on the trunks and branches of live oaks and other deciduous trees, often in shaded or partially shaded areas. The thallus is yellow-green to grayish-green, with a rough, wart-like surface and numerous apothecia that are initially orange-red but fade to brown with age. It is a relatively small species, typically forming patches up to 5 cm in diameter.
