Allographa lichexanthonica is a species of crustose lichen-forming fungus in the family Graphidaceae. It is a white, bark-dwelling lichen with wavy, prominently raised, slit-like fruiting bodies, known only from lowland forest in the Colombian Amazon. The species was described in 2023 and is named for its content of lichexanthone, which causes the thallus to fluoresce yellow under ultraviolet light.
