Sulcopyrenula cruciata is a species of crustose lichen-forming fungus in the family Pyrenulaceae.[1] It was described from Brazil, where the type locality is in Serra do Caraça, Minas Gerais, at an elevation of 1,300 m (4,300 ft).[2] As of 2025, it had not been documented from any additional Brazilian states.[3]

The lichen grows on exposed soft bark and, in the type collection, was found without accompanying species. It has a whitish, crust-like thallus that is almost immersed in the bark and lacks both pseudocyphellae and a hypothallus. Its black perithecia are mostly immersed in the thallus, and its ascospores are brown, grooved, and consistently divided into four spindle-shaped (fusiform) chambers arranged in two rows. The species also contains lichexanthone, detected by its yellow ultraviolet fluorescence. Within Sulcopyrenula, it is distinctive in combining lichexanthone with consistently four-loculate ascospores; it resembles Anthracothecium subglobosum in sharing those general features, but differs in having narrower, grooved spores and a clear rather than inspersed (i.e., containing oil-droplets) hamathecium.[2]
