Sarrameanaceae is a family of lichen-forming fungi in the monotypic order Sarrameanales. The family was established in 1984 by Josef Hafellner and contains three genera. These lichens form crust-like growths that often produce powdery reproductive structures for spreading to new locations. They have brown to black fruiting bodies and show remarkable diversity in ascospore shapes, with some species coiling their spores in tight spirals within their reproductive structures.
