Lecanora sanctae-helenae is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecanoraceae. It was formally described as a new species in 1893 by Swiss botanist Johannes Müller Argoviensis, from specimens collected in Saint Helena Island by British amateur naturalist John Charles Melliss. The type locality is referenced in the species epithet.[1] More than a century later, it was accepted in a 1995 revision of the species complex related to Lecanora subcarnea.[2] For decades it was thought to be endemic to this island, where it occurs on siliceous rocks. It was reported from Ascension Island in 2008, where it is locally common.[3]
