Ciposia

Ciposia is a single-species fungal genus in the family Caliciaceae. Circumscribed by Bernhard Marbach in 2000, it contains the species Ciposia wheeleri, a corticolous and crustose lichen. This species was originally classified in genus Buellia by Richard C. Harris in 1988.
According to Index Fungorum, Ciposia is not a correct name, as its publication was predated by a homonym, the plant genus Ciposia, which was published by Brazilian botanist Alvaro Astolpho da Silveira in 1918. The earliest-published name has precedence according to the Principle of priority.
