Myriostigma is a genus of lichens in the family Arthoniaceae.[1] The genus was circumscribed by German lichenologist August von Krempelhuber in 1874.[2]

Characteristics of Myriostigma include the raised maculate (spots), ascomata-like fertile areas, asci that are 8-spored, thick-walled, globular and stalked, and ascospores that are hyaline, bean-shaped, and muriform (divided into chambers by septa).[3]
