Sclerococcum is a genus of lichenicolous fungi in the family Dactylosporaceae.

Most of the Sclerococcum species described since then are also lichenicolous, and most have a restricted host range.

Molecular phylogenetics analysis published in 2012 showed that Sclerococcum sphaerale grouped together in a clade with species of Dactylospora in the class Eurotiomycetes.

[2] In 2016, Réblová and colleagues proposed a new family Sclerococcaceae in a new order (Sclerococcales) to accommodate the type genus Sclerococcum, Dactylospora, Rhopalophora, three strains of beetle-associated fungi, and an isolate of Fusichalara minuta.

[3] This classification was not accepted in the 2017 Outline of the Ascomycota, which retained the family Dactylosporaceae.
