Sclerococcum

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

Taxonomy
The genus was circumscribed in 1825 by Elias Magnus Fries. The type species is Sclerococcum sphaerale, originally described in 1814 by Erik Acharius (as Spiloma sphaerale). This fungus is a lichenicolous hyphomycete – a mould that lives on a lichen. 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.

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