Acarosporales

The Acarosporales are an order of fungi in the class Lecanoromycetes. Phylogenetic analyses conducted using the sequences of both the protein-coding gene RPB2 as well as nuclear ribosomal genes place this order within the subclass Acarosporomycetidae.

The Acarosporaceae are a family of fungi in the order Acarosporales. Members of this family have a widespread distribution, and are mostly lichenized with green algae. According to a 2021 estimate, the family contains 11 genera and about 260 species. The family is characterised by a formed of paraphysoids (hyphal structures similar in function to true paraphyses, but often branched and forming a network).

Sarcogyne is a genus of crustose lichen-forming fungi in the family Acarosporaceae. It was circumscribed by German botanist Julius von Flotow in 1850. A proposal has been put forth in 2021 to assign Sarcogyne clavus as the type species of the genus, "as it represents the original concept of Sarcogyne as having melanized apothecia without algae in the margin".

Polysporina is a genus of fungi in the family Acarosporaceae. The genus was circumscribed by the Czech lichenologist Antonín Vězda in 1978. Some of the species form lichens, while others are species of lichenicolous (lichen-dwelling) fungi.

Pleopsidium is a genus of lichen-forming fungi in the family Acarosporaceae (order Acarosporales). The widespread genus was circumscribed by lichenologist Gustav Wilhelm Körber in 1855. After a 2025 revision of the genus, it comprises eight species.
