Pyrenidium is a genus of lichenicolous (lichen-dwelling) fungi. It is the only genus in the family Pyrenidiaceae. It has 13 species.
==Taxonomy== The genus was circumscribed by Finnish lichenologist William Nylander in 1865, with Pyrenidium actinellum assigned as the type species. The family was originally proposed by Alexander Zahlbruckner in 1898, and later resurrected for use in 2019. Pyrenidium was previously classified in Dacampiaceae, but molecular phylogenetic analysis showed that this family was polyphyletic, and that Pyrenidium originated from a lineage distinct from the genera in that family.
