The Papulosaceae are a family of fungi in the class Sordariomycetes and in the subclass Diaporthomycetidae.
[1] The family has not been assigned to any order (incertae sedis).
[2] A monotypic taxon, the Papulosaceae contained the single genus Papulosa, which in turn contains the single species Papulosa amerospora.
[3] This species, found in the eastern USA, grows in Juncus stems.
[4] In 2020, 3 other fungal genera joined the taxon of Papulosa.
