Crittendenia is a genus of lichenicolous (lichen-dwelling) fungi in the monogeneric family Crittendeniaceae. The genus was circumscribed in 2021 to contain two species, C. lichenicola, and the type, C. coppinsii; these species were previously classified in the genus Chionosphaera. An additional 16 species were added to the genus the following year.[1] The genus name honours British lichenologist Peter Crittenden.[2]
Characteristics of Crittendenia include the tiny synnemata-like basidiomata, clamp connections, and aseptate tubular basidia from which 4–7 spores discharge passively, often in groups.[2] The genus was originally considered to be of uncertain classification in the Agaricostilbomycetes;[3] the family Crittendeniaceae was proposed in 2022 to contain the genus following molecular phylogenetic investigation.[1]
