Based on multiple-gene analyses of LSU, tef1 and rpb2 sequence data by Hansen et al. (2013), Boubovia Svrček and Coprotus Korf & Kimbr. formed a sister lineage to Ascodesmidaceae J. Schröt. Despite previous results, Jaklitsch et al. (2016) and Ekanayaka et al. (2018) suggested integrating them into Ascodesmidaceae. Following subsequent analyses by Lindemann et al. (2019), Van Vooren (2021) erected Coprotaceae to accommodate them. Coprotaceae species are usually found on dung of herbivores and omnivorous animals, rarely on soil, duff and rotten leaves (Kušan et al. 2018). They are found in eastern and southwestern Asia, Europe, and the USA (Kušan et al. 2018). There are 35 species in Coprotaceae, including 28 Boubovia species and seven Coprotus species (Index Fungorum 2023). Van Vooren (2021) established Coprotaceae, with Coprotus as the type genus and Coprotus sexdecimsporus as the type species. Coprotaceae is characterized by glabrous and sessile apothecia, mostly bent to uncinate paraphyses with numerous refractive bodies when live, operculate, 8–256-spored, inamyloid asci, and uni- or irregularly biseriate, ellipsoid ascospores with De Bary bubbles when dry. The phylogenetic evidence of multiple-loci analyses show it as an independent lineage sister to Ascodesmidaceae (Lindemann et al. 2019, Van Vooren 2021). The taxonomic placement of Coprotaceae is in Pezizales (Pezizomycetes).
