Dangeardiella was introduced by Saccardo and Sydow (1899), with Dangeardiella macrospora as the type species. The phylogenetic status of Dangeardiella is uncertain and has been placed in Dothideales genera incertae sedis (Hawksworth et al. 1995), or Melanommataceae in Pleosporales (Kirk et al. 2008) or Dothideomycetes genera incertae sedis (Lumbsch and Huhndorf  2010) and was located in Pleosporales genera incertae sedis in the latest treatments (Thambugala et al. 2014; Hongsanan et al. 2020a; Hyde et al. 2024c, Pem et al. 2024). Dangeardiella comprises two species, D. fusiformis and D. macrospora, which are saprobic on stalks and petioles of ferns. Members of the genus are known for their sexual morph characterized by black ascomata with an indistinct slit-like ostiole, aseptate pseudoparaphyses, bitunicate asci with short pedicels and 5–10 septate, fusoid to fusiform, hyaline ascospores (Saccardo and Sydow 1899; Holm and Holm 1978; Thambugala et al. 2014). This genus only has SSU sequence of D. macrospora available.

Type species: Dangeardiella macrospora (J. Schröt.) Sacc. & P. Syd.
