Type species – Dictyosporella aquatica Abdel-Aziz
Notes – Dictyosporella was introduced by Ariyawansa et al. (2015) to accommodate an asexual morph species, D. aquatica, which is characterized by micronematous conidiophores and brown to black, muriform conidia. Based on phylogenetic analyses of LSU sequence data, Dictyosporella was assigned to Annulatascaceae (Ariyawansa et al. 2015). Zhang et al. (2017a) introduced a sexual morph species, D. thailandensis, and treated Dictyosporella as Diaporthomycetidae, genera incertae sedis. Luo et al. (2019) transferred Dictyosporella to Junewangiaceae based on multi-gene phylogenetic analyses.
