Classification: Morosphaeriaceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi

Morosphaeria was introduced by Suetrong et al. (2009) for two Massarina species M. ramunculicola and M. velatispora. Subsequently, Boonmee et al. (2012) transferred Kirschsteiniothelia elaterascus to Morosphaeria based on phylogenetic analysis. However, this species was transferred to Helicascus by Zhang et al. (2013a). Devadatha et al. (2018a) introduced a new species M. muthupetensis. Therefore, three species are accepted in this genus based on morphology and phylogenetic analysis and all are reported from marine habitats (Devadatha et al. 2018a).

Type species: Morosphaeria velatispora (K.D. Hyde & Borse) Suetrong, Sakay., E.B.G. Jones & C.L. Schoch, Stud. Mycol. 64: 161 (2009).

Other accepted species: Species Fungorum – search Morosphaeria.
