Notes – The monotypic genus Corynesporasca was introduced by Sivanesan (1996) to accommodate Co. caryotae. It is characterized by cleistothecioid ascomata, bitunicate and 8-spored asci and oblong, 3-septate ascospores mostly with a supramedian primary septum (Sivanesan 1996). Sivanesan (1996) linked Corynesporasca with an unnamed Corynespora asexual morph based on culture studies. However, Hyde et al. (2013) did not synonymize Corynesporasca under Corynespora, as Corynespora was shown to be polyphyletic (Tanaka et al. 2005c, 2015, Schoch et al. 2009a, Voglmayr & Jaklitsch 2017). The type species of Corynespora and Corynesporasca (Corynespora cassiicola and Corynesporasca caryotae) may be unrelated (Hyde et al. 2013). Moreover, Corynespora-like asexual morphs have been shown in many genera (Seifert et al. 2011). Although Corynesporasca was treated as a synonym of Corynespora in several studies (Rossman et al. 2015, Wijayawardene et al. 2017a, 2018), we choose to follow Hyde et al. (2013) and suggest Corynespora and Corynesporasca are distinct genera until molecular data of the type species are available. The phylogenetic relationships of these two genera need to be further revealed.
