Notes – Neodidymella was introduced by Ariyawansa et al. (2015a) as a sexual genus under Didymellaceae. Neodidymella forms a sister clade to Remotididymella, which was introduced as an asexual genus by Valenzuela-Lopez et al. (2018). However, Jayasiri et al. (2019) provided the sexual morph of Remotididymella. Morphologically these two genera can be differentiated based on asci. Neodidymella species develop asci which are ellipsoidal to clavate, 1-septate, slightly constricted at the septum (Ariyawansa et al. 2015a), whereas Remotididymella develop asci which are fusiform, 1–3-septate, constricted at middle septum, containing up to four refractive oil globules and are irregular (Jayasiri et al. 2019).
