Type species – Semifissispora fusiformis Swart, Trans. Br. mycol. Soc. 78(2): 259 (1982).
Notes – Semifissispora was introduced for some fungi associated with leaf litter of Eucalyptus spp. (Swart 1982). Semifissispora is related to Massarinaceae (Crous et al. 2015d). Semifissispora natalis was found associated with the dried part of infected Eucalyptus leaves. However, tests are needed to confirm its pathogenicity (Crous et al. 2015d). Semifissispora has fusiform, hyaline, 1-septate ascospores, prominently constricted at septum and bending at maturity (Swart 1982, Crous et al. 2015d). Asexual morph produced in culture has solitary conidiomata with sub-cylindrical, aseptate and hyaline conidia (Crous et al. 2017a).
