Type species – Torpedospora radiata Meyers
Notes – Torpedospora is characterised by torpedo-like, cylindrical to elongate-ellipsoidal ascospores, together with the radiating appendages at one or both ends. This genus comprises three species, T. ambispinosa, T. mangrovei, and T. radiata (type). Molecular studies by Sakayaroj et al. (2005), Schoch et al. (2007), Abdel Wahab et al. (2010) and Jones et al. (2015) showed that they group in the same clade with high bootstrap support, which suggest that they are congeneric. A study by Abdel-Wahab et al. (2018) also supported this.
