Notes: Torpedospora was established by Meyers (1957), and typified by T. radiata. Currently, Torpedospora comprises three species: T. ambispinosa, T. mangrovei and T. radiata, which were reported from marine habitats in America and Japan (Meyers 1957; Jones 1985; Abdel -Wahab et al. 2010; Jones et al. 2015; Réblová et al. 2016). Among them, T. mangrovei (formerly synonymized as Glomerulispora mangrovei) was accepted based on phylogenetic analyses of the combined LSU and SSU sequence data (Abdel-Wahab et al. 2010; Jones et al. 2015; Réblová et al. 2016). The asexual morph of Torpedospora is characterized by cylindrical, clavate, septate or aseptate, hyaline to pale brown, conidiophores, holoblastic conidiogenous cells, and solitary, irregularly helicoid, acrogenous, muriform conidia comprising up to 50 conidial cells (Abdel-Wahab et al. 2010). Conidiophores are sometimes absent (Abdel-Wahab et al. 2010). Its sexual morph has cylindrical to clavate, or elongated to ellipsoidal ascospores with subterminal, radiating appendage spores (Meyers 1957; Jones 1985).

Type species: Torpedospora radiata Meyers, Mycologia 49: 496 (1957).
