Saprobic on intertidal mangrove wood and roots, bark leaves, and sand in marine habitats. Sexual morph: Ascomata perithecial, hyaline, immersed or superficial, subglobose, ostiolate, papillate, subcarbonaceous to coriaceous. Paraphyses narrow, irregular, persistent or early deliquescing. Asci 8-spored, unitunicate, thin-walled, clavate to ellipsoidal, short pedicellate, lacking an apical ring, early deliquescing. Ascospores fasciculate, hyaline, cylindrical to ellipsoidal, 3–5-septate, with several radiating appendages at one or both ends. Asexual morph: Hyphomycetous. Hyphae septate, branched, hyaline. Conidiophores present or obsolete, cylindrical, clavate, septate or aseptate, acrogenous or laterally on the hyphae, hyaline to light brown. Conidia holoblastic, irregularly helicoid, muriform, cells of the conidia tightly fused, more or less similar in size and colour, acrogenous, solitary, constricted at the septa, yellow to brown. Conidial cells up to 50 in number (adapted from Maharachchikumbura et al. 2016b).

Type genusTorpedospora Meyers

Notes – Torpedosporaceae was introduced with two Torpedospora species and Glomerulispora mangrovis (asexual morph), based on molecular analysis of partial sequences of the nuclear SSU and LSU ribosomal DNA (Jones et al. 2014). Hence, the family comprised two genera, Torpedospora and Glomerulispora (Jones et al. 2014). However, G. mangrovei, grouped with the two Torpedospora species such that these generic names are considered synonyms (Abdel- Wahab et al. 2010, Jones et al. 2015). Based on the widespread utility of Torpedospora and its priority, the use of Torpedospora over Glomerulispora was recommended by Réblová et al. (2016b). The family groups in the Hypocreomycetidae, order incertae sedis (Jones et al. 2014, Maharachchikumbura et al. 2015b). Subsequently, Jones et al. (2015) had referred the family to a new order Torpedosporales and this was followed by Maharachchikumbura et al. (2016b) and Wijayawardene et al. (2018a).
