Type genusEtheirophora Kohlm. & Volkm.-Kohlm.

Notes – This family includes the genera Etheirophora (E. bijubata, E. blepharospora, E. unijubata) and Swampomyces (S. armeniacus, S. triseptatus) (Jones et al. 2014). However, the genera Etheirophora and Swampomyces are not congeneric and they form a sister clade with Falcocladium species (Falcocladiaceae) in an unsupported clade in Hypocreomycetidae, order incertae sedis (Maharachchikumbura et al. (2015). Subsequently, Jones et al. (2015) introduced Torpedosporales to accommodate the families Etheirophoraceae, Juncigenaceae and Torpedosporaceae. The order evolved with a stem age of 171–241 MYA (Hongsanan et al. 2017, Hyde et al. 2017a).
