Classification: Etheirophoraceae, Incertae sedis, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on wood in marine habitats. Sexual morph: Ascomata perithecial, solitary, immersed, pyriform, pale brown, coriaceous, papillate. Papilla conical, brown, ostiolate, periphysate, sometimes erumpent through the wood surface and surrounded by irregular, brown clypeus. Peridium composed of pale brown cells of textura angularis. Paraphyses filiform, septate, branched. Asci 8-spored, unitunicate, cylindrical to clavate, pedicellate, apex rounded or blunt, apical ring absent, evanescent. Ascospores bi-seriate, hyaline, ellipsoidal, straight or slightly curved, 1-septate, smooth-walled, with 5–8 filiform appendages at one or each end, guttulate. Asexual morph: Undetermined (adapted from Kohlmeyer & Volkmann-Kohlmeyer 1989).

Notes – Kohlmeyer & Volkmann-Kohlmeyer (1989) found Etheirophora bijubata (type), E. blepharospora and E. unijubata on rotten wood collected in Hawaii. They have ellipsoidal ascospores with several filiform terminal appendages at one or each end (Kohlmeyer & Volkmann-Kohlmeyer 1989). However, Schoch et al. (2007) sequenced E. blepharospora and E. unijubata. Subsequently, Jones et al. (2014) established Etheirophoraceae, which accommodated Etheirophora and Swampomyces. Etheirophora and Swampomyces that form a clade as Etheirophoraceae (Jones et al. 2014, this study, 100%ML/1.00BY). Swampomyces is different from Etheirophora in that its ellipsoidal ascospores lacks appendages (Jones et al. 2014).

Type species: Etheirophora bijubata Kohlm. & Volkm.-Kohlm., Mycol. Res. 92(4): 414 (1989).

Other accepted species: Species Fungorum – search Etheirophora.
