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

Saprobic on wood in marine habitats. Sexual morph: Ascomata perithecial, solitary, immersed, pyriform, pale brown, with black papilla on surface view, coriaceous, ostiolate, periphysate. Peridium composed of pale brown to hyaline cells of textura epidermoidea to textura angularis to textura prismatica. Pseudoparaphyses filiform, septate, branched, attached at the top and bottom. Asci 8-spored, unitunicate, cylindrical, pedicellate, apex rounded or blunt, apical ring absent, evanescent. Ascospores uni-seriate, hyaline, ellipsoidal, hyaline to yellowish, septate, verrucose, guttulate. Asexual morph: Undetermined (adapted from Kohlmeyer & Volkmann-Kohlmeyer 1987).

Notes – Swamponyces was established for S. armeniacus which was collected on mangrove wood in Belize (Kohlmeyer & Volkmann-Kohlmeyer 1987). Subsequently, S. aegyptiacus, S. clavatisporus and S. triseptatus were introduced from mangrove substrates with immersed ascomata and ellipsoidal, septate ascospores (Hyde & Nakagiri 1992, Abdel-Wahab et al. 2001). These species were sequenced by Sakayaroj et al. (2005) and Schoch et al. (2007). Thus, phylogenetically, Swampomyces aegyptiacus and S. clavatisporus were clarified as Fulvocentrum species in Juncigenaceae; while, Etheirophora and Swampomyces clustered in Etheirophoraceae (Jones et al. 2014, this study).

Type species: Swampomyces armeniacus Kohlm. & Volkm.-Kohlm., Bot. Mar. 30(3): 200 (1987).

Other accepted species: Species Fungorum – search Swampomyces.
