            Hypocreomycetidae, Torpedosporales, Etheirophoraceae, Swampomyces

Index Fungorum number: IF6004; Facesoffungi number: FoF 08401; 2 morphological species; 2 species with sequence data.


Saprobic on intertidal wood and bark in marine habitats. Sexual morph: Ascomata subglobose to globose or pyriform, immersed, light brown to dark brown or black, oblique or vertical to the host surface, clypeate, coriaceous, ostiolate. Ostiole papillate, periphysate. Peridium comprising several layers of brown to dark brown cells of textura angularis. Paraphyses abundant, septate, mostly unbranched, attached to the apex of the ascomatal cavity, embedded in a gelatinous matrix. Asci 8-spored, unitunicate, cylindrical to oblong, pedicellate, persistent, with J- refractive apical apparatus. Ascospores 1–2-seriate, hyaline, ellipsoidal, 1- to many septate, constricted at the septa, appendage normally absent. Appendages bristle-like, origin undetermined. Asexual morph: Undetermined (adapted from Jones et al. 2014).


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


Notes: When it was first described, the genus Swampomyces was tentatively assigned to Phyllachorales based on their similar morphological characters, including presence of a clypeus, paraphyses and ascal apical apparatus (Kohlmeyer and Volkmann-Kohlmeyer 1987). However, the mode of life of Phyllachorales and Swampomyces differed significantly, such that while species of Phyllachorales are biotrophic on stems and leaves of herbaceous plants, members of Swampomyces are saprobic on woods in marine habitats. Later phylogenetic analysis showed that Swampomyces did not cluster within Phyllachorales (Sakayaroj et al. 2005). A new family, Etheirophoraceae was consequently introduced to accommodate the genus along with Etheirophora (Jones et al. 2014). Abdel-Wahab et al. (2001) added S. triseptatus (Hyde & Nakagiri 1992), S. clavatispora and S. aegyptiacus to Swampomyces. Subsequently, S. aegyptiacus and S. clavatispora were transferred to Fulvocentrum by Jones et al. (2014).
