MycoBank number: MB 808177; Index Fungorum number: IF 808177; Facesoffungi number: FoF 01665; 8 species.
Saprobic intertidal wood, mangrove and herbaceous wood and roots, bark, leaves in marine habitats. Sexual morph: Ascomata perithecial, globose, subglobose, ovoid to pyriform, immersed, erumpent to superficial, subcoriaceous to coriaceous, olivaceous-brown, brown to dark–brown to black, hyaline to yellow-orange to reddish-brown, ostiolate, periphysate, papillate or hyaline to apricot coloured long neck surrounded by dense brown, septate hyphae. Peridium comprising several cell layers of ellipsoidal to subglobose cells forming textura angularis, textura epidermoidea or both, or textura prismatica or textura globulosa. Paraphyses numerous, narrow, branched or unbranched, persistent, connected to the apex and base of the peridium or catenophyses. Asci 8–spored, unitunicate, thin–walled, persistent, clavate, cymbiform, cylindrical to fusiform, short pedicellate, with or without apical ring. Ascospores 1-3 seriate, hyaline, ellipsoidal, clavate to fusiform, unicellular, or 1–4–septate, with or without equatorial and polar or subpolar appendages. Asexual morph: hyphomycetous. Hyphae septate, branched, hyaline to brown. Conidiogenous cells non–specialized, short, lateral, solitary, helicoid, septate, and light to dark brown. Conidia brown, single, helicoid, septate, constricted at the septa (adapted from Abdel- Wahab et al. 2010, Jones et al. 2014, Maharachchikumbura et al. 2015, Poli et al. 2019).
Type genus – Juncigena Kohlm., Volkm.-Kohlm. & O.E. Erikss.
Notes – Juncigenaceae was typified by Juncigena by Jones et al. (2014) and included the genera Fulvocentrum, Marinokulati and Moheitospora. They formed a phylogenetically stable monophyletic clade in a SSU and LSU based phylogeny. Juncigenaceae is sister to Etheirophoraceae, Falcocladiaceae and Torpedosporaceae in the subclass Hypocreomycetidae. Jones et al. (2014) introduced Fulvocentrum to accommodate F. aegyptiacum and F. clavatisporium, which were previously introduced under Swampomyces sensu stricto. Likewise, the marine ascomycete Chaetosphaeria chaetosa did not group in Chaetosphaeria sensu stricto (Chaetosphaeriales) and was transferred to a new genus Marinokulati (Jones et al. 2014). In Jones et al. (2014), Juncigenaceae was placed in the subclass Hypocreomycetidae, order incertae sedis. This was supported by Maharachchikumbura et al. (2015). Jones et al. (2015) placed Etheirophoraceae, Juncigenaceae and Torpedosporaceae in Torpedosporales. Abdel-Wahab et al. (2018) introduced Khaleijomyces as sister to Juncigena and Poli et al. (2019) introduced Elbamycella as a separate lineage in Juncigenaceae.
