Juncigenaceae was introduced by Jones et al. (2014) to accommodate Juncigena as the type genus and to include the genera Fulvocentrum, Marinokulati and Moheitospora. Juncigenaceae members mainly have been found on driftwood collected from the intertidal zone, submerged sea grasses and brown alga (Abdel-Wahab et al. 2010, Poli et al. 2019). Mostly species have perithecial, globose, subglobose, ovoid to pyriform, subcoriaceous to coriaceous ascomata, unitunicate, clavate, cymbiform, cylindrical to fusiform, short pedicellate asci with or without apical ring and 1-3 seriate, hyaline, ellipsoidal, clavate to fusiform, unicellular, or 1–4-septate ascospores. Asexual morph is hyphomycetous and has brown, single, helicoid, septate conidia (Jones et al. 2014, Maharachchikumbura et al. 2015, Poli et al. 2019). Currently, six genera are accepted in Juncigenaceae, viz. Elbamycella, Fulvocentrum, Juncigena, Khaleijomyces, Marinokulati and Moheitospora (Wijayawardene et al. 2020). The nuclear SSU and LSU rDNA molecular markers were used to elucidate the phylogenetic position of this family (Jones et al. 2014).

Type genus: Juncigena Kohlm., Volkm.-Kohlm. & O.E. Erikss.

Other accepted species: Species Fungorum – search Juncigenaceae
