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

Based on phylogenies of SSU and LSU rDNA sequences using maximum parsimony and maximum likelihood analyses, Fulvocentrum (Juncigenaceae, Torpedosporales) was proposed to accommodate Swampomyces aegyptiacus and S. clavatispora by Jones et al. (2014), and named F. aegyptiaca (type species) and F. clavatisporium, respectively. Fulvocentrum aegyptiaca and F. clavatisporium have been introduced as marine fungi from the Red Sea mangroves in Egypt (Abdel-Wahab et al. 2001). Abdel-Wahab et al. (2019) introduced another marine fungus, F. rubrum, collected from the Red Sea mangroves in Saudi Arabia. Currently, this genus comprises only three species of the Index Fungorum (2024). Fulvocentrum is characterized by pyriform, immersed or superficial ascomata, dark brown to black, coriaceous, ostiolate, apricot content in mass, neck filled with periphyses, thin peridium, brown to dark brown, consisting of polygonal cells or textura angularis cells, hyaline and unbranched paraphyses attached to the top and bottom of the ascomatal cavity, cylindrical or fusiform to obclavate asci, short pedicellate and apically thickened with ellipsoidal or clavate ascospores, septate, hyaline, uniseriate, constricted at the septa, and smooth (Jones et al. 2014, Abdel-Wahab et al. 2019).
