Sexual morph: saprobic, ascomata 240-280 µm high, 170-190 µm in diameter, pyriform, immersed, oblique or vertical to the host surface, dark brown to black, coriaceous, ostiolate, contents apricot coloured in mass, single, developing under a thin darkened superficial pseudo stroma, covering the area where ascomata develop and composed of host cells with darkened fungal hyphae. Neck 70-80 µm in diameter, filled with periphyses. Peridium 8-10 µm thick, comprising brown to dark brown polygonal cells. Paraphyses numerous, hyaline, in a gel, mostly unbranched, attached to the apex of the ascomatal cavity. Asci 145-155 × 9-10 µm, 8-spored, cylindrical, thin-walled, short pedicellate and apically thickened. Ascospores 15-20 × 6-8 µm, 3-septate, ellipsoidal, hyaline, uniseriate, constricted at the septa and smooth. Asexual morph: Undetermined (Description based on Abdel-Wahab et al. (2001)).

NOTES: This species is very common on intertidal wood of Avicennia marina in Red Sea mangroves both on the Egyptian coast (Abdel-Wahab 2005) and from Arabian Gulf mangroves of the Saudi Arabia coast (Abdel-Wahab et al. 2014). Phylogenetic analyses based on ribosomal genes placed Fulvocentrum species in a monophyletic clade with the genera Juncigena and Marinokulati under Juncigenaceae (Jones et al. 2014). The genus is accepted as a member of the Juncigenaceae (Torpedosporales) by Jones et al. (2015) and Maharachchikumbura et al. (2015).
