During an ongoing study of marine fungi from Saudi Arabia, an undescribed taxon was recorded on driftwood collected from intertidal zone at El Khobar sea front, Dammam city, Saudi Arabia. A new taxon, Khaleijomyces, is described in here as a new genus and a new species, K. marinus is established. Phylogenetic analyses of a combined SSU and LSU rDNA dataset position the new genus within the family Juncigenaceae, Torpedosporales. Other phylogenetic related genera are: Fulvocentrum, Juncigena and Marinokulati. The morphology of Khaleijomyces is different from the above three genera and it is characterized by apricot to reddish-brown, membranous, superficial to immersed ascomata with long, periphysate necks; faint apricot-color ascomatal venter, a common character in members of Torpedosporales; hamathecium consists of pseudoparenchymatous tissue that breaks down into catenophyses; cymbiform to fusiform, thin-walled asci, without apical apparatus; hyaline, multi-guttulate and unicellular ascospores when young becoming light-brown to brown in color and 1–4 septate in old specimens.
