在一项对沙特阿拉伯海洋真菌的研究中，在沙特阿拉伯达曼市El霍巴尔海滨潮间带采集的浮木上记录了一种未描述的分类群。本文描述了一个新分类群--卡累吉酵母属（Khaleijomyces），为一新属和一新种，即卡累吉酵母K.马里纳成立。SSU和LSU rDNA数据集相结合的系统发育分析定位灯心草科，Torpedosporales内的新属。其他系统发育相关的属是：Fulvocentrum，Juncigena和Marinokulati。Khaleijomyces的形态与上述三属不同，其特征是：杏黄色至红褐色，膜质，表面至浸入的子囊，长颈，具周囊;淡褐色的子囊腹，是鱼雷孢目成员的共同特征;透明，多滴和单细胞的子囊孢子，幼时变为浅棕色至棕色，老的标本有1-4个隔。
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.
