从沙特阿拉伯Al-Leith市红海沿岸3个红树林遗址采集的833份Avicennia marina潮间带腐木样本中记录到12种真菌（10种子囊菌，1种无性真菌和1种担子菌）。常见的真菌有：Nia sp.（10%）、Sammeyersia grandispora（8.5%）、Fulvocentrum rubrum sp.（5.8%）、Marinosphaera mangrovei（4.2%）和Okeanomyces cucullatus（4.2%）。在记录的真菌中，有6个分类群可能是科学上的新发现，本文根据形态和LSU rDNA序列分析对其中的Fulvocentrum rubrum sp. nov.进行了描述。系统发育分析将该新种定位于鱼雷科。黄斑虫的特征是长至浅表的膜状ascoma，颈部长而宽；子囊孢子具有顶环和3-5隔的子囊孢子，比先前描述的两个Fulvocentrum种的子囊孢子大。红毛镰刀菌与埃及镰刀菌和棍孢镰刀菌的不同之处在于，它的子囊孢子长而宽，子囊孢子周围有胶状鞘和顶环。
Twelve fungi (ten ascomycetes, one asexual fungus, and one basidiomycete) were recorded from 833 samples of intertidal decayed wood of Avicennia marina collected from three mangrove sites at the Red Sea coast of Al-Leith city, Saudi Arabia. Common fungi were: Nia sp. (10%), Sammeyersia grandispora (8.5%), Fulvocentrum rubrum sp. nov. (5.8%), Marinosphaera mangrovei (4.2%) and Okeanomyces cucullatus (4.2%). Among the recorded fungi, six taxa are potentially new to science, of which Fulvocentrum rubrum sp. nov. is described in this article based on morphology and LSU rDNA sequence analysis. Phylogenetic analyses positioned the new species within the family Juncigenaceae, Torpedosporales. Fulvocentrum ruhrum is characterized by erumpent to superficial, membraneous ascomata with long and wide necks; asci with apical ring and 3-5-septate ascospores that are larger than those recorded in the two previously described Fulvocentrum species. Fulvocentrum rubrum differs from F. aegyptiacum and F. clavatisporum by having longer and wider ascospores that are surrounded by a gelatinous sheath and an apical ring in the ascus.
