本文描述了采自日本横滨八景岛海滩浮木的一种新的盐珊瑚属植物，并与该属的其它种进行了比较。新的真菌和它的无性型一起生长在一块腐烂的木头上。SSU和LSU rDNA序列的两种变体是99%相似。对这两种变种的SSU和LSU rDNA序列的系统发育分析证实了它们之间的无性型-有性型关系，并将新真菌归入Halosarpheiasensu stricto分支。Halosarpheia japonicis的特征是其极性附属物最初被包裹在细胞鞘中，溶于水，然后膨胀形成巨大的树状结构。其他三个物种目前包括在Halosarpheiasensu stricto不同于H.japonicaby，有两个极性附属物，在水中展开形成长长的细丝。
A newHalosarpheiaspecies, collected from driftwood from Hakkeijima beach, Yokohama, Japan, is described and illustrated and is compared with other species of the genus. The new fungus was growing together with its anamorph on a piece of decaying wood. SSU and LSU rDNA sequences for both morphs were 99% similar. Phylogenetic analyses of SSU and LSU rDNA sequences of the both morphs confirm their anamorph–teleomorph relationship and placed the new fungus in theHalosarpheiasensu stricto clade with high statistical support.Halosarpheia japonicais characterized by its polar appendage that is initially enclosed in a cellular sheath and dissolves in water, the appendage then swells to form a huge tree-like structure. The other three species currently included inHalosarpheiasensu stricto differ fromH.japonicaby having two polar appendages that uncoil in water to form long filaments.
