During the germination experiments of the cysts of the toxic dinoflagellate Alexandrium tamarense, we found that the germinated cells were infected by a kind of parasitic fungus. Purpose of this study was to identify the fungus by examining the morphology and the development with light and electron microscopes. Ultrastructure of the zoospore and rDNA sequences indicate that the fungus belong to Chytridiales. Our finding is the first report of fungal parasitism on the toxic marine dinoflagellate and suggests that chytrid fungus may play an important role in marine environment as in freshwater system.

在毒性鞭毛藻亚历山大tamarense的囊肿的发芽实验中，我们发现发芽的细胞被一种寄生虫感染。这项研究的目的是通过使用光和电子显微镜检查形态和发育来鉴定真菌。 zoo孢子和rDNA序列的超微结构表明真菌属于chytridiales。我们的发现是对有毒海洋鞭毛藻的真菌寄生虫的第一个报告，并表明Chytrid真菌可能在海洋环境中像淡水系统一样在海洋环境中起重要作用。
