Traustochytrid is a kind of Protista distributing widely in the littorals, estuaries, saline lakes and mangrove areas. They belong to Chrostima. Thalli are monocentric and are similar to the genus Chytridium. They have diflagellate zoospores or non-flagellate aplanospores. Thalli include sporangia and ectoplamic nets. Most traustochytrids are saprophytic on the debris of high vascular bundle plants and algae, and some are parasitic on invertebrate. No thraustochytrids have been documented about their sexual reproduction in life cycle. Traustochytrids in this experiment are isolated from the water sample collected in Danshui mangrove in Jhuwei, Taipei and baited by the Virginia pine pollen. They are isolated and purified by streaking on the KMV media containing antibiotics. When getting the pure isolate, they are transferred to the KMV media without antibiotics or to the incubated seawater and pine pollen media. The observation and description are made according to their morphological characteristics in the KMV media or in the seawater and pine pollen media. In this experiment, three genus and fourteen species are examined sucessessfully： eight species of Traustochytrium： T. motivum Goldstein, T. aureum Goldstein, T. rossi Bahnweg and Sparrow, T. kinnei Gaertner, T. antarticum Bahnweg and Sparrow, T. pachydermum Scholz, T. aggregatum Ulken and T. sp.； two species of Schizochytrium： S. aggregatum Goldstein and Belsky and S. limacinum Honda and Yokochi； four species of Ulkenia： U. visurgensis （Ulken） Gaertner, U. sarkariana Gaertner, U. radiate Gaertner and U. sp.. There are two new recorded species in Taiwan, including S. limacinum and U. sarkariana. The auther also discovered two new species, which belong to the genera Traustochytrium and Ulkenia.
