Description Although here included in the genus Prymnesium this species differs markedly form other species of Prymnesium, in the list. Cells are ovoid-pear shaped (6–12 μm long and 5–9 μm wide). The two flagella are 2-3 times cell length and the stiff, uncoiling haptonema is 1-1½ cell length when fully extended. Cells are covered with four types of organic scales, which are species characteristic. For critical identification to species level, the scales need to be examined, using transmission electron microscopy. In preserved samples, scales scales may have been shed, in which case molecular sequencing is required for identification. [details]

Distribution The known distribution is rather patchy: Britain, Northern Europe, the Black Sea, Tasmania and the Southern Ocean. [details]
Editor's comment This species, usually known as Chrysochromulina polylepis, has recently been transferred to Prymnesium, based on some molecular data [details]
Harmful effect Serious fishkills took place in Scandinavia in 1988, but the toxic principle has not been determined [details]
Identification P. polylepis, also known as Chrysochromulina polylepis, is characterized by a rather short haptonema, which reaches 1-1.5 times cell length and is capable of coiling. The cell is covered with four types of organic scales, all of which are characteristic of this species. They are visible in the electron microscope only.. Cells with a slightly different complement of scales are sometimes observed,. which are part of the life cycle. Such cells have three types of scales only, one of them with a spiine, while spined scales are absent in the main cell type. [details]
