Identification This species, belonging to the Alexandrium tamarense species complex, can only be unambiguously identified using genetic techniques. This species was identified as Gonyaulax catenella or Alexandrium catenella in temperate waters of western Pacific Ocean and Mediterranean Sea. Genetically, it was named as Temperate Asian (TA) clade and Group IV. [details]

Description Cells are as wide as long or slightly wider than high. In exponentially growing culture, cells of ACPP01 are 34.3 ± 2.92 μm (min 30 μm, max 38 μm, n = 20)wide and 35.7 ± 3.39 μm (min 30 μm, max 40 μm,n = 20) long, with a L:W ratio of 1.04. Cell contains many golden brown elongated chloroplasts and a horseshoe-shaped nucleus located in the equatorial part of the cell. The epicone is helmet-shaped, often presenting more or less noticeable shoulders, and the hypocone is roughly trapezoidal. The cingulum is descending about one cingular height.The sulcus broadens in its antapical portion andis delimited on both sides by moderately developed sulcal lists. The cell surface is smooth andornamented with many scattered small pores. The plate formula is: Po, 4', 6'', 5C, 8-10S, 5''', 2''''. Po is rather wide, ornamented by several small poresand presents a comma-shaped foramen. A connecting pore is generally present on Po. Plate 1 is irregularly rhomboidal, with longer apical right andantapical left sides; in its apical portion, it contacts Po and in its antapical portion it contacts plate Sa.The ventral pore along the margin between Plate 1' and 4' is generally not present. Plate 6'' is as wide as tall or slightly wider than tall. Plate 2'''' is generally transversely extended. Plate sp is pentagonal,and its length:width ratio is ∼ 1; a connecting pore is generally present on sp. In natural samples, cells can be arranged in chains or single. The cyst is ellipsoidal, with a granular dark brown content and is surrounded by a mucous layer.
