Pseudo-nitzschia delicatissima (P.T. Cleve) Heiden in Heiden & Kolbe, 1928
Pseudo-nitzschia delicatissima
Pseudo-nitzschia delicatissima. Light (A), SEM (B, C, D, E) and TEM (F, G, H) micrographs. (A, B and C) Scale bars = 10 µm. (D and F) Scale bars = 2 µm. (E) Scale bar = 0.1 µm. (G) Scale bar = 0.5 µm. (H) Scale bar = 0.2 µm (A) Part of a chain, lugol-preserved sample, DIC. (B) Colony with cells overlap, girdle view. (C) Whole valve, internal view. (D) Girdle view of “cut-off” valve ends. (E) Internal view of middle part of valve, showing larger central interspace, biseriate striae and central nodule. (F) The two ends of each valve site; note rounded shape and no difference in structure. (G) Cingular bands. (H) Poroids in two rows with hexagonal perforation pattern; note the different poroid shape and size.
