Pseudo‐nitzschia pungens f: multiseries is raised in rank from form to species based on morphological, physiological, and genetic features. Distinctive details of the valve face striae, the valve mantle, and the girdle of P. pungens and P. multiseries are outlined. The nomenclatural history and the distribution of the two species and their relationship to other species of the genus are discussed. 

Morphological Variability of Pseudo-nitzschia pungens Clade I (Bacillariophyceae) in the Northwestern Adriatic Sea

An in-depth morphological analysis of P. pungens was carried out in both cultured strains isolated in different periods and field samples, revealing a surprisingly wide variability in a number of details, with both the gross morphology and ultrastructural levels deviating from the nominal P.pungens.

Integrative taxonomy of the Pseudo-nitzschia (Bacillariophyceae) populations in the NW Adriatic Sea, with a focus on a novel cryptic species in the P. delicatissima species complex

Results of the integrative taxonomic approach clearly revealed that P. arenysensis is a cryptic species within P. delicatissima species complex, and is closely related to P. werenysensis, which forms a subclade and a sister group in LSU and ITS phylogenies, respectively.

Identification of the marine diatom Pseudo-nitzschia multiseries (Bacillariophyceae) as a source of the toxin domoic acid in Algoa Bay, South Africa

Observations of a Pseudo-nitzschia species dominant in the plankton of Algoa Bay provide the first account of this toxic diatom in the coastal waters of South Africa.

A new diatom species P. hallegraeffii sp. nov. belonging to the toxic genus Pseudo-nitzschia (Bacillariophyceae) from the East Australian Current

A new species belonging to the toxin producing diatom genus Pseudo-nitzschia, P. hallegraeffii sp. nov., is delineated and described from the East Australian Current (EAC). Clonal cultures were

Pseudo-nitzschia seriata f. obtusa (Bacillariophyceae) raised in rank based on morphological, phylogenetic and distributional data

In growth studies under replete nutrient conditions, P. obtusa had a growth rate of 0.55–0.66 day−1 and an upper pH limit for growth of 9.1.

Toxic Pseudo-nitzschia multistriata (Bacillariophyceae) from the Gulf of Naples: morphology, toxin analysis and phylogenetic relationships with other Pseudo-nitzschia species

P. multistriata was the only one found to produce domoic acid among all the Pseudo-nitzschia species from the Gulf of Naples, and this finding raises the number of potentially toxic species in this genus to nine.

General shape and ultrastructure as taxonomic characters in diatoms: the case of the genus Bacteriastrum

Evidence that the general shape of the frustule is more informative than ultrastructural details, which are not significantly different from homologous characters of some Chaetoceros species, shows that also for some diatoms, as well as for many unicellular organisms, distinctive taxonomic characters have been chosen mainly opportunistically.

Pseudo‐nitzschia nanaoensis sp. nov. (Bacillariophyceae) from the Chinese coast of the South China Sea

This species is morphologically most similar to P. brasiliana, but differs by a denser arrangement of fibulae, interstriae, and poroids, as well as by the structure of the valvocopula and the narrow second band.

Inter- and intra-specific diversity of Pseudo-nitzschia (Bacillariophyceae) in the northeastern Mediterranean

Morphology and ITS2 phylogeny indicated that the level of diversity within the genus is higher than previously estimated (e.g. among P. delicatissima and P. galaxiae).

Nitzschia pungens Grunow f. multiseries Hasle: Observations of a known neurotoxic diatom

The morphology of the two forms is very similar, with overlapping measure­ ments of lengths, width, and number of costae in 10 pm, however, number of rows of poroid areolae or striae between costae are consistently different in culture when the two form are grown under similar conditions.
