From regional or thematic species database
Trusted: edited by a thematic editorClassification In phylogenetic analyses, P. multiseries clusters together with P. pungens as sister taxon; firmly within a larger cluster of Pseudo-nitzschia species (e.g. Lundholm et al 2002) [details]

Trusted: edited by a thematic editorDistribution P. multiseries is globally distributed from subpolar to subtropical waters: In Atlantic waters of Europe, North and South America and in Pacific waters of Northeast Asia and North America i.e. from ca. 65°N-15°N and 30°S -50°S  [details]

Trusted: edited by a thematic editorHarmful effect P. multiseries produces domoic acid, and was the cause of the major harmful event in Canada 1987 caused by Amnesic Shellfish Poisoning (ASP), affecting more than 100 persons of which 3-4 died (Bates et al. 1989).
Since this incident, toxin producing strains of P. multiseries has been reported from globally distributed strains e.g. France (Amzil et al. 2001), Japan (Kotaki et al. 1999) and Canada (Evans et al. 2004).

Domoic acid has been found in amounts up to 21 pg/cell in cultured strains (e.g. Bates et al 1989, Douglas & Bates 1992)
 [details]

Trusted: edited by a thematic editorIdentification P. multiseries is morphologically similar to P. pungens, but can be differentiated by having 3-4 rows of poroids (P. pungens has 2), a poroid density of 5-7 (P. pungens has 2-5), and partly by a higher density of band striae. (Hasle 1995, Hasle et al. 1996). Distinguishing between the two species usually requires electron microscopy or molecular data.
 [details]

Trusted: edited by a thematic editorMorphology Cells lanceolate in valve view, lanceolate-linear in girdle view, sharply pointed ends
Valve width 3.4-4.5µm
Valve face with 10-15 striae and fibulae in 10 µm.
No central nodule (and interspace)
Each stria with 3-4 rows of poroids, each with 5-7 poroids in 1µm
Striated bands, valvocopula with 19-30 striae in 10µm
 [details]

Trusted: edited by a thematic editorReproduction Sexual reproduction of P. multiseries has been described by Davidovich & Bates (1998) [details]
