Distribution Widely distributed in temperate and subtropical waters. A few findings from tropical waters. See list of distribution in Hasle (2002): Are most of the domoic acid-producing species of the diatom genus Pseudo-nitzschia cosmopolites? Harmful Algae 1: 137-146. [details]
Harmful effect Produces domoic acid and isodomoic acid C. See Garrison et al (1992) and Holland et al (2005) [details]
Identification P. australis is characteristic by the wide lanceolate valve (5,5-8,0µm in width), the lack of a central nodule and two rows of poroids, with 4-5 poroids in 1µm. The valve is sometimes asymmetrical, sometimes not.
*The most closely related species are P. seriata and P. obtusa, which differ by having 3-4 rows of poroids and denser poroids (P. seriata) or by having less wider valve and more densely spaced poroids (P. obtusa).
Verified sequences:
LSU rDNA: AF417651
ITS rDNA: AY257842
Electron microscopy or molecular sequences are needed for correct identification.
