Description Trichomes free-floating in plankton, solitary, straight or slightly arcuate, up to more than 1.5 mm long, towards ends slightly attenuated, slightly to distinctly constricted at the cross-walls. Cells cylindrical, isodiametric up to 3 x longer than wide, with pale blue-green content with aerotopes, (2.5) 3.5 up to 15 x (2.4) 3-5.1 μm; terminal cells up to 3-7 x longer than wide (up to 30 μm long), 3-5 μm wide, narrowed, at the ends rounded-pointed. Heterocytes spherical to ellipsoidal, (4.4) 6.1-12 x (4.8) 5-8.5 μm. Akinetes widely oval, intercalary, mostly distant, rarely joined to heterocytes, (13.6) 18-27.8 x 10.8-15.1 μm, with yellow or brownish exospore. [details]

Description Trichomes free-floating in plankton, solitary, straight or slightly arcuate, up to more than 1.5 mm long, towards ends slightly attenuated, slightly to distinctly constricted at the cross-walls. Cells cylindrical, isodiametric up to 3 x longer than wide, with pale blue-green content with aerotopes, (2.5) 3.5 up to 15 x (2.4) 3-5.1 μm; terminal cells up to 3-7 x longer than wide (up to 30 μm long), 3-5 μm wide, narrowed, at the ends rounded-pointed. Heterocytes spherical to ellipsoidal, (4.4) 6.1-12 x (4.8) 5-8.5 μm. Akinetes widely oval, intercalary, mostly distant, rarely joined to heterocytes, (13.6) 18-27.8 x 10.8-15.1 μm, with yellow or brownish exospore. [details]

Harmful effect Strains of this species isolated in culture were found to produce cylindrospermopsin (Banker et al. 1997, Yilmaz et al. 2008, Stüken et al. 2009, Ballot et al. 2011, Barón-Sola et al. 2017). [details]

Identification From Russia (central Ural) was described f. brevicellum Ulomskij 1956 with cells only 3.4-4.5 μm long- cf. Anabaena bergii; records from Spain and from Australia should be confirmed (slightly different dimensions, identity of genotypes?). — Cf. Sukenik & al. (2012). [details]

Remark Heterocysts, nitrogen fixing filamentous form [details]
