Aphanizomenon flos-aquae
Bloom former in the shape of elongated half-moon clusters. Bloom looked like pea-soup, of green paint with visible structure differ from Microcyscis/Dolichospermum blooms.Clusters were several millimetres long. Microscopically filaments were clustering together in the typical Aphanizomenon-like way. Apical cells within the cluster were containing less aerotopes and were very elongated to compare with regular vegetative cells, length of apical cells: up to 35 micrometers. Apical cell appeared to be narrowed than regular cells, 5 micrometers. Intercalary heterocytes were observed, brownish by color with clear pores, L:10-12 micrometers, W:6.4-7.6 micrometers. Also, elongated akinetes observed with granular texture and slightly different color from regular cells, L:26-70 micrometers, W: 6-7 micrometers. Vegetative cell slightly constricted with bunch of aerotopes, W:6-6.4 micrometers, L:same as L, slightly longer than wide.
