[/vc_column_text][vc_row_inner][vc_column_inner width=”2/3″][vc_gallery type=”image_grid” images=”3128,3129,3130″ css=””][/vc_column_inner][vc_column_inner width=”1/3″][vc_column_text css=””]Morphology

Trichomes unbranched, straight, ends of trichomes can be blunt or pointed; Cells usually longer than wide, width 4–6 μm; blue-green in color.

Toxins and toxicity

Microcystins, anatoxins. Study revealed salt acclimation of P. agardhii in producing microcystins (Vergalli et al., 2020).

Distribution and Occurrence

Fresh to brackish waters; a resilient and persistent species known to tolerate a wide range of temperatures and light intensities. In this study, this species was detected in salt marsh ponds in REF-1, REF-2, PGD-2, OMWM-1in winter, and OMWM-2 in November, January, April, and June.
