Hi everyone. I would really appreciate a second opinion about these freshwater cyanobacteria, at least about their genera. Any help is extremely appreciated! Thanks in advance!
Tentatively 1, 3 and 5 look like the stages of the same genus of the Chlorococcalean green alga and 2 and4 may be aphanothecoid forms of Cyanobacteria but non of them is Microcystis. Your photographs are not clear. If you can share more photographs then we can help you.
