A total of forty-three taxa were studied and described. The taxa belong to three orders, thirteen families and twenty two genera. Eighteen genera are new records for the country, as follows: Aphanothece, Aphanocapsa, Merismopedia, Gloeocapsa, Chroococcus, Entophysalis, Chlorogloea, Stanieria, Myxosarcina, Pleurocapsa, Pseudanabaena, Jaaginema, Geitlerinema, Porphyrosiphon, Spirulina, Leptolyngbya, Oscillatoria and Homoeothrix . Twelve species were found in distinctly different habitats from those from which the original type species were collected and described: Aphanocapsa cf. muscicola, Gloeocapsa cf. atrata, G. cf. arenaria, G. cf. punctata, Chroococcus cf. helveticus, C. cf. minor, C. cf. polyedriformis, Myxosarcina cf. concinna , cf. Jaaginema pseudogeminatum, Phormidium cf. priestley, P. cf. puteale and Homoeothrix cf. gracilis. One new combination is proposed [ Stanieria minima (Geitl.) Silva et Pienaar].
