A study on fresh-water green coccoid algae was carried out at ponds, swamps, reservoirs, lakes and rivers (290 sites) from May 2011 to January 2014. In this study, 4 genera and 13 taxa of the family Radiococaceae having the remnants of cell wall existing for a long time in the colonial gelatinous envelope are classified and identified from 24 sites. Many taxa of this family, however, have not been recorded in Korea yet. Of these 13 taxa, 5 taxa are newly recorded in Korea by this study: 1) Schizochlamydella solitaria, 2) Thorakochloris planktonica, 3) Radiococcus bavaricus, 4) R. nimbatus, and 5) R. planktonicus.

This study was carried out on freshwater chlorococcal green algae in ponds, swamps, reservoirs, lakes and rivers (290 sites) from May 2012 to January 2014. The family Radiococaceae was identified and classified into 3 genera, 12 species and 1 variety at 23 sites. These taxa were Eutetramorus. nygaardii, E. tetraporus, E. planctonicus, E. fottii, E. globosus, E. polycoccus, Coenocystis planctonica, C. planctonica var. hercynica, C. micrococca, C. subcylindrica, Gloeocystis baneergattensis, G. papuana, and G. polydermatica. These taxa may or not had remnants of the cell wall in the colonial gelatinous envelope for a short time. Of these, 2 taxa are newly recorded in Korea from this study: 1) C. micrococca and 2) G. polydermatica.
