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. [ABSTRACT FROM AUTHOR]

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.

A study on Chlorococcal algae was carried out at 33 stations (ponds, swamps, reservoirs, lakes and rivers) from May 2009 to January 2013. The families Hydrodictyaceae and Coelastraceae of order Chlorococcales were investigated, including 5 genera, 29 species, and 17 varieties. Among them, 8 taxa were newly recorded for Korea; 1) Family Hydrodictyaceae: Pediastrum asymmetricum, P. boryanum var. campanulatum, 2) Family Coelastraceae : Actinastrum aciculare, A. hantzschii var. subtile, Coelastrum indicum, C. microporum var. octaedricum, C. morus, C. pulchrum.

The present study summarized the occurrence, distribution and autecology about 31 taxa of the green algae (Chlorophytes) collected from several swamps, reservoir and highland wet-lands in the South Korea from 2010 to 2013. This paper deals with a total 31 taxa including of 26 genera which are recorded for the first time in Korea. Among these algae, 18 genera including Pyrobotrys Arnoldi, Volvulina Playfair, Dicellula Svirenko, Echinocoleum Jao & Lee, Hofmania Chodat, Gloeotila Kützing, Tetrachlorella Korschikov, Botryospherella P.C.Silva etc., were newly recorded in Korean fresh-water algal flora.
