03F8F15A1573FFD8FF59B72EFC6BF363.taxon	discussion	Remark: This species was included in the family Oocystaceae, order Chlorococcales by Komarek and Fott (1983), but was moved to the family Oocystaceae, order Chlorellales, class Trebouxiophyceae by Guiry and Guiry (2016). Hindak (1980) included this species in Tetrachlorella Korshikov as a synonym, but Komarek and Fott (1983) transferred it into Fotterella from Tetrachlorella, which has solitary or architectonie of cells in colonies.	en	Kim, Yong Jae (2017): New records of coccoid green algae in Korea.

03F8F15A1573FFDBFCB0B7ECFD95F196.taxon	discussion	Remark: This species was first described by Kol (1937), but has not subsequently been clearly identified. Komárek and Fott (1983) reported this species but did not provide descriptions or original figures (only presented the figure of Kol, 1968). This species was initially classified in the family Oocystaceae, order Chlorococcales by Komárek and Fott (1983), but Guiry and Guiry (2016) included it in the family Oocystaceae and order Chlorellales in the class Trebouxiphyceae.	en	Kim, Yong Jae (2017): New records of coccoid green algae in Korea.

03F8F15A1570FFDAFCDEB558FEEAF5E6.taxon	description	Description: This species is free floating and globular or semiglobular in shape.

03F8F15A1570FFDAFCDEB558FEEAF5E6.taxon	discussion	Remark: This species is unicellular or solitary, but has four autospores in a thick mother cell wall formed during asexual reproduction. Shubert (2003) reported this species in phytoplankton, and Komárek and Fott (1983) reported it from a highland bog. The alveoli in the thick wall is a distinctive characteristic for identification of this species. It was initially classified in the family Chlorellaceae, order Chlorococcales in the class Chlorophyceae, but Guiry and Guiry (2016) moved this species to the family Oocystaceae, order Chlorellales in the class Trebouxiophyceae.	en	Kim, Yong Jae (2017): New records of coccoid green algae in Korea.

03F8F15A1571FFDAFF59B66FFB31F718.taxon	discussion	Remark: This species was first described from a swamp in Caen, France by Dangeard (1889). Showalter (1952) also collected this species from filamentous algae and other submerged or floating aquatic plants in lakes and ponds in Kansas, USA (not from the plankton). In the present study it was collected in plankton nets at shallow depths off the shore of Chukdong reservoir. This species was included in the family Chlorellaceae, order Chlorococcales, class Chlorophyceae by Komárek and Fott (1983), but Guiry and Guiry (2016) placed it in the family Tetrasporaceae, order Chlamydomonadales in the class Chlorophyceae. In this study it is classified according to Komárek and Fott (1983).	en	Kim, Yong Jae (2017): New records of coccoid green algae in Korea.

03F8F15A1571FFDAFCB0B3A5FA02F0CC.taxon	discussion	Remark: This species has similarities with the genus Franceia, which has several fine spines on the cell surface, but it differs in having a granulated cell wall surface. The genus Siderocystopsis also differs from the genus Siderocelis both by the presence of numerous fine and long spines, and by the presence of unique fine spines at the periphery of parts of the cell wall of the mother cell, following the release of autospores (Hindak, 1977). Sidercoystis fusca was described by Korshikov (1953) and placed in the family Oocystaceae. Swale (1964) replaced the invalid genus name Siderocystis by Siderocystopsis, and Ettl and Komárek (1982) transferred the alga to the family Micractiniaceae. The bristles and cell wall structure of Siderocystopsis are different from Micractinium that Siderocystopsis were not due to a cell wall structure having intersecting cellulose fibrils, and in older cells having two chloroplasts each containing a single pyrenoidg. (Hegewald and Schnepf, 1984). The description of Golenkinia punctifera by Bolochonzew (1903) is similar to the description and illustration of Siderocystopsis fusca. However, Hegewald and Schnepf (1984) merged G. punctifera into Siderocystopsis punctifera as a basionym. Guiry and Guiry (2016) noted that this species is currently regarded as S. punctifera. It is need to rearrangement from S. fusca to S. punctifera.	en	Kim, Yong Jae (2017): New records of coccoid green algae in Korea.

03F8F15A1571FFDCFCB0B511FE5CF79B.taxon	discussion	Remark: Siderocelis oblonga is firstly described by Naumann (1921) as Chlorella (Siderocelis) oblonga. Fott (1934) merged C. oblong into Siderocelis oblonga as a basionym. Hindak (1988) reported the new species Siderocelopsis oblonga as a basionym that is C. oblonga, and merged Siderocelis oblonga into Siderocelopsis oblonga as a synonym. Guiry and Guiry (2016) suggest that Siderocelis oblonga is currently accepted taxonomically and Siderocelopsis oblonga is regarded as a taxonomic synonym of Siderocelis oblonga. Therefore, it is classified to Siderocelis oblonga in this study. Naumann (1921), Fott (1934), Komárek and Fott (1983), and Hindak (1988) classified to the family Chlorellaceae, order Chlorococcales in class Chlorophyceae, but Guiry and Guiry (2016) replaced to the family Chlorellaceae, order Chlorellales in class Trebouxiophycaee. It needs to rearrangement that this species place into class Chlorophyceae or Trebouxiophyceae.	en	Kim, Yong Jae (2017): New records of coccoid green algae in Korea.

03F8F15A1577FFDCFF59B76DFC07F527.taxon	discussion	Remark: The genus Pachycladon was originally described from Palisades Interstate Park in New York by Smith (1924). Smith (1924) described Pachycladon umbrinus as a new species, but Silva (1970) renamed the genus Pachycladon to the new genus Pachycladella, and merged Pachycladon umbrius into Pachycladella umbrina as a basionym. Fott and Kovacik (1975) includ- ed P. umbrina into Treubaria umbrina as a synonym. Treubaria umbrina has similarities to the genus Treubaria, but differs in cell shape, the nature of the appendages, and the chloroplast (Smith, 1950). Therefore, it is classified as Pachycladella umbrina because there is no controversy with respect to the differences between the two genera.	en	Kim, Yong Jae (2017): New records of coccoid green algae in Korea.

03F8F15A1577FFDFFCB0B16AFD21F4E4.taxon	discussion	Remark: This species was originally classified as Pachycladon zatoriensis by Bednarz and Mrozinska-Webb (1971), but was transferred to the genus Pachycladella and merged with Pachycladon zatoriensis into Pachycladella zatoriensis as a basionym by Komárek (1979). Reymond et al. (1992) described that this species is very morphologically similar to P. umbrina, but differentiated because the four bifurcated appendages decorating this unicell are located in a cruciate or tetrahedral position. The original description of the genus and its type species Pachycladella umbrina by Smith (1924) is very clear in showing that the cell bears four quadrately (very rarely pyramidally) arranged appendages. This indicates that all species belonging to this genus have appendages arranged in a cruciate position, and rarely tetrahedrally. Reymond et al. (1992) suggested that this is a speciesrather than genus-level feature: only Pachycladella umbrina has appendages in a cruciate disposition, whereas Pachycladon zatoriensis has appendages located tetrahedrally. Reymond et al. (1992; 1993) also showed clearly that these taxa separate into two main categories: cells having appendages located in a cruciate position (Pachycladella umbrina), and cells having appendages located in a tetrahedral position (Pachycladon zatoriensis). It was also shown that the length of the appendages, and the cell shape and diameter varies markedly among specimens in the same collection, based on transmission electron microscopy (Reymond et al., 1992; 1993).	en	Kim, Yong Jae (2017): New records of coccoid green algae in Korea.

Hajdu (1975) reported Coenocystis estheriana as the new species and merged S. estheriana into C. estheriana. However, any other species in the family Radiococcaceae were not granules on the cell wall surface.

03F8F15A1574FFDFFF67B169FBC5F226.taxon	discussion	Remark: Smith (1926) did not agree with the description by Schmidle (1900) that there was no gelatinous sheath surrounding the coenobia and filling the central space. He also described differences from the iconotype of the species, reporting cells being ellipsoid to square and slightly bent outward or concave, and lacking projections at the ends of the outer side. This species was originally described as C. fenestrata var. mucronata by Smith (1926). However, Komárek (1974) transferred C. fenestrata var. mucronata to C. mucronata as a basionym. Smith (1926), Komárek and Fott (1983) originally classified this species in the family Scenedesmaceae, order Chlorococcales in the class Chlorophyceae, but Guiry and Guiry (2016) placed in the family Trebouxiophyceae incertae sedi, order Trebouxiophyceae ordo incertae sedi, in the class Trebouxiophycae.
