Codosiga botrytis (Ehrenberg, 1838) Kent, 1880 (ref. ID; 4907) reported year? (ref. ID; 3343) reported author and year? (ref. ID; 2659)
Description; Cells without stalk and collar 7.5-10 um long. Cell globular or slightly elongated, length:breadth ratio 1 to 1.5, usually attached to substrate by a stalk of variable length, from nearly absent up to 5 times cell length. Nucleus in anterior end, several posterior vacuoles. One single flagellum up to 3 times cell length surrounded by single collar. Collar about as long as cell. Collar and flagellum sometimes resorbed. Swimming specimens usually with several tiny pseudopodia. Only occasionally more than one cell on each stalk. Either sessile, attached by stalk with beating flagellum or swimming with flagellum directed posteriorly. (ref. ID; 4907)
Comments; The organism described above is in good agreement with the concept of Codosiga botrytis as outline by Hibberd (1975) and Vors (1992), but differs from the concept of Ehrenberg (1838) and Kent (1880). The cells depicted by Ehrenberg (1838) and Kent (1880) have thicker stalks and occur in clusters. Hibberd (1975) observed that the majority of cells occurred singly in some samples, while clusters of cells were more common in later collections from the same locality. Clusters will probably only occur when the flagellates grow undisturbed for a longer period, which was not the case in the examined soil samples. This genus is consequently in need of review, but at present we accept the concept of Hibberd (1975) and Vors (1992) in applying a species name. (ref. ID; 4907)
