Closterium moniliferum Ehrenberg ex Ralfs 1848
Most likely ID: n.a.
Basionym: n.a.
Add’l Synonyms: Lunulina monilifera Bory 1824
Arthrodia monilifera (Ralfs) Kuntze 1891
Closterium garoetianum C.Bernard 1908
Description: The cells are (4)–5–7–(8) times longer than they are wide, evenly curved and continuously narrowing towards the rounded cell ends. The cell wall is delicately striated to almost smooth, without girdle bands. The pyrenoids are arranged more or less in a row along the cell axis, which, in addition to the smaller dimensions, distinguishes this species from the morphologically similar Closterium ehrenbergii. The pyrenoids are numerous and scattered.
Dimension: Length (170)–200–350–(450) µm, width (28)–35–55–(70) µm.
Occurrence: Widely found in ponds and lakes, backwaters and the like, occasionally also in plankton.
