From the Greek rhabdos –a rod, and gloios- glutinous, gelatinous, sticky.
|
||||
Classification: |
||||
Dactylococcopsis Hansgirg 1888; 10 of 55 species descriptions are currently accepted taxonomically (Guiry and Guiy 2013).Order Chroococcales; Family Chroococcaceae
|
||||
Morphology: |
||||
|
Colonies of fusiform cells without distinct sheath. D. salina forms gas vesicles (‘vacuoles’) (Walsby et al. 1983).
|
||||
Similar genera: |
||||
|
Rhabdogloea is a synonym. Geitler (1932) makes reference to Ankistrodesmus (eukaryotic colonial Chlorophyte) as sufficiently similar to be easily mistaken for Dactylococcopsis.
|
||||
Habitat: |
||||
|
Most species are planktonic in lakes and reservoirs. Some are found within the mucilage of Microcystis colonies. |
