Species | |
Pseudopediastrum is a genus of green algae in the family Hydrodictyaceae.[1] It is very common in freshwater regions throughout the world.[2]
Description
Pseudopediastrum forms flat colonies, termed
coenobia, of cells in powers of two, usually four, eight, 16, or 32. Coenobia are disc-shaped in outline, and marginal cells are drawn out into two lobes or points. Cells have one chloroplast filling the cell, each with a single pyrenoid.[3] In most species, the cells are contiguous without gaps between them, but this is not always the case. Important identifying characteristics include cell shape and cell wall granulation.[4]
Taxonomy
In 2005,
monophyletic, in particular the morphologically diverse species Pseudopediastrum boryanum. Therefore, the genus is still in need of a revision.[6]
