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]
