Pseudoschroederia is a genus of green algae in the family Characiaceae. It is planktonic in freshwater habitats, and probably has a cosmopolitan distribution.[1] The genus Pseudoschroederia was circumscribed by Eberhard Hegewald and Eberhard Schnepf in 1986. The genus was distinguished from the similar Schroederia by being heteropolar and differing cell structure.[1] However, some authors do not consider the genera to be separate.[2]
Pseudoschroederia consists of solitary cells. Cells are spindle-shaped, straight or curved, 22โ84 ฮผm long. One end tapers into a spine-like point, while the other end is bluntly tipped. Cells contain one nucleus, a single parietal chloroplast and one or several pyrenoids with a starch sheath. Cells reproduce asexually by zoospores. Zoospores have two flagella and contractile vacuoles.[1] Species are distinguished from one another by their overall shape and size.[1]
