Euastrum oblongum is a species of desmid, in the family Desmidiaceae. [1]

Euastrum oblongum consists of cells that are elliptic in outline, divide into two halves called semicells. The cells are typically 140–180 μm long and 65–85 μm wide. Semicells have a pair of basal lobes and a pair of lateral lobes, both with a shallow "pit" as to appear double-lobed. The apex is truncate with a deep notch. Semicells have a protuberance right above the isthmus (where the semicells are joined), as well as two more protuberances in the center of the cell and one in each lobe. [2]

Euastrum oblongum occurs in mesotrophic waters. [2] It has a widespread distribution, and has been recorded from around the world. [1]

Desmidiales, commonly called the desmids, are an order in the Charophyta, a division of green algae in which the land plants (Embryophyta) emerged. Desmids consist of single-celled microscopic green algae. Because desmids are highly symmetrical, attractive, and come in a diversity of forms, they are popular subjects for microscopists, both amateur and professional.
