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]
