A bog is a special kind of wetland that accumulates plant material called peat. There are many different kinds of bogs, but most are good habitat for green algae.

Bogs are a unique habitat that supports a wide range of organisms, including many green algae. Green algae can be found in the open water of bogs, or growing among the soaked plant material at the edges. Collecting from different parts of the bog will often yield different species.

Most bogs contain many species of conjugating green algae (Zygnematophyceae), especially desmids. Mougeotia is one filamentous form commonly found in bogs along with unicellular desmids like Staurastrum and Xanthidium. Many bogs also contain flagellate green algae like Pandorina mora.
