Mougeotia

 

a genus of widely distributed green algae of the order Zygnematales of the subclass Conjugatae. It includes about 80 species, which live in freshwater and often form a “scum.” The microscopic, unbranched threads of Mougeotia consist of a row of elongated cells, each of which contains one or two lamellate chromatophores with two or more pyrenoids. The algae reproduce from pieces of the threads or, less frequently, by nonmotile spores. After conjugation, they reproduce by means of zygotes.

These algal mats, primarily composed by Klebsormidium sp., also have Euglena mutabilis cells and minor filamentous Mougeotia sp., presenting a structure similar to the one reported by Stevens et al.

The diatoms Navicula, Nitzchia, Synedra, Eunotia, Pinnularia and the green algae Closterium, Mougeotia, and Ankistrodesmus were recurrent members of the algal community.
Although the organic laminations of Ordy Pond were not analyzed, similar laminations in the evaporite pan consisted of mats of two types of freshwater filamentous algae (possibly either Mougeotia or Spirogyra and Vaucheria).
