Mougeotia

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.

Some genera of green filamentous algae, as Bulbochaete, Oedogonium, Mougeotia and Spirogyra, were distinguished only in vegetative groups, based on the cells diameter and length, due to the absence of reproductive structures in the analyzed individuals.

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).
