Mougeotia Agardh
	Named for the Alsatian physician and botanist Jean Baptiste Mougeot
	Mougeotia has long, unbranched, uniseriate filaments. Sometimes rhizoid-like growths from the basal cells allow the filaments to attach to the substrate. The cells are usually cylindrical and are at least four times longer than broad. The nucleus is normally located next to the chloroplasts in the center of the cell.   Like Mesotaenium, each Mougeotia cell has one or two plate-like chloroplasts that can rotate to maximize light levels. Each chloroplast has multiple pyrenoids that are either scattered or arranged in a row. Sensory pigments detect the wavelength and position of the light. A transducer translates this information into a chemical code that signals a mechanical effector to move the chloroplast, much like a mechanized solar panel. Molecular data has shown that Mougeotia and Mesotaenium are closely related, as is evident by their similar chloroplast morphology. Small vacuoles scattered throughout the cells contain phenolic compounds that most likely offer protection from herbivores.
