Chara (Muskgrass; Stonewort) Missouri Department of Conservation

These aquatic algae look like regular vascular plants because they form stemlike, leaflike, and rootlike structures. Chara (pronounced care-uh or karr-uh) is gray green, with a crisp, gritty texture, a musky or garlicky odor, and whorls of needlelike structures that resemble leaves. The tiny dark balls that form on the whorls of plant are sporangia, which are spore-forming, reproductive structures. Removed from water, chara becomes grayish or white once it dries.
