Like all stoneworts, the Baltic stonewort does not have true leaves or roots but has leaf-like branchlets in whorls around the stem and a mass of fine rhizoids that anchor the plant in sediment. Chara baltica is light bright olive green or dark to bright green in colour and has little calcium encrustation. It grows up to 90 cm in height and has small solitary acute spines scattered along the stem. The gaps between each whorl of branchlets (internodes) are 1-3 times as long as the branchlets themselves. Where present, male reproductive bodies are larger than 0.5 mm in diameter. It is anchored in mud or silt my translucent rhizoids and can give out an unpleasant odour.
