Okay - Some species of Chara do not have a strong odor. See those bumps on many of the individual 'leaf-lets' or needle-like leaves? IMO those are the "fruits" that are egg bearing cases called oogonia and about the size of pin points. They are what makes the needle like leaves have jagged edges. If one looks very closely the stems are divided into joints of the stem and not tubular and no connective tissue which technically makes them a form of algae. Most of the Chara species live in water with higher carbonates. Chara has a soft water counterpart called Nitella.
