This gray-green branched algae is oftentimes mistaken for a plant
because it has stem and leaf-like structures. Two key features that
differentiate Chara Algae from other aquatic plants are its smell and
texture. Chara Algae has a foul almost garlic-like scent that becomes
more prominent when it is crushed. The texture of this algae is very
grainy, and when left in the sun for just a few hours will turn ashy and
grey. In addition, Chara Algae will not grow out of the water and doesn’t
flower like most plants.
