Chara grows well in MI ponds with hard water where it often develops crusty deposits on the stem-'leaves'. You are fortunate that it does not develop large expansive beds which is often the case with Chara. If the pond water is soft with low hardness then it is likely Nitella vary similar to Chara but growing in different water conditions. The main thing I dislike about Chara is it develops black smelly sediments underneath the weedbeds.
