This is a fresh water algae. I have collected this algae from a small water Chanel.its macroscopic.leaves are arranged spirally
I am no expert on algae, but this fresh water alga appears to be Nitella sp., possibly Nitella allenii. It is what is called a Charophyte, a specialized group of green algae. A larger, similar genus is Chara.
