Looks like Beard algae.

Beard algae
Grows on plant leaves and is bright green. Individual strands have a very fine
texture but it grows in thick patches and looks just like a green beard. It
grows up to 4 cm. It cannot be removed mechanically. This does not indicate bad
water quality but grows very fast and overtakes the tank, making it a "bad"
alga. Can be eliminated with Simazine (Aquarium Pharmaceuticals
"Algae-Destroyer").
