There are numerous versions or species of Nostoc and other similar algae that can develop gelatinous balls. Nostoc can have around 120 species. Other algae with gelatinous forming balls includes Rivularia and Nodularia, each with many species. There is even a green algae that forms balls. Best way to see what's inside the gelatinous ball is crush, smear one on a microscope slide and look at it with appropriate magnification. Removal of the weeds with the growth is one option. I would not try and use chemical treatment on it because the gelatinous coating will prevent chemical penetration.
