This one seems to have characteristics of Pediastrum and Eudorina.

Could it be Pandorina or Eudorina with a fungal parasite?

It could be some sort of parasite but I have never seen it before!

This is indeed a fungal parasite infecting a green algae. 2009 I found Gonium pectorale being infected:

Unfortunately I had a technical problem with my equipment back then and the pictures are pretty bad.

The swarmer looks like a short pin with a large pinhead. When they start to feed it looks like your photo. When they are finished the entire algae has the grey color.

This is parasite in the the group of fungi known as chytrids - maybe the genus Rhizophidium.[/u]
