I need help in identification of this structure

I found such strange structures inside Spirogyra filaments and I do not know what it is. So, if there is anybody who could help me I will be very grateful

Could it be a diploid zygospore, as here?

All Spirogyra zygospores I've seen are oval and green because they retain the chloroplasts although without the spiral shape. No idea, but could it be an amoeba inside the cell?

No, it is not any amoeba. It did not move at all and it was connected to the Spirogyra cell walls. I could see it in many Spirogyra filaments.

Hi Marek,

I'm not an expert but (famous last words

)..was thinking about an animal structure, if it would be vegetable I'd expected the cell walls to be thicker.
Given the size it MIGHT be an animal lifeform in one of its first stages, still growing and developing. The fact that you found more of these in your sample, that they are clearly attached to the algae and they are not showing any movement, do not contradict this. Maybe you could keep it for a while and see what happens.

Something else:
CONGRATULATIONS with your 16th place in this years small world photomicrography contest,I cannot remember this one from the forum but it shows a creative, refreshing approach: Well done
