ID for algae

[Spare time]

If you could id this that would be good

Looks like bryopsis
You will have to pull all you can by hand and then pull roots with a dental pick or small crochet needle and reduce white light intensity

Hmm I've never seen bryopsis look like this under a microscope before. I don't usually see bryopsis segmented like this in microscope pics.

Update

I am confident it is Chaetomorpha antennina
