Anyone ID what this stuff is? Good? Or try and get rid of it?

Too blue and unfocused on my end for an accurate ID.
Maybe white?

Looks like this stuff
Red dictoya?

Gracilaria was my guess on the first one.

Coelarthrum is my guess on the second one.

But, like uncle, pics too blue and fuzzy for me to do more than guess.

It’s on a piece of paper

Looks like a red macro algae based on this pic I sent into AI

Looks like Gracilaria. Good and herbivores will eat it.
