That is a type of hair algae growing on your Marimo there. I get this sometimes too if one decides to float too close to the light source. Just pull off the "hairy" part, and do as other have suggested above and squeeze it out and roll it around a bit. If you can move it to a darker part of the tank that should take care of your problem.

Remember that the tank your fish lives in is his or her's whole world. Ask yourself this question, and answer it honestly: would you choose to live there?

OK so I finally had time to clean this tank today. The "hair" is actually part of the marimo, not something growing ON the marimo. I squeezed it all out and rinsed it and rolled it. The photo shows it floating around in the cleaned tank before it finally sank

I'm assuming this is how it grows?

It is in a low light tank with a few hours of direct sunlight every day. However I placed them in the other side of the tank so now it will get less direct sunlight.
