Marimo ball turned brown

Ive had a marimo ball in my tank for a few years. Its 3-4 inches long, but has turned totally brown. There are other, smaller ones in the tank as well, but they are still nice and green. Any ideas what would make the one turn brown? I read somewhere that cutting it up can sometimes revive them. Anyone tried that and had it work? Any way to get it to green it up again?

I have a 26 gallon bowfront, no fertalizers except what they get from the fish. Low light, no CO2, tank is 72 degrees. I take them out and rinse them every few months.
