I have some brown/gold buttons you can have, if you come pick up. I also have some hairy mushrooms that are in a seriously light starved tank. They have shriveled up some, and lost their color, but are staying alive with almost zero light. You can have them if you want them, too.
I have to warn you that anything from my tank must be thoroughly inspected to be sure there are no flatworms before introducing it to your tank.
There is a slight gamble here, but it can be done, if you want.
