Well, you've got some mushroom spores in the soil. I'm guessing either this potting soil isn't very fresh, as in, it was used for another plant, or you've picked up alot of small seeds and spores from putting the plant outside. You can remove the shrooms and little plants growing in the soil. Have you thought about trying to clone a branch or two? If it's flowering, there might be some trouble cloning but unless you plan on getting other seeds, cloning might be worth a shot.
