Hello! I have some African violets and Streptocarpus plants that are generally healthy, but seem to have some sort of fungus in the soil and at the base of the leaves. When I was using self watering pots, it would collect at the base of the pots (where the water wicked up into the soil). It smells strongly of mushrooms, and is pale yellow in color. As you can see from the attached pictures, the fungus (if that is what it is) consists of little round balls (almost like little eggs)... I have tried repotting all my plants, sterilizing my pots with a light bleach solution, spraying with a fungicide, but I can't seem to get rid of this stuff. Does anybody know what it is, and how to get rid of it?
