Insect egg or Mushroom?
Hello, I am growing thyme bush in my indoor plant box for last 4 month. I just found green round egg like things covering the soil under the entire bush. Also found a yellow mushroom(?) next to the green eggs. I wonder what they are.

Hi - These are molds that grow on decaying organic matter in the potting soil.
These do not affect the health of plants growing in your plant box. You can remove the mold if you wish and discourage its return by keeping the soil surface as dry as possible without depriving your thyme of periodic watering. If it continues to be a problem, you can repot your plant into fresh potting soil and allow the soil surface to dry between waterings.
