Client's Request:  Yesterday I found what appear to be hundreds of white tiny eggs on my raised bed soil. I'm attaching a photo. Can you tell me what they are and if I should remove them? Thank you!

Help Desk Response: Thank you for contacting the UC Master Gardener Program Help Desk and for sending those good photos of the little white things on your soil. As I said in our conversation earlier today, they look like a type of slime mold and are not harmful to your garden. They eat bacteria and fungal spores, as well as organic debris and are not harmful to your garden They come in a wide variety of colors, shapes and sizes. 

Slime molds are pretty interesting organisms. They start out as individual cells and join together into a moving, sometimes pulsating mass. I found a couple of articles and videos about slime molds you might find of interest:

Happy gardening! Please let us know if you have further questions.
