Question
Today my kids came to me to have me look at something growing in our lawn. It looked like a broken egg was not. When I dug it out of the ground the roots almost looked like a brain. It had clear slime all on it and what looked like a yolk. The funny thing is that my husband mowed the lawn yesterday and it was not there. I tried to look it up but can find nothing. What do you think it is?

Answer
As far as I can find out it is a type of slime mold. Check out this site:
