I ripped them out all along the edge of the lawn on one of my accounts. I don't know if it's insect eggs or some type of fungus. One of them appeared to have a little hole in it. This same lawn had problems in June with some type of insect tunneling making slight bumps in the lawn, (No it's not a gopher). I'm just embarressed because it was the first time that I did not know the answer of what these things are. Anyone have a clue?
