Clint, for some reason, I can't zoom in on the photo. My first reaction is some kind of insect egg masses. You might try taking a sample down to your local county Extension office to see if anyone there can identify them. Call first, though, because Extension isn't what it used to be. They don't even do soil samples in Iowa anymore...they refer you to a commercial lab. But if you have an active bunch of Master Gardeners, they might still be doing plant clinics.
