This looks like a type of fungus in the Genus Scleroderma. It is a type of puffball, a mushroom. This is not harmful to your lawn, nor is there anything you can spray or apply to get rid of it. Like other mushrooms, which are fungi, it is living on dead organic matter in the soil. Often there is a dead tree root decomposing under the soil which is providing the nourishment it needs. As the root breaks down, the fungi will no longer be able to live on it. All of that is going on out of sight under the ground. The puffball which rises up (the typical mushroom we think of, though this one is a big round ball) is actually a reproductive part. It comes up when the conditions are favorable (usually wet), lives a few days and produces spores, and then breaks down. No control is necessary.

We still think so. It is a common enough occurrance this time of year when conditions are right. There are many, many fungi however and we don't have a mycologist on staff. There are multiple species, and you can see them and search photos of other similar types, at this site from the Maryland Biodiversity Project:
