We viewed your photos. These are not truffles. This looks like a type of puffball, a species of Scleroderma. Like other mushrooms it is living on dead organic matter in the soil. They eventually crack open. Often there is a dead tree root decomposing under the soil which is providing the nourishment it needs. It is not harmful nor is there anything you can spray or apply to get rid of it.
