DRY WEATHER MUSHROOM... About 1.5 inches in dia. , in rock hard ground, not much rain this month, but this guy found enough moisture to come up. Many years ago, I had a large white pine tree, that  died , removed it and dug the main stump but cut off a lot of the feeder roots, ever since I find different looking  fungus in that area. Looks like a miniature puffball, however I don't think so.
