Scalloped edged mushroom

I like the shape of these mushrooms. Don't know what kind they are but I've been seeing them here, at the cabin, the past two years. Took Razzle for a walk. Enough of a breeze that the mosquitoes weren't too bad. Horse fly season has started though so I had my bug hat on. Monte went muskie fishing today. Had some action. Visited with our neighbor, Diane, for an hour.
