That's not a recognizable eatable mushroom at least in my book. I have been mushroom picking since 8.
Never the less I do not think this one are lethal. Most likely you will be vomiting for a day or two, and feel like shit. So please DO NOT eat them.
Also mushrooms do not really have a root system of a plant, so they space is taken in minimal to non existent as mushroom do not grow too deep.
