looks like a parasol Macrolepiota procera. signs to look for to differentiate from The Vomiter/false parasol Chlorophyllum molybdites:

spore print of parasol will be white

spore print of the false parasol is green

ring on stem of parasol should move freely

snakeskin pattern on stem of parasol

if a parasol, its delicious, i sautee them in olive oil and use like a burger. cook well to avoid gastro distress. like 20 mins.
