Looks old. Common lawn shroom from aroind here, they usually dont get this big due to the grillman boomers mowing their lawns all thr time

No idea what its actual scientific name is, with the cap so curled and old (white edges witj browning on the middle) with no scales, i assume it might be aome lepiota or smth, idk its cool looking and theres others growing there so idk jusr vibe on little mushroom friend
