Mushrooms.They spring up out of the ground in bunches, coming, seemingly out of nothing. You crush them, and a burst of spores will fly out. Some are good to eat, while others will kill you if you eat them. Mysterious, they seem, coming and going without warning, like a cat in the night. Magical, they appear, sometimes forming in circles like a ring stools that fairies had sat on early that morning. These oddities are one of natures mysteries.
