Extract from Wikipedia article: Leucocoprinus birnbaumii is a species of gilled mushroom in the family Agaricaceae. It is common in the tropics and subtropics, but in temperate regions frequently occurs in greenhouses and flowerpots, hence its common names of flowerpot parasol and plantpot dapperling. The fruit body is mildly poisonous, if consumed in large quantities.
