Amanita citrina

Known as the false death cap, or Citron Amanita, Amanita citrina (previously also known as Amanita mappa), is a basidiomycotic mushroom, one of many in the genus Amanita. It grows in silicate soil in the summer and autumn months. It bears a pale yellow or sometimes white cap, with white stem, ring and volva. Though it is not poisonous, its similarity to the lethal death cap (Amanita phalloides) precludes its use in cooking.
