Hygrocybe conica is a species of agaric (gilled mushroom) in the family Hygrophoraceae. In the UK it has been given the recommended English name of blackening waxcap, since all parts of the basidiocarp (fruit body) blacken with age. In North America it is commonly known as the witch's hat, conical wax cap or conical slimy cap.
