Leucoagaricus leucothites, commonly known as the smooth parasol, woman on motorcycle,[2] ma'am on motorcycle,[3] white dapperling, or white agaricus mushroom, is a species of agaric fungus. The species was originally described as Agaricus leucothites by Carlo Vittadini in 1835, and bears similarity to species of that genus.[4] Solomon Wasser transferred it to Leucoagaricus in 1977.[5] While sometimes regarded as edible,[6] the species is suspected of being poisonous due to gastric-upset-causing toxins.[7] It could also be confused with the deadly Amanita ocreata.[6]

The mushroom's cap is 4 to 15 cm wide,[6] is granular, white or gray-brown in color then sometimes grayish or pinkish.[4] The flesh may bruise yellowish and the gills reddish.[4] The stipe is 5 to 12 cm long, commonly with a wide base, and bruising yellow or brown.[6] A ring is usually present.[4] The spores are white, smooth, and elliptical.[6]

It generally appears in civilized areas such as gardens and parks, but sometimes is found in forests.[4]
