Notes:

The fool's mushroom (Amanita verna) also known as the spring destroying angel or death angel, is a close relative of Amanita phalloides, the death cap and a member of the mushroom genus Amanita. Amanita verna, like its close relative, belongs to the subfamily Phalloideae. The fool's mushroom is pure white, all the way to the gills and the stem. This fungus, like all amanitas, has a volva. The fool's mushroom's cap is 5–10 centimetres (2–4 in) wide, and is about the same height. ---This mushroom's lamellae is free and white, and the volva is bag-like and large. Its annulus is white and membranous, and A. verna also does not react with potassium hydroxide solution, unlike its relative Amanita virosa. The mushroom's spores are smooth and elliptical
