How are pale toadstool and champignon similar and different?

The champignon and the toadstool have the same color cap and leg. A pale grebe is a poisonous mushroom, its use in food due to an error in the definition can end in death. In order not to confuse a champignon with a pale toadstool, you need to know that a pale toadstool has a pure white hat on the bottom, while a champignon has a pink or light purple color. A toadstool has a sac at the base of the mushroom leg, but a champignon does not have such an element, and a mushroom’s leg is thicker than that of a toadstool. Even in a toadstool, the leg gradually expands downward and enters the bag, while in the champignon it is uniform.
