n.
An edible species of mushroom (Agaricus campestris).
n.
An edible fungus (Agaricus campestris), having a white stalk which bears a convex or oven flattish expanded portion called the pileus. This is whitish and silky or somewhat scaly above, and bears on the under side radiating gills which are at first flesh-colored, but gradually become brown. The plant grows in rich pastures and is proverbial for rapidity of growth and shortness of duration. It has a pleasant smell, and is largely used as food. It is also cultivated from spawn.
n.
Any large fungus, especially one of the genus Agaricus; a toadstool. Several species are edible; but many are very poisonous.
n.
An old name for several species of Polyporus, corky fungi growing on decaying wood.
n.
An amorphous, gummy carbohydrate, found in Gelidium, agar-agar, and other seaweeds.
n.
A name given to many umbrella-shaped fungi, mostly of the genus Agaricus. The species are almost numberless. They grow on decaying organic matter.
n.
A solid crystalline substance, C5H13NO2, found in the toadstool (Agaricus muscarius), and in putrid fish. It is a typical ptomaine, and a violent poison.

n.
A piece of tinder made of agaric, used in firing the powder hose or train of a mine.
