Description

The white cap is hemispherical and white when young, but later flattens out up to 25 cm in diameter and becomes yellowish or tan. Its flesh is very thick. The gills are pinkish grey when young, and become brown with age. The spores measure 12 by 6 μm and are purplish-brown and almond-shaped. The stem is strong and thick, with a broad ring. It may measure 8 to 12 cm in height and up to 3 cm in diameter.

The flesh is white with a mild taste and a smell of aniseed, turning slowly orange when cut.

Similar species

There is a danger of confusing this mushroom with the deadly poisonous bulbous agaric Amanita phalloides and Amanita pantherina. Agaricus excellens is different by its taller and slimmer stipe which is striped lengthwise. Agaricus augustus does not have the pure white cap in young specimens.
