The gills are pinkish grey when young, and become brown with age.

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

It is possible to confuse this mushroom with dangerous amanitas such as A. phalloides and A. pantherina.

Agaricus excellens differs by its taller and slimmer stipe which is striped lengthwise.

Agaricus augustus does not have the pure white cap in young specimens.
