Amanita calyptroderma  G.F. Atk. & V.G. Ballen (1909)

Syn: Amanita lanei, Amanita calyptrata

This is one of the most vivacious and beautiful Amanitas of the Fall mushroom flora of California. It is also a sought after edible -- the Italians in the Bay Area call it Coccoli and it though to replace Amanita caesarea in their diet, although that the two mushrooms are not that close. There is a closely related species that fruits in the spring and was considered conspecific for more than a hundred years, but recently was described as Amanita vernicoccora.

Older fruitbodies display darker olive tinges. This may have led to a confusion on one of the descriptions.
