Amanita caesarea

Amanita caesarea (Caesar's Mushroom), is an edible mushroom in family Amanitaceae, native to southern Europe. The common name comes from its being a favorite of the Roman emperors, which took the name Caesar (originally a family name) as a title. Other common names include Royal Amanita, Amanite de César, Oronge, or Kaiserling in German. Because this mushroom closely resembles the fly agaric, many people do believe that the Caesar's mushroom is actually the edible version of this poisonous mushroom.

This mushroom has a tawny cap with a yellow stem and gills. It may be seated in a cup-like volva (remnant of universal veil) and have the remains of a partial veil hanging from the stipe. The base of the stipe is thicker than the top. The spores are white. This mushroom favours oak woodland, sometimes mixed with conifers.

It has also been classified as A. umbonata. The relationship of the similar North American species A. hemibapha and A. jacksonii to A. caesarea is not clear. Moreover, the edibility of North American species is also unclear.
