The Brown Fly Agaric, Amanita regalis, is not reported from Britain or Ireland, but it is quite common in Scandinavia. Apart from cap colour it is similar in size and form to the red Fly Agaric.

Like the Fly Agaric, this large member of the genus Amanita is also hallucinogenic and can cause sickness if eaten.

Similar species

Amanita caesarea (Caesar's Mushroom) is rarely if ever found in northern Europe; its cap is brilliant orange with a striated margin, and the stipe is yellow.

The caps of some examples of Amanita rubescens are glossy brown, but their stems and their cap flesh always turn red when damaged.
