The Amanita caesarea mushroom gets its name from its use as a favorite snack of early Roman emperors. First recorded over 2,000 years ago during the Roman empire, these mushrooms were held in such high esteem that they were even depicted on Roman frescoes and mosaics.

However, human cultivation has now spread them to other parts of Europe, as well as western Asia and the Middle East. Their association with oak trees remains an important factor in their life cycle even when commercially grown.

While loved by Roman rulers, Caesar’s mushroom fell out of prominence with the decline of the Roman empire. They remained largely forgotten through medieval times and were only rediscovered as a unique wild edible in the 18th and 19th centuries. 

It wasn’t until the late 1900s that the Amanita caesarea mushroom truly regained its status as a choice edible mushroom. Its complex earthy flavors were a hit with gourmet chefs and discerning foodies. Today, it remains highly sought after in culinary circles, commanding premium prices for its short seasonal availability.
