St George's Mushroom, Calocybe gambosa


Calocybe gambosa, commonly known as the St. George's mushroom, is a very tasty edible fungi that froms rings in fields and on grass verges and roadsides during the spring months. It's common name unfortunately has nothing at all to do with dragons, but is related to when it first appears in the UK - on or around St George's Day in April! A quite large, white or off-white mushroom, the St George's is easy to ID thanks to it's pungent wet flower smell and the fact that it fruits very early in year, meaning it is extremely unlikely that it can be confused with anything else.
