Calocybe gambosa, commonly known as St. George's mushroom, is an edible

sautéed
with egg or with bacon.

It is considered a delicacy, especially when fried in butter. It was previously considered a part of the large genus Tricholoma and is still seen as T. gambosum in older texts.

Taxonomy

Initially described as Agaricus gambosus by Elias Magnus Fries in his 1821 work Systema Mycologicum,[2] with its specific epithet derived from a Latin term for "club footed" in relation to its bulky stipe.[1] It was later named Tricholoma gambosum by Paul Kummer in 1871,[3] before being reclassified as Calocybe gambosa by Marinus Anton Donk in 1962.[4] In Germany it is known as Maipilz, where it fruits in May.[5] The genus name is derived from the Ancient Greek terms kalos "pretty", and cubos "head".[6] In Denmark it is called Vårmousseron, appearing in spring—early May [7]

Description

The cap measures from 5–15 cm (2 to 6 inches) in diameter and has a smooth texture and has ridges on it. The colour of the cap, stipe and flesh can range from white-creamy coloured to bright yellow. The sinuate gills are white and crowded. The flesh is thick and soft and has a mealy or cucumber smell. The spore print is white to pinkish white. The stubby stipe is bulky at the base.[1]

Care must be taken not to confuse it with the highly poisonous Inosperma erubescens, which grows in the same habitats. The latter has a more pungent fruity smell and bruises red. Entoloma sinuatum, also poisonous, has a rancid smell.[5]

Distribution and habitat

Calocybe gambosa is common in grasslands in

Baltic sea. On the South Downs in southern England, it has formed huge fairy rings that appear to be several hundred years old.[8] It is found from April in the United Kingdom, and earlier in warmer countries.[1]

Edibility

The mushroom is best picked in dry weather. It can be eaten dry, pickled or even raw. It is imported in commercial quantities into Western Europe from Romania.[1] It was held in high esteem in medieval Italy, reported by Costanzo Felici in 1569 as the most expensive and highly regarded mushroom in Umbria and Marches in central Italy, and held in high esteem in the Apennine mountain region—Liguria, Tuscany, and Emilia-Romagna)—by Giovanni Targioni Tozzetti in 1777. It is still locally eaten in Emilia-Romagna and Tuscany.[9]

St George's mushroom is highly prized in the

snails.[11] The mushroom is also a cornerstone of the gastronomy of Bilbao, where it is typically eaten in an omelette.[12] The demand in the Basque Country is so high the mushroom has to be imported from Eastern Europe.[citation needed

Calocybe gambosa grows at the same time of year and locations to, and can be confused with, young

Inocybe erubescens (poisonous), Melanoleuca strictipes (inedible), and Entoloma sinuatum (poisonous).[13]
