What is St. George’s Mushroom?
St. George’s Mushroom, or Calocybe gambosa, is a prized edible mushroom that kicks off the foraging season in spring.
Its name comes from Greek: “calos” (pretty) and “cubos” (head) for its lovely cap, plus “gambosa” for its chunky stem base.
Around the world, it’s called Marzolino in Italy (March mushroom), Maipilz in Germany (May mushroom), or Vårmousseron in Denmark.
Known since the 1700s, it’s a favorite for its rich flavor and early appearance.
How to Identify St. George’s Mushroom
Spotting St. George’s Mushroom is straightforward if you know what to look for, but you’ve got to be careful, as some toxic mushrooms look similar. Here’s the rundown:
-
Cap: 5–15 cm wide, starting domed and flattening out. It’s smooth, sometimes cracking with age, and ranges from creamy white to light brown or yellowish.
-
Gills: Crowded, white to pale cream, slightly notched where they meet the stem.
-
Stem: 3–8 cm tall, thick, often bulbous at the base, and white to yellowish. No ring.
-
Spore Print: White to pinkish-white (place the cap on paper overnight to check).
-
Smell and Taste: Smells like wet flour or cucumber; tastes floury raw but turns savory when cooked.

Characteristics of St. George’s Mushroom
This mushroom has some standout traits. Its flesh is white, thick, and soft, perfect for cooking.
But watch out: older ones can attract maggots, so slice them open to check. It often grows in fairy rings, those cool circles in the grass that can be centuries old.
St. George’s Mushroom might team up with trees like hazel, beech, or oak, sharing nutrients in a mycorrhizal relationship.
Sometimes, it just feeds off dead grass.
When cooked, its floury raw taste transforms into a rich, mushroomy flavor.
In places like Spain’s Basque Country and medieval Italy, it’s been a culinary star for ages, even fetching high prices back in the day.
Where to Find St. George’s Mushroom: Habitat and Distribution
St. George’s Mushroom loves grassy spots and specific soils. Here’s where to look:
-
Favorite Spots: Pastures, lawns, roadsides, or under hedges and trees in woodlands.
-
Soil Preference: Chalky or lime-rich soils, though it can handle slightly acidic ones.
-
Growth Style: Often in fairy rings (darker, lusher grass circles) or scattered clumps.
-
Locations: Common across Europe (UK, Ireland, Germany, Italy, Scandinavia) and parts of North America.
When to Look

Cooler Regions (e.g., Germany, Scandinavia): May to July.
Foraging Tip: Once you find a patch, note the spot it’ll likely show up there next year. Avoid picking near busy roads, as mushrooms can soak up pollutants.
Cultural and Historical Significance
St. George’s Mushroom isn’t just food; it’s got cultural clout.
In medieval Italy, it was a luxury item, served at fancy banquets in places like Tuscany.
Today, it’s a big deal in Northern Spain, especially in the Basque Country, where it’s celebrated in spring festivals or sold at high prices in markets.
In the UK, its appearance signals the start of foraging season, bringing excitement to mushroom hunters.
Its fairy rings even inspired folklore about magical circles in the grass.
Foraging Safely: Tips for Beginners
Foraging is a blast, but safety comes first. Here’s how to do it right:
-
Pick Young Mushrooms: They’re tastier and less likely to have maggots. Cut lengthwise to check.
-
Gear Up: Use a knife for clean cuts and a basket to keep mushrooms fresh.
-
Use a Guide: Carry a field guide or app to confirm your find.
-
Test It: Do a spore print (white to pinkish-white for St. George’s) and sniff for that mealy smell.
-
Avoid Risky Areas: Skip spots near roads or polluted sites.
If you’re new, watch foraging videos online or join a local group. It’s the best way to learn the ropes and avoid mistakes.
