St. George's Mushroom
Calocybe gambosaGuide to St. George's mushroom in Italy: where Calocybe gambosa grows, spring season and habitat in meadows and pastures. How to identify it by its unmistakable smell.
St. George's mushroom — Calocybe gambosa — is the spring meadow mushroom par excellence. It appears between March and June in pastures, clearings, along forest edges and in fallow fields, often in rings or rows that mark habitual growth sites returning year after year. The floury-honeyed smell is very strong and characteristic: you can detect it from a distance. It is a saprotrophic fungus, not mycorrhizal, decomposing organic matter in grassy soil. In favourable years it is very abundant, especially in Tuscany, Umbria and the Piedmontese valleys. The season is short: you need to be quick.
Habitat
Meadows, pastures, clearings, path edges, fallow land and forest margins. Does not enter dense forest. Prefers soils rich in organic matter, moderately moist, from 100 to 1200 metres. Often forms rings or rows (fairy rings) at sites that repeat year after year.
How to identify st. george's mushroom
- Strongly floury-honeyed smell — immediate distinguishing character
- White or cream cap, convex then flattened, inrolled margin when young
- Dense white sinuate gills
- Stout, white, short stem
- Growth in meadows/pastures, never in dense forest; often in rings or rows
Similar species — pay attention
Clitocybe dealbata and C. rivulosa: toxic, grow in meadows, white gills, but sweetish-nauseating smell (not floury). Entoloma sinuatum: toxic, pink gills when adult, different smell. The decisive character is the smell: St. George's mushroom smells unmistakably of flour and honey.
