Description

Macrolepiota procera (parasol mushroom) is one of the largest gilled mushrooms in Europe. When fully opened, it resembles a parasol — hence the name. Highly prized for the delicate flesh of its cap. In Portugal it is known as “púcara”, “roca” and “frade” (monk — after the shape of the unopened fruiting body).

Cap

• Diameter: 10–40 cm (one of the largest mushrooms!)
• Shape: egg-shaped when young, later parasol-shaped with a central umbo
• Colour: beige, light brown with large brown scales
• Centre: darker, smooth
• Margin: thin, sometimes overhanging

Stem

• Height: 15–40 cm
• Width: 1–2.5 cm
• Colour: brownish
• Surface: covered with a snakeskin pattern (dark brown scales on a light background) — key identifying feature
• Ring: large, double, freely movable up and down the stem — the most important diagnostic feature
• Base: bulbous

Flesh

• Colour: white, does not change colour when cut
• Smell: pleasant, nutty
• Taste: mild, pleasant
• Feature: cap flesh is soft and tender; stem flesh is tough, fibrous — the stem is not eaten

Gills

• Colour: white, becoming cream with age
• Attachment: free (not attached to the stem)
• Spacing: crowded

Look-alikes

Safety rule

Three signs of the true parasol mushroom:

1. Large size — cap over 15 cm
2. Movable ring — slides freely up and down the stem
3. Snakeskin pattern — dark scales on the stem forming a “snakeskin”

If any of these signs is absent — do not collect the mushroom.

Culinary use

The parasol mushroom is a delicacy highly prized in European cuisine.

Preparation methods

• “Schnitzel” — the classic method: dip the cap in egg and breadcrumbs, then fry. The most popular recipe
• Pan-frying — sliced caps with garlic and herbs
• Grilling — whole caps on the grill with olive oil
• Drying — dries well, aroma intensifies

Notes

• Only caps are used — stems are too fibrous
• Best to collect young specimens while the cap is still not fully opened
• Can be eaten raw in salads (one of the few mushrooms suitable for this)
