Caesar's mushroom (Amanita caesarea): where and when it grows
The queen. Orange as a golden egg, scarce and ever more sought after.
The caesar's mushroom (Amanita caesarea) comes out from August to October, at its best in September, in woods of holm oak, cork oak, Pyrenean oak, sweet chestnut, downy oak, Portuguese oak, sessile oak and pedunculate oak, from low ground up to the middle mountains. It is also known as Caesar's amanita.
See where it is ready this week
Right now, the best day forecast for Caesar's mushrooms is 26 October.
Caesar's mushroom is the most coveted mushroom of the holm oak and chestnut woods on the acid soils of western and central Spain. It comes up with the first heavy rains of late summer, while the ground is still warm, and disappears as soon as the cold bites.
It is rare, which is why the people who know where it grows keep quiet. micomapa will not tell you the spot, but it will tell you the week: when the August or September rain has fallen on still-warm soil in a wood of holm oaks, cork oaks or chestnuts.
What it needs to come out
First, a generous rain, the kind that soaks down to the roots. Then patience: it usually appears after two or three weeks, as long as the soil holds on to that moisture and stays warm, with the summer heat still in it. If a frost, too much water or a drying wind comes in between, the flush is aborted and never shows.
Where to look
It comes out in woods of holm oak, cork oak, Pyrenean oak, sweet chestnut, downy oak, Portuguese oak, sessile oak and pedunculate oak, from low ground up to the middle mountains, always on acid soils.

Mushrooms that share its woods
- Bronze bolete: The bolete of the holm oak woods: dark, stout and firm-fleshed. The most prized of its family.
- Sweet chestnut: Autumn's fruit in the groves of the north and the mountains of the south. It falls on its own, and every valley has its week.
- Wild asparagus: The first green of the year. It comes up after rain, in the scrub and along field margins, and lasts as long as spring does.
- Gurumelo: The mushroom of the south-western spring. It breaks out of the ground like a white stone and smells of wet earth.
- Chanterelle: Yellow, fragrant and loyal: once it finds its corner, it comes back every year.
- Black trumpet: Black, invisible in the leaf litter and delicious. Those who can see it would not swap it for anything.
