Description of Caesar’s Mushroom.

Like other amanites, the good Caesar’s mushrooms, in the first stage of development, are wrapped by a membrane which is even 2 mm thick. The veil is fleshy and consistent and assumes the characteristic egg shape.

It is very important to underline this fact: only at this very early stage of development can the amanita caesarea can be confused with the deadly Amanita Phalloides, which also has a white egg shape.

The Cap

Once the mushroom begins to develop, the cap of the Amanita Caesaria begins to grow out of the white membrane that splits. It measures from 6 to 20 cm in diameter and at the beginning it has a hemispherical shape which then becomes flat and stretched out in the adult specimens.

The appearance is robust, smooth and brilliant. In wet weather, the cap looks viscous and not too rarely there are white fragments of the veil that stick to the cap and contrast with its bright orange.

The color is yellow orange or red orange with the typical warm shades. The colour of the cap of the
Amanita Caesaria mushrooms in question is sometimes variable and can range from orange with shades of red to more or less light yellow. The flesh under the cap is yellow.


The gills are thick and quite wide. Their colour is egg yellow and they are also intercalated by lamellulas.


The stem measures from 8 to 18 cm in height and is 2 to a maximum of 4 cm thick. Then, the shape is cylindrical and at the base there is an enlargement because the base is wrapped in the leathery vulva. The colour of the stem is always egg yellow with lighter shades in the upper part of the stem.


The membranous ring is present and is very showy in the upper part of the stem. The colour is the same of the stem and falls down like a festoon.


The flesh of the Amanita Caesarea is compact and tender in the hat. In the stem, on the other hand, the meat is more consistent. The colour is white and the taste and smell are very pleasant. This is until the fungus becomes mature, at that time it gives off a disgusting smell of rotten eggs.

Habitat and diffusion of Amanita Caesarea

The Caesar’s Mushroom prefers open areas with acidic soils such as chestnut and oak forests. In Italy it is widespread mainly in the centre and in the south, being a typically thermophilic species. In the north of Italy, however, there are some microclimates that are favourable to its development.

In general, being a symbiotic fungus, it coexists with the various broad-leaved trees (up to the exception of the Silvestre Pine). In order to grow, this fungus prefers the more open areas of the wood, for example those worked by woodcutters the previous year.

Period of Growth

The Amanita Caesarea grows from early summer until early October, usually. It is usually a species stormed by mushroom gatherers because of its delicacy, so finding it is not as easy as it may seem, even if the fungus is widespread. From here it can be deduced that the price of good harvested eggs can also be quite high.

As already said before, the amanita Caesarea can be confused with the Amanita muscaria which is poisonous. It can be also confused with the Russula aurata because it has a similar colour of the gills and of the cap. Also the Amanita crocea and the Amanita aureola are confusable with Caesar’s Mushroom.
