Latin Name

Amanita muscaria


Native to temperate regions of the Northern Hemisphere, the fly agaric can be found across Europe, Asia, and North America.


The most notable features of the fly agaric are its bright red or orange cap adorned with white warts. It also has a white stem, gills, and a skirt-like ring.


The cap can range from 8 to 20 cm in diameter, and the stem can be between 8 to 25 cm tall.


These mushrooms prefer birch, pine, and spruce forests but can also be found in grassy areas near these trees.


Fly agaric is mycorrhizal, forming symbiotic relationships with trees by exchanging nutrients.


Like other fungi, they begin as spores that grow into mycelium, an underground network. When conditions are right, the mycelium produces the fruiting bodies (mushrooms) above ground, which will eventually release spores and start the cycle again.

Defense Mechanisms

The fly agaric contains psychoactive compounds, including muscimol, which can cause hallucinations, confusion, and other symptoms if ingested. This serves as a natural defense mechanism against consumption. The name “fly agaric” comes from its traditional use in some places as a fly killer, where pieces of the mushroom are placed in milk to attract and kill flies.

Ecological Importance

Beyond their role in nutrient cycling within the ecosystems they inhabit, fly agarics also form important mycorrhizal partnerships with certain trees, helping them absorb nutrients.

Conservation Status

They are common and not considered threatened.
