The classic fairy tale toadstool, this red and white fungus is often found beneath birch trees in autumn. Species information Category Fungi. Statistics Cap diameter: cm Stem height: cm.
Conservation status Common. When to see August to November. About Fly agaric is probably our most recognisable species of fungus, with the mushroom's distinctive red cap and white stalk featuring in countless stories, television shows and even video games!
Fly agaric is found in woodlands, parks and heaths with scattered trees, typically growing beneath birch trees or pines and spruces. The colourful fruiting bodies can usually be seen between late summer and early winter. Like most fungi, the parts we see are just the fruiting bodies, or mushrooms. His research centred on the alkaloids extracted from plants and animals.
In he received a PhD for his structural work on chitin. However, it was his research into the alkaloids extracted from a fungus that eventually led to his unintentional fame. In the years up to , Hofmann systematically investigated lysergic acid derivatives, but many showed little medicinal activity and so he moved on to other more promising compounds.
Four years later on 16 April , Hofmann returned to lysergic acid diethylamide LSD and accidentally absorbed a small dose of this compound through his skin, becoming the first person to experience its effects.
Three days later, he intentionally ingested g of LSD, leading to what has become known as his 'bicycle day' as he experienced a psychedelic bicycle ride on his way home from work.

Fruiting begins with the fungal hyphae coming together to form an egg-shaped structure that breaks through the soil surface as it grows and expands.
The young, red fruiting body is covered in a universal veil that is white and splits apart as the stem grows up and the cap opens out. As the fruiting body matures, the cap becomes flat, sometimes with a slight depression in the centre, and grows up to 20 cm.
On the underside of the cap, the closely packed gills are white and free, meaning that they are not connected to the stem. The cap is borne on a white stipe, or stem, which can be from 5—20 cm. The stem will often have a white, flaccid ring around it, just below the cap.
At the base of the stem is a swollen or bulbous section known as the volva, and this is the remains of the universal veil, the membraneous structure that covered the young fruit body when it was emerging from the soil.
The spots on the cap are also remnants of the veil, although they can disappear over time as the cap expands and opens out. Large quantities of white spores are released from the gills, and these are oval in shape and microscopic in size.
They are dispersed by the wind over large distances, but only a few will germinate and grow successfully to become new fungi. Fly agaric mushrooms can appear either singly or in small clusters, and in the latter they can be at different stages of their development, even though they are growing right next to each other. Individual fruiting bodies usually persist for 1 — 3 weeks, with the cap often turning a paler red or even yellow colour as it ages, before the whole mushroom very quickly rots and decomposes.
The fly agaric is poisonous, but ingestion of it is very rarely fatal. Its common name is derived from the fact that it is in the fungal taxonomic order Agaricales and historically it was used for killing flies by placing dry powdered material from its mushrooms in milk.
In Scotland the fly agaric is usually seen fruiting in close proximity to birch trees, and this is because it has an ectomycorrhizal relationship with them. In this symbiotic , mutually-beneficial relationship, the hyphae of the fungus wrap around the root hairs of a tree.
