Fly agaric description
| Kingdom | Fungi |
| Phylum | Basidiomycota |
| Class | Basidiomycetes |
| Order | Agaricales |
| Family | Amanitaceae |
| Genus | Agaricus (1) |
The fly agaric is an attractive, vibrantly coloured toadstool, which is familiar and instantly recognisable (3). It has a bright red cap, which fades to an orange or orange-yellowish colour with age. The fluffy white spots on the cap often take on a yellowish tinge as they grow old, and may occasionally be washed away by rain (4). The stem has a bulbous base, and tapers towards the cap (3). This fungus is dangerously poisonous and should NEVER be tasted (2). The name fly agaric derives from the fact that since medieval times it was commonly used as a fly killer, broken up in milk or sprinkled with sugar (3).
WARNING: Many species of fungus are poisonous or contain chemicals that can cause sickness. Never pick and eat any species of fungus that you cannot positively recognise or are unsure about. Some species are deadly poisonous and can cause death within a few hours if swallowed.
TopFly agaric biology
Fungi are neither plants nor animals but belong to their own kingdom. They are unable to produce their own food through the process of photosynthesis, as plants do; instead, they acquire nutrients from living or dead plants, animals, or other fungi, as animals do. In many larger fungi (lichens excepted) the only visible parts are the fruit bodies, which arise from a largely unseen network of threads called 'hyphae'. These hyphae permeate the fungus's food source, which may be soil, leaf litter, rotten wood, dung, and so on, depending on the species (4).
The fly agaric is found from August to November in Europe, and from June to October in North America (3). It grows solitarily or in scattered groups (2). Fly agaric is eaten by reindeers, and is associated with Christmas in many parts of Europe. It has even been suggested that the use of fly agaric in midwinter festivals in Siberia may have been the inspiration for some of the features of Santa Clause, including his red and white robes, use of chimneys and his association with flying reindeer (5).
TopFly agaric range
This widespread toadstool occurs in Europe and North America. It was introduced to Australia, South Africa and New Zealand with pine trees imported from Europe (3).
TopFly agaric habitat
Grows under birch and spruce trees on acidic soils (4).
TopFly agaric status
A common, widespread species (3).
TopFly agaric threats
This fungus is not threatened.
TopFly agaric conservation

Glossary
- Fruit body
- In fungi, the fruit body is the visible part of the fungus which bears spores (microscopic particles involved in both dispersal and reproduction).
- Photosynthesis
- Metabolic process characteristic of plants in which carbon dioxide is broken down, using energy from sunlight absorbed by the green pigment chlorophyll. Organic compounds are made and oxygen is given off as a by-product.
