the fairytale mushroom that is genuinely toxic
- Size
- Cap: 8–20 cm, Stem: 8–15 cm
- Lifespan
- 1–2 years
- Diet
- Mycorrhizal: forms symbiotic relationship with roots of introduced and native trees, particularly birch, pine and beech. Exchanges nutrients and water with tree.
- Habitat
- Grows under introduced and native trees. Forms large mushrooms with bright red to orange-red cap covered with white fluffy patches, skirt-like ring and bulbous base.
- Range
- Throughout North and South Islands under introduced birch, pine and native beech trees. Most common in pine plantations and beech forests of the South Island.
- Endemism
- Introduced
- Main Threats
- None. This introduced species is naturalised and widespread. It is a public health hazard due to toxicity, but not a conservation concern.
- Population
- The classic fairy tale toadstool with bright red cap covered in white spots. Found under introduced birch and pine, and also under native beech. Toxic, causing hallucinations, nausea and disorientation.
- Conservation Status
- Introduced
It looks like it belongs in a children's book. The Fly Agaric is the fairy tale mushroom, defined by a colour that demands attention. The cap spans eight to twenty centimetres across. It is bright red to orange-red. White, fluffy patches cover the surface. They look like warts or snow. Beneath the cap, the gills are white to cream. They are crowded and free from the stem. The stem rises eight to fifteen centimetres tall. It is white. A large, skirt-like ring clings near the top. The base is bulbous. It is a mushroom that is instantly recognisable.
This is the toadstool where fairies sit. It is the umbrella for gnomes. It appears on Christmas cards and in folklore. But the Fly Agaric is not as innocent as it looks. It is toxic. It contains the psychoactive compounds muscimol and ibotenic acid. Eating it causes hallucinations. It brings nausea, dizziness, and disorientation. It is not usually fatal. But it is not a pleasant experience. It is a mushroom that is both beautiful and dangerous. The allure is deceptive.
Biologically, it is a mycorrhizal fungus. It forms a partnership with the roots of trees. In New Zealand, the Fly Agaric has found a new home. It grows under introduced birch and pine trees. It also grows under native beech. It is an introduced species that has naturalised. It spreads through forests and parks. It does not discriminate between native and exotic hosts. It takes what is available.
The Fly Agaric has a long history of use. It served as a sacrament in Siberian and European shamanic rituals. The hallucinations it produces were interpreted as spiritual visions. They were seen as a way of communicating with the spirit world. The chemical effect was mistaken for divine presence. The tradition persists in some circles. The risk remains high.
To find a Fly Agaric is to find a piece of European folklore growing in a New Zealand forest. The pine plantation is quiet. The mushroom grows under the trees. Its bright red cap with white spots looks like a fairy tale. It does not know it is toxic. It does not know it is a sacrament. It simply exists in the damp soil. It trades nutrients with a pine tree. That is its entire purpose. The forest is never static. It is always changing. The Fly Agaric is proof of this shift. It carries on.
No one told it otherwise.
