Australia is home to over 250,000 species of fungi, but only around 5,000 have been described, and only a small portion of those have been assessed as safely edible. Mushroom foraging has become increasingly popular in Australia, but it can be dangerous, and even experienced foragers can make mistakes. It is therefore important to have a good understanding of the basic anatomy of fungi and to use reputable reference texts and field guides to help identify different species. Some of the toxic mushrooms found in Australia include the yellow stainer, the green-spored parasol, and the death cap mushroom, which can cause liver failure or death. Australia also has native magic mushrooms, which produce the psychoactive compound psilocybin, and are the subject of ongoing research and clinical trials.

What You'll Learn
Where to find edible mushrooms
Australia is home to over 250,000 species of fungi, but only around 5,000 have been described, and only a tiny fraction of those have been assessed as safely edible. Mushroom foraging can be dangerous, and even experienced foragers can make mistakes. It is therefore important to treat any mushroom you find as toxic until proven otherwise.
If you are foraging for edible mushrooms, it is important to have a good understanding of the basic anatomy of fungi. Reputable guidebooks will use terminology such as pores, gills, and teeth to describe different types of mushrooms, so it is vital to know the difference. There are a handful of edible mushrooms that have no close toxic lookalikes, including Saffron Milkcaps, Weeping Boletes, and Slippery Jacks. However, many other edible mushrooms have doppelgangers that can cause serious harm if ingested.
To identify mushrooms confidently, it is recommended to use Australian texts as a starting point, and then look up the identified species in texts and reference websites from around the world. Many of the edible species in Australia originally came from Europe, so there is a wealth of informative material available from outside of Australia. It is also important to make sure you are foraging in a safe, legal area, and to bring a sharp knife and a small brush to cut and clean any mushrooms you find.
There are several guidebooks available to help identify mushrooms in Australia, including "Wild mushrooming: a guide for foragers" by Alison Pouliot and Tom May, which has been praised for its user-friendly layout and useful content for beginner foragers. Another option is "Rainforests of Australia's East Coast", which features over 800 colour photographs, informative graphics, maps, and detailed descriptions of more than 300 species. However, it is important to note that mushroom identification apps do not appear to be accurate enough in Australia, and even identification books may not be reliable for distinguishing edible from toxic mushrooms.
In addition to guidebooks and websites, it is possible to learn about mushroom identification by participating in foraging tours and identification groups. These can provide hands-on experience and guidance from experts, which can be invaluable for learning how to confidently identify different species of mushrooms.

How to identify mushrooms
Australia is home to over 250,000 species of fungi, but only around 5,000 have been described, and only a small portion of those have been assessed as safely edible. Therefore, it is important to treat any mushroom you find as toxic until proven otherwise.
To identify mushrooms, it is imperative to first learn the basic anatomy of fungi, such as the difference between pores, gills, and teeth. You can then refer to reputable reference texts, field guides, and websites to help you identify different species. Some recommended resources include "Wild mushrooming: a guide for foragers" by Alison Pouliot and Tom May, and "Rainforests of Australia's East Coast", which contains over 800 colour photographs, maps, and descriptions of over 300 species. It is also useful to know that many of the edible species in Australia originally came from Europe, so you can refer to European texts and websites for more information.
When foraging for mushrooms, always make sure you are in a safe and legal zone. Bring a sharp knife and a small brush to cut and clean the mushrooms, and guidebooks to help identify specimens. Remember to leave any mushrooms you are unsure about. Mushroom identification apps do not appear to be accurate enough in Australia, and it is unclear how useful mushroom identification books are at helping people distinguish between edible and toxic mushrooms.
Some edible mushrooms that have no close toxic lookalikes include Saffron Milkcaps, Weeping Boletes, and Slippery Jacks. However, toxic mushrooms can resemble edible ones and may look different depending on where they grow, including across continents. Some toxic mushrooms found in Australia include the yellow stainer, Agaricus xanthodermus, the green-spored parasol, Chlorophyllum molybdites, Amanita muscaria, and the death cap mushroom, Amanita phalloides.

Toxic and poisonous mushrooms to avoid
Mushroom foraging has become increasingly popular in Australia in recent years. However, it can be dangerous, as many toxic mushrooms resemble edible ones and can have severe, sometimes fatal, health consequences. It is advised to consider any mushroom found in the wild as toxic until proven otherwise.
There are several poisonous mushrooms that are known to cause poisonings in Australia. The most common cause of poisonings due to ingestion in Australia is the Agaricus xanthodermus, or Yellow-staining mushroom. This mushroom is found in many parts of Australia and causes symptoms such as stomach pain, nausea, vomiting, and diarrhoea. It can be identified by its chemical-like smell and the fact that its cap and stem stain yellow when damaged.
Another very dangerous mushroom is the Death Cap (Amanita phalloides), which has led to several fatalities in Melbourne and Canberra. Consuming just one Death Cap mushroom can kill an adult. Symptoms include stomach pains, nausea, vomiting, and diarrhoea, followed by a false sense of recovery, and then serious harm, particularly to the liver.
Other toxic mushrooms to avoid in Australia include Omphalotus nidiformis (Ghost Fungus), Chlorophyllum brunneum (Shaggy Parasol), and species of Scleroderma (Earthball). Some species of Galerina also bear a striking similarity to Psilocybe (Golden Tops) and occur in similar habitats, increasing the possibility of a fatal psychotropic feast.
If you suspect that you or anyone in your care may have eaten a poisonous mushroom, do not wait for symptoms to occur. Call the Victorian Poisons Information Centre immediately on 13 11 26 for appropriate advice. Keep a sample and a photograph of the mushroom that was consumed to aid in identification.

Magic mushrooms and their effects
Magic mushrooms, or mushrooms that contain psilocybin, have a variety of effects on individuals. The effects of magic mushrooms usually begin within 15-45 minutes when eaten, or within 5–10 minutes when taken as a soup or tea, and can last approximately four to six hours. The key ingredient in magic mushrooms is psilocybin, which is converted in the body to psilocin, the chemical with psychoactive properties. Psilocybin is a hallucinogenic substance, and its consumption can lead to hallucinations, perceptual changes, and an altered state of consciousness. It may also distort how some people perceive objects and people in their environment, resulting in a distorted sense of reality.
The effects of magic mushrooms vary from person to person. Some individuals may experience euphoria, heightened emotions and senses, and a sense of mental and emotional clarity. They may laugh or giggle a lot, and even experience feelings of happiness and creativity. On the other hand, some people may experience disturbing hallucinations, anxiety, agitation, paranoia, loss of boundaries, and a distorted sense of self. Feelings of stress or anxiety before using magic mushrooms may result in a "bad trip". During a bad trip, individuals may experience frightening episodes, and impaired judgment, which may lead to risk-taking behavior and, in some cases, even death.
Magic mushrooms have a low risk of addiction, and there are not many known withdrawal effects. However, regular users may experience flashbacks involving previous magic mushroom experiences. It is important to note that magic mushrooms should not be taken by people on psychiatric medications as it may cause a relapse or worsening of the condition. Additionally, some magic mushrooms may resemble poisonous mushrooms, which can cause severe sickness and even death.

Field guides and books on mushroom identification
Mushroom foraging has become increasingly popular in Australia, but it can be a risky activity. It is estimated that Australia is home to over 250,000 species of fungi, but only around 5,000 have been described, and only a small portion of those have been assessed as safely edible. Mushroom identification apps have been found to be inaccurate in Australia, and books on the topic may not be much more helpful. However, there are some field guides and books that can help foragers learn to identify different species of mushrooms.
One such guide is "Wild mushrooming: a guide for foragers" by Alison Pouliot and Tom May. This guide has been described as having the most user-friendly layout and the most useful content for beginning foragers of any Australian fungi field guide. It is an invaluable resource to keep on hand while foraging.
Another option is "Rainforests of Australia's East Coast", a practical and informative field guide to the identification of native rainforest species, including mushrooms. The book features over 800 colour photographs, informative graphics, maps, and detailed descriptions of more than 300 species.
In addition to these Australian texts, it can be helpful to refer to texts and websites from around the world, as many of the edible species found in Australia originally came from Europe, and there is a wealth of information available based on centuries of foraging traditions.
It is important to remember that even experienced foragers can make mistakes, and some mushrooms found in Australia can be extremely dangerous or even deadly. It is always best to assume that any mushroom you find is toxic until you can undeniably prove otherwise. If you think you have eaten a toxic mushroom, contact a poisons information centre as soon as possible.
