While many people enjoy mushroom foraging, it can be a dangerous activity. There are many varieties of wild mushrooms that are toxic and highly dangerous if ingested, and some can even be harmful just through skin contact. Poisonous mushrooms can cause severe illness and even death, with symptoms including nausea, vomiting, abdominal pain, organ failure, and brain cell damage. It is therefore important to exercise caution when handling wild mushrooms and to avoid touching or consuming any mushrooms that have not been identified by an expert as safe.

What You'll Learn
Some wild mushrooms are toxic to touch
While some sources claim that poisonous mushrooms are safe to touch, other sources advise against touching wild mushrooms as many are highly toxic and can cause severe illness or death if ingested or even touched. Some mushrooms contain toxins that can enter the body through the skin. For example, a thin, red, finger-like mushroom found in Japan, Korea, and parts of Australia can transmit its toxins through skin contact. Similarly, the autumn skullcap mushroom, found in the Northern Hemisphere and Australia, can cause serious health issues such as peeling skin, hair loss, organ failure, and brain cell damage if touched or ingested.
The death cap mushroom, found worldwide, poses another serious threat as it can be easily mistaken for edible mushrooms. Its toxins can cause severe kidney damage and death, with just half a mushroom being enough to kill a person. Initial symptoms of touching this mushroom include flu-like symptoms, abdominal pain, vomiting, and bloody diarrhea, which can lead to rapid fluid loss, organ failure, coma, and death.
It is important to exercise extreme caution when encountering wild mushrooms, as it can be challenging to distinguish between edible and poisonous varieties. Cooking or processing poisonous mushrooms do not make them safe to consume, and even the fumes from cooking certain mushrooms can be toxic. Symptoms of mushroom poisoning can vary but often include nausea, vomiting, abdominal pain, and organ failure. In some cases, symptoms may not appear for several hours or even days after exposure, making timely treatment more difficult.
If you suspect that you or someone else has come into contact with a poisonous mushroom, it is crucial to seek medical advice immediately. Poison control centers and mushroom identification experts can provide guidance and help identify the specific mushroom in question to ensure prompt and appropriate treatment.

Symptoms of touching poisonous mushrooms
While touching poisonous mushrooms is not generally dangerous, some toxins can be absorbed through the skin. However, the amount of mushroom handling required to experience a fatal reaction would be massive, and there are no officially recorded instances of people poisoning themselves by handling poisonous mushrooms.
That being said, some mushrooms can cause skin irritation and allergic reactions when touched. For example, leukopenia and thrombocytopenia can make the skin look damaged (bruising and yellowing), and lamellar desquamation causes the skin to grow scales and peel off.
In rare cases, people may have allergic reactions to mushrooms, resulting in symptoms such as itchy skin or, in the most severe cases, anaphylaxis.
Additionally, it is important to note that touching poisonous mushrooms can be dangerous if you touch your mouth, eyes, or any other sensitive areas afterward, as this can lead to ingestion or eye irritation.
Therefore, while touching poisonous mushrooms is generally not harmful, it is always a good idea to exercise caution and avoid touching wild mushrooms unless you are certain they are safe.

How to identify poisonous wild mushrooms
While most mushrooms are not poisonous and some are edible, it is important to be able to identify poisonous wild mushrooms to avoid any mishaps. There is no simple way to tell if a wild mushroom is poisonous, and the consequences of misidentification can be life-threatening. Here are some ways to identify poisonous wild mushrooms:
- Get to know the wild mushrooms in your area before attempting to eat them. Learn everything you can about identifying safe-to-eat species.
- Look out for distinct features. For example, the fertile surface of Chanterelles has "folds" rather than gills, while the poisonous Jack O'Lantern mushroom has gills.
- Avoid all gilled mushrooms unless you can identify them with 100% certainty.
- Be extra cautious with wild mushrooms that resemble edible mushrooms. For example, the Death Cap mushroom, which is found worldwide, can be easily mistaken for edible mushrooms, but it contains a toxin that can cause severe kidney damage and even death. Similarly, the Deadly Webcap mushroom in Europe also looks like edible mushrooms, but its poison takes weeks to show symptoms that resemble the flu.
- Be aware of the potential danger of touching certain mushrooms. For instance, a thin, red, finger-like mushroom found in Japan, Korea, and parts of Australia can cause its toxins to enter the body through skin contact.
- Remember that all mushrooms will become toxic when they are very old and rotting.

Safe handling of wild mushrooms
While most sources agree that touching wild mushrooms is safe, some mushrooms can be toxic or poisonous and cause severe illness or death if ingested or even touched. Therefore, it is important to take precautions when handling wild mushrooms to ensure your safety. Here are some tips for safe handling of wild mushrooms:
Do not touch wild mushrooms with your bare hands: Use gloves or a thick piece of cloth to handle wild mushrooms. This will create a barrier between your skin and the mushroom, reducing the risk of any potential toxins being absorbed through your skin.
Be cautious of spores: Some mushrooms release spores, which can be inhaled and cause respiratory issues. Consider wearing a mask or covering your mouth and nose with a cloth to avoid inhaling spores when handling wild mushrooms.
Wash your hands thoroughly: After handling wild mushrooms, wash your hands with soap and water for at least 20 seconds. This will help remove any traces of the mushroom and prevent accidental ingestion or transfer to your eyes or nose.
Dispose of wild mushrooms properly: Do not leave wild mushrooms within the reach of children or pets. Place them in a sealed bag or container and dispose of them in a manner that prevents them from being consumed by animals or humans.
Educate yourself about mushroom identification: Learning about the different types of wild mushrooms and their characteristics can help you identify potentially dangerous species. However, always seek expert advice or confirmation before consuming any wild mushroom.
Seek medical attention immediately: If you experience any adverse effects after touching or consuming wild mushrooms, seek immediate medical attention. Call your local poison control center or emergency services, as prompt treatment is crucial in the event of poisoning.
Remember, while touching most wild mushrooms is likely safe, it is always better to be cautious. By following these guidelines, you can minimize the risks associated with handling wild mushrooms and ensure your safety.

What to do if you touch a wild mushroom
While most wild mushrooms are not dangerous to touch, some species, such as the thin, red, finger-like mushroom found in Japan, Korea, and parts of Australia, can be toxic and cause severe illness or death if ingested or touched. Therefore, it is essential to be cautious and take the necessary precautions when encountering wild mushrooms. Here's what you should do if you touch a wild mushroom:
- Identify the mushroom: Try to identify the mushroom by taking note of its physical characteristics, such as its shape, size, color, and any distinctive features. You can use field guides or online resources to help with identification. It is crucial to know that some poisonous mushrooms, like the death cap, can closely resemble edible mushrooms, so proper identification is essential.
- Wash your hands: If possible, wear gloves or use a barrier, like a tissue or leaves, when touching wild mushrooms.

This helps remove any potential toxins or spores that may be on your skin.
- Look out for symptoms: After touching a wild mushroom, pay attention to any physical reactions or symptoms that may occur. While it is rare for toxins to be absorbed through the skin in fatal doses, some mushrooms can cause skin irritation, rashes, or other allergic reactions. If you experience any discomfort or unusual symptoms, seek medical advice.
- Separate from edibles: If you are foraging for edible mushrooms, keep any unidentified or questionable mushrooms separate from those intended for consumption. Do not place wild mushrooms that you are unsure about into the same container or bag as your edibles. This minimizes the risk of accidental ingestion or contamination.
- Dispose of safely: If you encounter wild mushrooms, especially those suspected to be toxic, dispose of them safely. Do not leave them within the reach of children or pets. Place them in a sealed bag or container and dispose of them in a manner that prevents ingestion by people or animals.

Learn about the physical characteristics and habitats of toxic mushrooms to improve your ability to identify them accurately. This knowledge can help you make informed decisions when encountering wild mushrooms.
Remember, while touching most wild mushrooms is typically safe, it is crucial to prioritize caution and proper identification. Never consume wild mushrooms unless you are absolutely certain of their edibility. If you experience any adverse symptoms after touching or ingesting mushrooms, seek immediate medical attention and bring the mushroom with you, if possible, for accurate identification and treatment.
