The fear of mushrooms, or mycophobia, is a recognised phobia. While it is not a universal phenomenon, it is prevalent in some cultures. People with mycophobia experience an intense fear of getting ill from a fungus, either by touching or eating poisonous mushrooms or breathing in mould spores. They may also experience physical symptoms such as shortness of breath, dizziness, or a smothering sensation. Some people with mycophobia only fear wild or unknown mushrooms, while others fear all types of fungi, including mushrooms, toadstools, and mould. The exact causes of mycophobia are unknown, but it may be influenced by cultural and historical factors, such as the association of mushrooms with toxicity and a lack of reliable information about their safety.

Fear of mushrooms may stem from industrialization
Mycophobia, or the fear of mushrooms, remains prevalent in some cultures despite the growing interest in fungi. While the exact causes of mycophobia are unknown, it is speculated that the phobia may be a product of industrialization.
During industrialization, there was a mass movement of people from rural areas to cities, which led to a disconnect from the land and a loss of oral knowledge about mushrooms. Ecologist and author Dr. Andy Letcher supports this theory, stating that mycophobia is not a European trait, as some of the largest markets for foraged mushrooms are in European countries such as Italy, France, Spain, and Switzerland. These cultures also invest in educating their public about the values and potential dangers of fungi.
In contrast, industrialization may have contributed to the spread of misinformation about mushrooms. With limited reliable information, people turned to classical scholars for advice, leading to conflicting messages about the edibility of mushrooms. For example, Pliny stated that all red mushrooms could be eaten, while Nicander claimed that only those growing on fig trees were safe. Dioscorides, on the other hand, suggested that all mushrooms were edible unless they grew above rusty iron or near a serpent's den. This lack of consistent information may have contributed to the fear and uncertainty surrounding mushrooms.
Additionally, industrialization could have intensified the fear of mushrooms by reducing people's exposure to them. In pre-industrial societies, people were more connected to the land and had a deeper understanding of their environment, including the identification and uses of mushrooms. However, as people moved to cities and became disconnected from nature, their knowledge and comfort level with mushrooms may have diminished.
Furthermore, the industrialization of food production and the rise of cultivated foods may have also played a role in shaping attitudes towards mushrooms. People became increasingly reliant on store-bought foods rather than foraging for wild foods, which could have contributed to a general wariness of wild mushrooms. Additionally, the development of modern medicine and the understanding of poison may have heightened fears of toxic mushrooms and their potential deadly consequences.

Some people fear mushrooms due to their appearance
The appearance of mushrooms can evoke feelings of disgust and anxiety in some individuals. For example, one person mentioned that seeing clusters of mushrooms makes them feel "itchy, dirty, uncomfortable, and anxious". The shape and colour of mushrooms can also play a role in people's fear of them. For instance, a yellow or white gill colour is often associated with poisonous mushrooms, as taught by parents to their children. This knowledge can contribute to a fear of mushrooms, as people may associate certain colours or shapes with toxicity and potential danger.
In addition to the physical appearance of mushrooms, some people's fears may be influenced by their portrayal in popular culture. For example, the video game character Parasect, where a mushroom kills a crab and controls its body, has been mentioned as a contributing factor to mushroom fears. Additionally, fictional works such as the hit show "The Last of Us" can also contribute to the perception of mushrooms as frightening.
It is worth noting that mycophobia is not limited to the fear of wild mushrooms. Some people may be comfortable eating common store-bought mushrooms like button and cremini mushrooms, while still fearing unknown or wild mushrooms. This fear can lead to avoidance behaviours, such as refusing to go to restaurants or stores that cook or serve mushrooms.
While the exact causes of mycophobia are unknown, it is believed that cultural and societal factors play a significant role. In some cultures, there is a lack of knowledge and education about the values and risks associated with mushrooms, leading to a general fear and avoidance of them. Additionally, the historical taboo surrounding magic mushrooms in ancient societies, where only priests were allowed to use them, may have contributed to the development of mycophobia.

Others fear mushrooms because of how they grow
The fear of mushrooms, or mycophobia, is a recognised phobia. While it is not a universal fear, it is prevalent in some cultures. For instance, mycophobia is common in the USA and the UK.
Some people fear mushrooms because of how they grow. One person expressed their fear of mushrooms in the following way:
> "I don't know how people can eat mushrooms. [...] They're so unnerving. [...] They just feel so sinister and alien to me for some reason, like they don't belong here."
Another person described their fear of mushrooms as follows:
> "Their mere appearance creeps me out immensely. It engages the amygdala for me like few things do. [...] I would never touch a mushroom let alone eat one. I would have to be restrained to do such a thing and would likely scream bloody murder."
The fear of mushrooms is also linked to the fear of poisoning. While it is true that some mushrooms are toxic or poisonous, only around 3% of known mushrooms are toxic. Nevertheless, some people experience anxiety at the idea of consuming mushrooms because of the risk of poisoning.
The fear of mushrooms may also be linked to the industrialisation and urbanisation of society. Ecologist and author Dr Andy Letcher suggests that British-based mycophobia may be a product of industrialisation, which caused people to move to cities and become disconnected from the land and their oral knowledge.

Some mushrooms are toxic, but only a handful cause poisonings
Mycophobia, or the fear of mushrooms, is prevalent in some cultures, despite the growing interest in fungi. This fear is not unfounded, as some mushrooms are toxic and can cause poisoning. However, out of the thousands of mushroom species, only about 100 are toxic, with a few of the 70-80 species of poisonous mushrooms being fatal when ingested.
Mushroom poisoning usually occurs when toxic mushrooms are misidentified as edible species due to their similar appearance. For example, the "destroying angels" are several species of all-white mushrooms that closely resemble edible button and meadow mushrooms. Another toxic mushroom is Amanita bisporigera, considered the most poisonous in North America. Other toxic mushrooms include Omphalotus spp., also known as "Jack-o-lantern mushrooms," which can cause significant toxicity, and Cortinarius orellanus, which has been linked to kidney failure.
To prevent mushroom poisoning, it is essential to familiarize yourself with both the edible mushrooms and their toxic counterparts. Additionally, the preparation methods for cooking wild mushrooms can impact their safety. While most mushroom poisonings result in gastrointestinal upset, certain species can cause more severe symptoms, such as nausea, vomiting, abdominal cramping, diarrhea, headaches, vertigo, palpitations, and even liver toxicity.
It is worth noting that the fear of mushrooms may be influenced by cultural and societal factors. For instance, industrialization and urbanization may have contributed to mycophobia by disconnecting people from their oral knowledge of mushrooms. Additionally, the portrayal of mushrooms in popular culture, such as in the show "The Last of Us," can shape perceptions and contribute to their frightening reputation.
While some mushrooms are indeed toxic, it is important to recognize that only a small proportion causes poisonings. Educating oneself about the different mushroom species and their potential dangers can help address unfounded fears and promote the safe enjoyment of these fungi.

People with mycophobia may avoid restaurants, grocery stores, or other people's houses
Mycophobia, or the fear of mushrooms, remains prevalent in some cultures. While it is a relatively small group of people who suffer from this phobia, their lives can be severely impacted. People with mycophobia may experience shortness of breath, dizziness, or a smothering sensation when faced with their fear. They may go to great lengths to avoid encountering mushrooms, including refusing to go to restaurants, grocery stores, or other people's houses. This is because they fear that they may come into contact with a mushroom, fungus, yeast, or mold in these places.
The fear often stems from a very real concern about the toxicity of certain mushrooms. Some people with mycophobia may be worried about accidentally consuming poisonous mushrooms or breathing in mold spores. This fear can be exacerbated by a lack of knowledge about the different types of mushrooms and their potential dangers.
In some cases, mycophobia may be linked to a more general fear of fungi and mold. This could be due to the way mushrooms grow, with some people finding it unnerving or sinister. Others may associate mushrooms with death or illness, as some varieties are known to be toxic and can cause serious health issues if consumed.
The cultural and historical context also plays a role in the prevalence of mycophobia in certain societies. In some cultures, mushrooms have been associated with taboo and restricted only to priests or scholars, creating a sense of fear and uncertainty among the general public. Additionally, industrialization and urbanization may have contributed to mycophobia by disconnecting people from the land and oral knowledge about mushrooms.
While the exact causes of mycophobia vary and are not yet fully understood, it is clear that this phobia can significantly impact the daily lives of those affected, potentially limiting their dining and socializing options.
