Mushrooms are a staple in vegetarian and vegan diets due to their umami flavour and nutrient density. However, they are not plants. They are a fungus, categorised in the Fungi kingdom, distinct from the Plantae kingdom where plants are categorised. Mushrooms lack a central nervous system and cannot feel pain. They are also able to be grown organically and without the use of animal products. Despite this, some controversy arises with certain types of mushrooms, such as oyster mushrooms, which attract and feed on nitrogen-rich prey, including small roundworms.

What You'll Learn
Mushrooms are fungi, not plants
Mushrooms are not plants; they are fungi. They are part of the Fungi kingdom, which is distinct from the Plantae kingdom (plants) and the Animalia kingdom (animals). The genetic composition of mushrooms is, in fact, more similar to humans than to plants. For example, mushrooms exposed to sunlight produce vitamin D, much like humans. They also store reserve energy as glycogen, whereas plants store it as starch.
The cell walls of mushrooms are made of chitin, a substance found in the shells of insects, crabs, and other arthropods. In contrast, plant cell walls are made of cellulose. Mushrooms also lack a central nervous system, and there is no evidence that they can feel pain like animals. They are about as conscious as plants.
When considering whether mushrooms are vegan, it is important to note that they are not animals. Some mushrooms get their nutrients from plant-based sources, while other types of fungi may grow on decaying animals or manure. However, most mushrooms that humans consume are farmed and grown on plant matter, ensuring they do not contain any animal products.
Oyster mushrooms, for example, grow on dead tree trunks and have limited access to nitrogen. To supplement their diet, they attract and consume nitrogen-rich prey, including small roundworms. This has sparked controversy about whether oyster mushrooms are truly vegan. However, it is challenging to determine whether the vegetables we eat are grown in soil free of decomposing animal matter.
Overall, mushrooms are fungi, not plants, and their consumption is generally considered vegan-friendly due to the absence of a central nervous system and the potential for ethical cultivation.

They are vegan-friendly
Mushrooms are vegan-friendly. While they are not plants, they are also not animals. They are classified as fungi, which is a separate kingdom from plants and animals. This means that, while mushrooms are not plant-based, they are vegan-friendly because they do not come from animals.
Mushrooms have a distinct umami flavour that many liken to chicken, seafood, or meat. They are also versatile and can be prepared in a variety of ways, making them a popular meat substitute for vegans and non-vegans alike. They are nutrient-dense and offer many of the health benefits of plants, such as vitamins B and D, which are important for building strong bones, reducing inflammation, and improving immune function.
The fact that mushrooms lack a central nervous system and are therefore unable to feel pain or distress in the same way that animals do further supports their classification as vegan-friendly. They are also capable of being grown 100% organically and ethically, without the use of any animal products.
However, it is important to note that there is some controversy surrounding certain types of mushrooms, such as oyster mushrooms. Oyster mushrooms grow on the trunks of dead trees, where they have limited access to nitrogen. To supplement their diet, they attract and consume nitrogen-rich prey, including small roundworms. Because of their role as predators of small organisms, some people argue that oyster mushrooms should not be considered vegan.
Despite this controversy, the prevailing sentiment is that mushrooms, including oyster mushrooms, are vegan-friendly. They have been a staple in many vegetarian and vegan diets and are widely used as a meat substitute.

They are grown without animal products
Mushrooms are not plants. They are fungi, and their genetic composition is more similar to humans than to plants. Mushrooms produce vitamin D when exposed to sunlight, just like humans, and they store reserve energy as glycogen, whereas plants store energy as starch. Mushrooms are part of the Fungi kingdom, which is distinct from the Plantae kingdom (plants) and the Animalia kingdom (animals).
Mushrooms are commonly consumed as part of a vegan diet, as they are not animals. However, some people question whether mushrooms are truly vegan because they are decomposers, getting their food from decomposing organic matter. Certain types of mushrooms, such as oyster mushrooms, are more controversial because they attract and consume nitrogen-rich prey, including small roundworms, to supplement their diet.
Despite these concerns, mushrooms can be grown without the use of animal products. When farmed by humans, their growing medium can be controlled to ensure it does not contain any animal by-products. Popular edible mushrooms, such as oyster mushrooms and shiitake mushrooms, thrive on wood-based substrates. By purchasing mushrooms from local farmer's markets or directly from growers, individuals can confirm that the mushrooms were grown without manure or other animal by-products.
In addition to being ethically sourced, mushrooms offer several nutritional benefits. They are a good source of vitamins B and D, which are typically found in animal products, and they provide a meaty taste and texture that is difficult to replicate with vegetables. Dried shiitake mushrooms, in particular, are versatile ingredients that can enhance the flavour and nutritional profile of plant-based dishes.

Oyster mushrooms are controversial
Oyster mushrooms, or Pleurotus species, are a group of gilled mushrooms. They are one of the most common types of cultivated mushrooms in the world and are also known as pearl oyster mushrooms or tree oyster mushrooms. Oyster mushrooms are eaten in a variety of cuisines and are especially popular in Chinese, Japanese, and Korean cooking. They are cultivated in greenhouses and are typically available all year round.
Oyster mushrooms are considered controversial due to their status as an invasive species. In 2018, a study by Andi Reisdorf examined the spread of non-native golden oyster mushrooms (Pleurotus citrinopileatus), which represented the first known case of a cultivated mushroom spreading quickly and widely outside of its native range. The study found that golden oyster mushrooms, native to the subtropical hardwood forests of eastern Russia, northern China, and Japan, had spread throughout the Midwest and Northeast of the United States and into Canada. This rapid and aggressive proliferation has led to concerns about the displacement of native decomposers and the potential threat to biodiversity.
The spread of invasive oyster mushrooms may be attributed to factors such as temperature, humidity, and other conducive conditions. There are concerns about the potential impact on native plants, fungi, and animal habitats. Oyster mushrooms are known to grow naturally on and near trees in temperate and subtropical forests, and their cultivation may contribute to their invasive nature.
While oyster mushrooms offer nutritional benefits, including being a good source of fiber, protein, vitamins, and minerals, their invasive status has raised concerns among experts. The potential ecological consequences of invasive fungi are being studied, and preliminary data suggests a heavy presence of golden oyster mushrooms in certain regions. The spread of these mushrooms and their impact on biodiversity and native species is a matter of ongoing research and discussion.

They are a good meat substitute
Mushrooms are a good meat substitute for several reasons. Firstly, they have a meaty flavour and texture, offering a satisfying bite that is hard to replicate with vegetables. This makes them an ideal substitute for meat in vegan cooking, as they provide a hearty and robust foundation for recipes. Oyster mushrooms, for example, can be breaded and fried until crisp, making them a perfect vegan alternative to meat in tacos or sandwiches. Similarly, shiitake mushrooms are renowned for their rich, umami flavour and distinct smoky notes, which can enhance the taste of any dish. Their meaty texture makes them a suitable meat substitute in a variety of recipes, from stir-fries to soups.
Secondly, mushrooms are a nutritious option, containing vitamins and minerals such as vitamin B6, folate, magnesium, zinc, and potassium, and vitamin D. Vitamin D is important for building strong bones, reducing inflammation, and improving immune function, and it is not easily found outside of animal products. Mushrooms are also a good source of protein, with common varieties containing around 2g of protein per 100g, comparable to most vegetables.
Thirdly, mushrooms are a sustainable and ethical choice. They can be grown 100% organically and without the use of animal products, contributing to a decrease in animal exploitation and environmental degradation. By substituting mushrooms for meat, individuals can actively reduce their reliance on animal farming, supporting a more humane approach to eating.
Lastly, mushrooms are versatile and can be used in a variety of dishes. They can be sliced, shredded, or left whole, and can be cooked in various ways, such as frying, grilling, or sautéing. They can take on different flavours and absorb spices and sauces, making them a tasty addition to any meal.
Overall, mushrooms make an excellent meat substitute, offering health, sustainability, and flavour benefits that satisfy taste buds while supporting ethical and compassionate eating habits.
