Mushrooms are a type of fungus that has been consumed and used for medicinal purposes for thousands of years. They are neither plants nor animals, despite their historical classification as plants. This misconception persists due to similarities in lifestyle and morphology, such as their growth in soil and resemblance to mosses. Fungi, including mushrooms, are now recognised as a separate kingdom, distinct from plants and animals. So, are mushrooms non-vascular?

What You'll Learn
Mushrooms are a type of fungus
Fungi are structurally different from plants and animals. Their cell walls contain chitin, unlike the cellulose found in plant cells. They are often studied alongside plants due to similarities in lifestyle and morphology, such as being mainly immobile and growing in soil. Mushrooms, in particular, form conspicuous fruit bodies that sometimes resemble plants like mosses.
Despite these similarities, fungi are more closely related genetically to animals than to plants. They are the principal decomposers in ecological systems, breaking down decaying matter and enabling nutrient cycling. This process is integral to the ecosystem, as it supports the functioning of peatlands, provides global carbon sinks, and facilitates water purification and biodiversity.
Mushrooms are a well-known type of fungus consumed by humans for thousands of years as food and medicine. They are a good source of vitamin D, antioxidants, and anti-inflammatory compounds. They are also recognised for their culinary properties, enhancing savoury flavours in dishes.
In summary, mushrooms are a type of fungus with distinct structural, genetic, and ecological characteristics. They play an essential role in ecosystems and have various benefits for human health and cuisine.

They are neither plants nor animals
Mushrooms are not vascular as they lack the specialized tissues, xylem and phloem, that are characteristic of vascular plants. This is because mushrooms, and fungi in general, are not plants at all in the traditional sense; they form their own distinct kingdom in the tree of life.
While they were once classified as plants, this was due to their stationary nature and similarities in structure, such as having a network of thread-like hyphae that can resemble plant roots. However, this classification changed as scientists discovered key differences in their cellular structure and nutrition.
Fungi, including mushrooms, obtain their nutrients by absorbing them from their environment, usually through decomposing organic matter. They secrete enzymes that break down complex organic compounds into simpler substances that can be absorbed directly through their cell walls. This process is very different from how plants obtain nutrients, which is primarily through photosynthesis, converting sunlight into energy, and taking in water and minerals from the soil.
The absence of chlorophyll, a pigment necessary for photosynthesis, is another distinguishing factor that showcases why mushrooms and fungi are separate from plants. Instead of producing their own food, fungi are degraders and recyclers, playing a critical role in ecosystems by breaking down dead organic material and returning nutrients to the soil, which new plants can then use.
In addition, the cell walls of fungi are composed of chitin, a polymer also found in the exoskeletons of insects and crustaceans, further highlighting the unique nature of these organisms. So, while mushrooms may have some physical similarities to plants, their method of obtaining nutrients, their cellular composition, and their unique role in ecosystems firmly establish them as distinct from the plant kingdom. This classification as non-vascular, non-photosynthetic organisms highlights their unique evolutionary path and specialized ecological niche.

They have medicinal and nutritional value
Mushrooms are a type of fungus that has been consumed as food and used for medicinal purposes for thousands of years. They contain a wide range of nutrients and antioxidants, which provide numerous health benefits.
Mushrooms are a good source of vitamins, including B vitamins such as thiamine, riboflavin, B6, and B12. They also contain vitamin D, which is important for maintaining healthy bones and absorbing calcium. The amount of vitamin D in mushrooms varies depending on their exposure to UV light or sunlight. Wild mushrooms like chanterelles and morels typically have higher levels of vitamin D, while those grown in dark conditions, such as white button, shiitake, and oyster mushrooms, have lower amounts. However, exposing cultivated mushrooms to UV light or sunlight can increase their vitamin D content.
In addition to vitamins, mushrooms provide essential minerals. They are also a source of protein and antioxidants, which can help prevent cellular damage and reduce the risk of cancer. Certain varieties of mushrooms, such as shiitake, oyster, maitake, and king oyster, have higher amounts of ergothioneine, an amino acid and antioxidant. Consuming mushrooms regularly may help lower the risk of cancer, with some studies suggesting a reduction of up to 45% when eating just 18 grams of mushrooms daily.
Mushrooms are also beneficial for heart health. They are naturally low in sodium, which helps maintain healthy blood pressure. Additionally, certain types of mushrooms, like shiitake, contain compounds that help lower cholesterol levels. The polysaccharides in mushrooms act as prebiotics, stimulating the growth of beneficial gut bacteria and contributing to overall health.
Some specific types of mushrooms are associated with additional health benefits. For example, Lion's mane mushrooms are known for their potential brain health benefits, including reducing inflammation and improving cognitive function. Chaga mushrooms are believed to lower blood pressure, and reishi mushrooms are thought to boost the immune system.
While mushrooms offer a range of medicinal and nutritional advantages, it is important to remember that not all mushrooms are safe for consumption. Some species, such as the Amanita mushroom, are toxic to humans. Foraging for wild mushrooms requires knowledge of safe and unsafe varieties to avoid toxicity.

They are decomposers and contribute to nutrient cycling
Mushrooms are a type of fungus that plays a crucial role in the food chain and holds significant ecological importance. Fungi are the principal decomposers in ecological systems, and mushrooms are no exception. They break down organic matter and recycle nutrients back into the ecosystem, maintaining soil fertility and nutrient cycling, which benefits plant growth.
Mushrooms secrete enzymes that break down complex substances like lignin and cellulose, turning them into simpler forms that can be absorbed by other organisms. This process facilitates the release of carbon, nitrogen, phosphorus, and other nutrients locked inside dead organic matter. The newly released nutrients are then absorbed by the mushroom mycelium and redistributed into the soil ecosystem.
Through mycorrhizal associations, mushrooms form mutually beneficial relationships with trees and other plants. These associations enhance nutrient absorption and water uptake for the plants, while the plants provide sugars as food for the mushrooms. This symbiotic relationship is particularly important in forest ecosystems, where mushrooms play a vital role in decomposing wood and other tough materials.
Without mushrooms, the accumulation of organic matter would impede nutrient recycling and lead to imbalances in the environment. They are essential for maintaining the health and biodiversity of ecosystems, as well as sustaining life on Earth. The decomposition process performed by mushrooms and other decomposers ensures a steady flow of energy and nutrients within ecosystems.

They are studied alongside plants
Mushrooms are a type of fungus. Fungi were once considered members of the plant kingdom due to similarities in lifestyle and morphology. For example, both fungi and plants are mainly immobile and often grow in the soil. Mushrooms, in particular, can form conspicuous fruit bodies that sometimes resemble plants such as mosses.
However, fungi are now considered a separate kingdom, distinct from both plants and animals. Fungi lack chloroplasts, a unifying feature of plants. They are also genetically more closely related to animals than to plants.
Despite this, fungi are still studied alongside plants in the field of biology known as mycology. Mycology is concerned with the study of fungi, including their taxonomy, genetics, biochemical properties, and use by humans. Mycology branches into the field of phytopathology, the study of plant diseases, as the vast majority of plant pathogens are fungi. Fungi are also important in controlling plant diseases caused by different pathogens. For example, species of the filamentous fungal genus Trichoderma are considered effective biological control agents for crop disease management.
Fungi have a symbiotic relationship with plants, especially trees, and provide benefits such as disease tolerance, improved growth, mineral nutrition, and fertilizer utilization. They are also important decomposers in ecological systems and play a crucial role in the decomposition of organic matter and nutrient cycling and exchange in the environment.
