Mushrooms are a type of fungus, and fungi are not plants. Fungi are members of the kingdom Fungi, which includes yeasts, rusts, smuts, mildews, molds, and mushrooms. Fungi are distinct from plants because they lack chlorophyll and have chitin in their cell walls. Fungi also do not photosynthesize; instead, they acquire food by absorbing dissolved molecules and digesting organic matter. Mushrooms can grow in potted plants, and their presence can indicate soil and plant health. Fungi in the soil can help plants by providing nutrients and allowing chemical communication between plants. However, some fungi can be harmful to plants and humans.

What You'll Learn
Fungi are not plants
Mushrooms are the fleshy, spore-bearing fruiting bodies of fungi. Fungi are not plants, despite the fact that they were once considered members of the plant kingdom due to similarities in lifestyle and morphology. Fungi and plants are both mainly immobile and can often be found growing in the same habitats, such as in soil or on moss.
However, fungi are now recognized as belonging to a separate kingdom from plants and animals, with distinct characteristics that set them apart. One key difference is their method of feeding. Plants make their own food through photosynthesis, using sunlight and carbon dioxide, whereas fungi acquire their nutrients by absorbing dissolved molecules from their environment, typically by secreting digestive enzymes. Fungi also lack chloroplasts, which are essential for photosynthesis, and instead store their food as glycogen, similar to animals.
Another distinguishing factor is the composition of their cell walls. Plant cells have cell walls made of cellulose, whereas fungi cell walls contain chitin, a substance also found in the exoskeletons of insects and other arthropods. This unique characteristic of fungal cell walls further emphasizes their separation from plants.
Furthermore, fungi and plants differ in their cellular structure and function. While plants may exhibit trap-like behavior, such as the Venus flytrap, their cells are fundamentally distinct from those of fungi. The classification of organisms into different kingdoms, such as Plantae for plants and Eumycota for true fungi, is based on these cellular and genetic differences, rather than solely on behavioral or morphological traits.
In conclusion, while fungi and plants share some similarities, fungi are not plants. Fungi belong to their own kingdom and exhibit unique characteristics in their feeding methods, cell wall composition, and cellular structure. These differences highlight the distinct nature of fungi and justify their classification as a separate group of organisms.

Mushrooms are fungi
The term "mushroom" is commonly used to refer to the fleshy, spore-bearing fruiting bodies of some fungi, particularly those with a stem, a cap, and gills that produce spores. These gills are located on the underside of the cap and release microscopic spores, aiding in the fungus's spread across the ground or its occupant surface. There are approximately 14,000 species of mushrooms, and they can vary widely in shape, size, and colour. Some common examples of mushrooms include the white button mushroom, shiitake, enoki, oyster mushrooms, and fly agarics.
Mushrooms have a long history of use by humans, dating back to prehistoric times. Ötzi the Iceman, a 5,300-year-old mummy found in the Austrian Alps, carried two species of mushrooms that may have been used as tinder or for medicinal purposes. Ancient peoples have also unknowingly consumed mushrooms as a food source for millennia, including in the preparation of leavened bread and fermented beverages. Today, mushrooms are valued for their culinary and nutritional qualities, with some varieties being prized for their delicious flavour and nutritional benefits.
In addition to their culinary uses, mushrooms also have important ecological roles. As saprophytes, they break down dead organic matter, preventing the accumulation of leaf litter and fallen branches. Certain types of fungi, known as mycorrhizal fungi, form mutually beneficial relationships with the roots of plants, aiding in water and mineral absorption. This symbiotic relationship is crucial for the survival of many trees, orchids, and other plant species. Furthermore, fungi have been utilised in the production of antibiotics and various enzymes used industrially and in detergents.

Fungi are beneficial to plants
Fungi are a diverse group of organisms, ranging from single-celled to complex multicellular organisms. They can be microscopic or present large fruiting bodies with underground systems that extend for miles or hectares. While some species can be detrimental to humans, animals, and plants, they are also responsible for important ecosystem services that benefit humans and the overall ecosystem.
Fungi are closely interlinked with vegetation and carbon and nutrient cycling. They play a major role in soil health and carbon sequestration. Fungi have the ability to transform nutrients in a way that makes them available for plants. Some fungi are decomposers, which means they break down plant and animal debris, cycling nutrients and increasing their availability in the soil. They can also propel nitrogen fixation and phosphorus mobilization, two of the main nutrients required for plant development and productivity.
Fungi form symbiotic relationships with approximately 80 to 90% of all plants, assisting them in acquiring nitrogen, phosphorus, micronutrients, and water in exchange for sugar produced by the plant. This mutually beneficial relationship is called a mycorrhizae network. Mycorrhizal fungi develop an extensive hyphal network in the soil, which can connect whole plant communities and offer efficient horizontal transfer of nutrients.
Fungi also protect plants by forming protective webs and nets around roots and even leaves to shield the host plant from harmful microorganisms. They can suppress plant root diseases and promote healthier plants by attacking plant pathogens with fungal enzymes. Additionally, they produce antibodies to reduce competition from other microorganisms and prevent the establishment of pathogenic organisms.

Mushrooms in potted plants
Mushrooms are the fleshy, spore-bearing fruiting bodies of fungi. They can be edible, poisonous, or unpalatable. The presence of mushrooms in potted plants can indicate soil and plant health. Mushrooms in potted plants can be a sign of good, healthy soil, as they break down nutrients, making them available to the plant. They digest spent organic material, such as insects, potting material, or even rotting roots, and release organic compounds back into the soil, providing plants with nutrients.
However, mushrooms in potted plants can also indicate a problem. Mushrooms indicate a high amount of moisture, and because they spore, they can spread and become a more significant issue. Mushrooms can also be toxic to people and pets, so it is essential to identify the type of mushroom and take appropriate action. If you have small children or pets, it is recommended to remove the mushrooms and the surrounding soil. This can be done by using gloves and replacing the top 2 inches of potting soil with new earth. Applying fungicides, either store-bought or homemade, is another option for removing mushrooms from potted plants.
Some common types of mushrooms found in potted plants include Flowerpot parasols (Leucocoprinus birnbaumii), Little Brown Mushrooms (Conocybe spp.), and Bird's Nest Fungi (Nidulariaceae). Flowerpot parasols are colourful saprotrophic mushrooms that feed on dead or decaying matter. Little Brown Mushrooms are also saprotrophic and are commonly found in potted plants. Bird's Nest Fungi are found in clusters and rely on rain to release their spores, which can be expelled up to three feet away.
While mushrooms can be beneficial to the health of potted plants, it is important to identify the type of mushroom and take appropriate precautions to ensure the safety of people and pets.

Lichens: a symbiotic relationship
Mushrooms are a type of fungus, and fungi are distinct from plants. Fungi were once considered primitive plants and were classified under the Plant Kingdom, but they are now considered a separate kingdom. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. They do not photosynthesize. Fungi are also the principal decomposers in ecological systems.
Lichens are composite organisms that arise from the symbiotic relationship between a fungus and an alga or cyanobacterium. Lichens come in many shapes, sizes, and colours and are often described as looking like miniature shrubs or bushes. They are incredibly resilient and can survive in a wide range of environments, from the Arctic to the equator, and from the driest deserts to the wettest rainforests. Lichens can also be found on every continent, including Antarctica.
The symbiotic relationship in lichens is a mutually beneficial one. The fungus provides protection and nutrients, such as minerals, to the alga or cyanobacterium, while the alga or cyanobacterium provides the fungus with carbohydrates and other chemicals it cannot produce itself. This relationship allows lichens to survive in extreme environments where neither organism could survive alone.
Lichens are important ecologically and have many uses. They are a food source for some animals and insects, and they can also be used by humans for natural dyes and in traditional medicines. Lichens are very sensitive to environmental changes and are often used as bioindicators to monitor air quality and pollution levels. They can also be used to date rocks and determine historical climate conditions.
Lichens are also of scientific interest due to their ability to survive in extreme environments. By studying lichens, scientists can gain a better understanding of the limits of life and the potential for life in other extreme environments, such as on other planets. Additionally, some lichens produce unique compounds that could have potential medicinal or industrial applications.
