Mushrooms are a type of fungus that are often found in gardens and forests. They are neither herbivores nor carnivores, but rather decomposers that break down dead plants and animals, absorbing nutrients and enriching the soil. They have root-like nodes called hyphae that break down organic matter and can secrete enzymes to break down complex cells. This process provides essential elements that nourish plants, improve soil water retention, and act as natural fertilizers. While mushrooms themselves are not herbivores, they are a part of the diet of many herbivorous animals, such as the southern cassowary of Australia, and play a crucial role in the natural cycle of nutrients.

What You'll Learn
Mushrooms are decomposers, not herbivores
Mushrooms are not herbivores. They are decomposers that break down dead plants and animals, absorbing nutrients and enriching the soil. They have root-like nodes called hyphae that effectively break down organic matter and can secrete enzymes to break down complex cells.
Mushrooms provide many benefits in gardening and composting. They nourish plants with essential elements, improve soil water retention, act as biological controls against pests and diseases, prevent soil compaction, and serve as a natural fertilizer that reduces reliance on synthetic fertilizers. They are an eco-friendly alternative to synthetic fertilizers as they do not deplete soil quality, contribute to eutrophication, or cause climate change.
Mushrooms are also consumed by a variety of organisms, including humans, who are omnivores, as well as certain insects, birds, and other animals. For example, slugs from various families, such as Philomycidae and Ariolimacidae, feed on mushrooms and slime molds. Some species of ants, such as Euprenolepis procera, have a diet consisting almost entirely of mushrooms. Several beetle families, including Erotylidae and Endomychidae, are specialists in consuming fungi.
Additionally, certain bird species, like jays (Perisoreus), including Canada jays (P. canadensis), Siberian jays (P. infaustus), and Oregon jays (P. obscurus), are known to eat mushrooms. The southern cassowary (Casuarius casuarius) of Australia also has bracket fungi as a significant part of its diet. Even some emus (Dromaius novaehollandiae) and brush turkeys (Alectura lathami) will consume certain types of fungi if offered.

Animals that eat mushrooms
Mushrooms are decomposers, breaking down dead plants and animals, and absorbing nutrients to enrich the soil. They are not herbivores. However, they are a source of food for many animals, including insects and mammals.
Slugs, snails, and isopods are among the invertebrates that eat mushrooms. Slugs are selective, choosing certain parts or developmental stages of fungi to eat. Slime molds and mushrooms are a food source for some species of slugs. Snails, on the other hand, help to decay wood, leaves, and waste materials, allowing new shoots to sprout through the forest floor.
Several insect species also eat mushrooms, including ants, beetles, flies, mites, and springtails. Some ants, such as Euprenolepis procera, a species from the rainforests of Southeast Asia, have a diet consisting almost entirely of mushrooms. Certain beetles, such as ambrosia beetles, farm fungi inside trees and feed on them. Mites and springtails have evolved to feed on fungi hyphae and will quickly consume entire mushrooms if given the chance.
Among mammals, squirrels, deer, bears, and rabbits are known to eat mushrooms. Squirrels, in particular, have a fondness for truffle-like fungi, which they dig up from the ground and leave to dry on tree limbs before consuming. Deer and bears can safely consume mushrooms that would be toxic to humans. Rabbits benefit from the rich nutrients provided by fungi, which they might otherwise miss out on by mainly consuming grass.

Mushrooms in manure
Mushrooms are neither herbivores nor carnivores. They are decomposers, breaking down dead plants and animals and absorbing nutrients to enrich the soil. They have root-like nodes called hyphae that break down organic matter and can secrete enzymes to break down complex cells. They are also consumers, and some even consider them to be producers.
Mushrooms can grow in a variety of substrates, including wood chips, sawdust, mulch, and even manure. Some mushroom species thrive in the nutrient-dense environment of animal manure. These mushrooms are called coprophilous fungi and hold ecological significance, playing a vital role in the natural world. They support both plant and animal organisms by feeding on feces and converting them into organic matter that can be reabsorbed into the earth.
Coprophilous fungi grow in herbivore manure, but not all types of manure meet their growth requirements. For example, Coprinus radiatus and Panaeolus campanulatus prefer horse dung because it is more acidic and decomposes more quickly. On the other hand, cow manure has a more neutral pH and is more dense in nutrients. It is also more decomposed due to the cow's complex digestive system. While some coprophilous fungi strictly adhere to a diet of feces, many fungi in the Sordaria and Podospora genera can grow on other decaying substrates.
The use of animal manure in mushroom cultivation has raised concerns about potential microbial contamination and food safety. Animal manure can be a source of human pathogens, and crop contamination with animal feces has been linked to foodborne outbreaks. However, there are no known cases of foodborne illness attributed to the consumption of fresh mushrooms grown in North America. The mushroom industry is working to provide scientific evidence that commercial composting can eliminate human pathogens in raw manures to address these concerns.
Mushroom compost, or spent mushroom compost, is also used in gardening and agriculture. It is slightly alkaline, with a pH of 6.5-7, making it suitable for a wide range of ornamental plants and vegetables. It is often used as a mulch and soil conditioner, spread in a 5 cm deep layer over the surface of the soil. Mushroom compost provides essential nutrients for plant growth, such as nitrogen, phosphorus, and potassium, while also promoting flower and fruit production due to its lower nitrogen levels.

Mushrooms as food for humans
Mushrooms have been consumed by humans since ancient times. The ancient Greeks believed that mushrooms gave warriors strength in battle, while the Romans considered them the "Food of the Gods". Chinese culture has long treasured mushrooms as a health food, an "elixir of life".
Mushrooms are a valuable food source because they are low in calories, carbohydrates, fat, and sodium, and are cholesterol-free. They are also a good source of selenium, potassium, riboflavin, niacin, vitamin D, proteins, and fiber. Their high protein content makes them a good addition to vegetarian diets.
Edible mushrooms include many fungal species that are either harvested wild or cultivated. Some of the more easily cultivated and common wild mushrooms available in markets include the common button mushroom, Chanterelle, Cremini, Enoki, Maitake, Morel, Oyster, and Porcini. Mushrooms that are more difficult to obtain, such as the truffle, matsutake, and morel, are collected on a smaller scale and are sometimes available at farmers' markets or local grocers.
It is important to note that some wild mushrooms can cause stomach upset, allergic reactions, or may even be poisonous. Therefore, it is generally safer to stick to supermarket varieties and avoid picking and eating raw wild mushrooms.

Benefits of mushrooms in gardening
Mushrooms are not plants, but rather fungi, and are therefore not herbivores. They are decomposers that break down dead plants and animals, absorbing nutrients and enriching the soil.
Sign of Healthy Soil
The presence of mushrooms in a garden is a sign of healthy soil. Mushrooms feed on organic matter, breaking down proteins, carbohydrates, and fats into essential elements that plants can easily digest. This process, called saprophytism, enriches the soil and makes the nutrients more accessible to plants.
Nourishment for Plants
Mushrooms have a symbiotic relationship with plants. They extend their reach in the soil by attaching to plant roots and creating filaments that expand the surface area of the roots. This helps the plants absorb more nutrients and water. In return, the plants supply sugars to the mushrooms, which they receive during photosynthesis.
Soil Structure and Permeability
The mycorrhizal filaments of fungi, including mushrooms, increase the structure and permeability of the soil. They generate organic compounds that bond the soil together, improve root growth, and move nutrients around.
Disease Suppression
Mushrooms also help suppress soil-borne pathogens and protect plants from root diseases. They keep diseases transmitted through the soil at bay and increase drainage.
Eco-Friendly Fertilizer
Mushrooms can serve as a natural fertilizer, reducing the need for synthetic fertilizers that can deplete soil quality and contribute to eutrophication and climate change. They provide an eco-friendly alternative that promotes sustainable agriculture and soil fertility.
While mushrooms offer numerous benefits to gardens, some gardeners may consider them a nuisance due to their impact on the aesthetic of specific garden designs. However, purposely growing mushrooms in a controlled manner can be a fun and beneficial hobby for gardeners.
