Mushrooms are a nutritious food source with many health benefits, but they are not plants, animals, or bacteria. They are fungi, and they require different conditions to grow than plants. Unlike plants, mushrooms do not make their own food through photosynthesis, so they do not need sunlight to grow. Instead, they rely on food from the environment around them to get the energy to grow. They consume organic matter, or natural nutrients, from the soil around them. Mushrooms can be grown at home or on farms, and they grow quickly and efficiently, converting plant matter into edible mushrooms.

What You'll Learn
Mushrooms are fungi, not plants
Mushrooms are biologically distinct from plant- and animal-derived foods. They are classified as part of the fungi/mycology food kingdom, separate from plants/botany and animals/zoology. This classification is based on their unique nutrient profile and culinary characteristics. Mushrooms produce spores, similar to pollen or seeds, which allow them to spread or travel through the wind. They do not produce seeds like plants.
The fungi kingdom includes yeasts, moulds, mildews, rusts, and smuts, and it is estimated that over 140,000 species of wild mushrooms exist worldwide, with around 3,000 edible varieties. Mushrooms are native to North America and Europe and are known for their delicate flavour and meaty texture. They grow in the wild, but it is safer to consume farm-grown varieties as some wild mushrooms are toxic or even fatal if ingested.
Mushrooms are a good source of selenium, B vitamins, calcium, and potassium. They also contain beta glucan, which acts as a prebiotic, promoting a healthy gut environment. Additionally, they are low in calories and packed with essential vitamins and minerals, making them a nutritious addition to any diet. Mushrooms have been used as food and medicine for centuries and are now cultivated in 33 states in the United States, with most mushroom farms being family-owned.

They eat organic material
Mushrooms are a type of fungus, and they feed on organic material. They are not plants, animals, or bacteria, but belong to their own kingdom. They are the fleshy fruit of an underground fungus. Fungi are heterotrophic, meaning they rely on food from their environment to get the energy to grow.
Mushrooms absorb organic compounds from their surroundings. They secrete enzymes that break down large organic molecules into smaller molecules that can be absorbed as nutrients. This process is similar to how plants use photosynthesis to make food. Mushrooms, however, do not have this ability and must rely on external sources for their nutrition. The long thread-like hyphae that make up mycelium release digestive enzymes into the dead or living organic matter around them. These enzymes break down large organic molecules into smaller, simple molecules that the hyphae can then absorb.
Different types of mushrooms feed on specific organic materials or food sources to get their nutrients. Saprotrophic mushrooms and toadstools, for example, thrive on decaying organic matter like wood, plants, and even dead animals. They are decomposers and play a crucial role in the ecosystem by breaking down this dead organic matter. Mushrooms grown by farmers use recycled byproducts from other agricultural sectors, such as crushed corn cobs, cottonseed hulls, soybean hulls, peanut hulls, and cocoa shells. This provides a solution to waste management challenges for other agricultural operations.
Forest mushrooms, though they may look fragile, are powerful decomposers of dead wood and other tough plant material. They absorb nutrients from their environment efficiently due to their high surface area-to-volume ratios. They also release hydrolytic enzymes that break down large organic molecules such as polysaccharides, proteins, and lipids into smaller molecules that can be absorbed by the fungal cells.

Different mushrooms eat different foods
Mushrooms are a type of fungus, and they are not plants, animals, or bacteria. They are unique in that they belong to a separate kingdom of their own. While plants make their food through photosynthesis, fungi like mushrooms absorb organic compounds from their surroundings. This is why mushrooms are often found on top of the soil or on the surface of a food source.
Forest mushrooms, for example, decompose dead wood and other tough plant material. They release hydrolytic enzymes that break down large organic molecules into smaller molecules that can be absorbed as nutrients. Truffles, another type of fungus, grow underground attached to the roots of trees and have a stronger taste and smell than other mushrooms.
Saprotrophic mushrooms and toadstools thrive on decaying organic matter such as wood, plants, and even dead animals. They are essential decomposers in the ecosystem, breaking down dead organic matter. Mushrooms are also classified into food grouping systems by their use as a vegetable, and they are increasingly being used in plant-based diets.
Mushrooms have a unique nutrient profile and are packed with essential vitamins, minerals, and antioxidants. They are a good source of selenium, vitamin D, zinc, and B vitamins, which are essential for immune function, cell growth, and overall health. Adding just a few mushrooms to your daily diet can provide numerous health benefits, including a reduced risk of cancer and improved brain and heart health.

Mushrooms need carbon and nitrogen to grow
Mushrooms are a type of fungus that feed on nutrients from their environment. They are not plants, animals, or bacteria, but they belong to their own separate kingdom. Mushrooms are heterotrophic, meaning they rely on food from their environment to get the energy to grow. They do not have stomachs, so they must digest their food externally before absorbing nutrients through the cell walls of the hyphae. To do this, the long thread-like hyphae that make up mycelium release digestive enzymes into the dead or living organic matter around them. These enzymes break down large organic molecules into smaller simple molecules that the hyphae can absorb.
Different types of mushrooms need different food sources, and some are fussier than others. Mushrooms require a substrate that provides the right mix of nutrients, including sugar, starch, lignin, fats, protein, and nitrogen. A fibrous, woody substrate like cellulose, lignin, and hemicelluloses is ideal as it provides plenty of carbon, the main food source for mycelium.
The other main macronutrient required for mushroom growth and energy is nitrogen. The ideal substrate should contain one to two percent nitrogen. Small amounts of magnesium, potassium, calcium, sulfur, and phosphorus are also necessary for mushroom growth. A slightly acidic substrate with a pH level of about 5 to 6.5 is ideal, and good aeration in the substrate is crucial as mycelium needs good air exchange to grow and completely colonize the substrate.
Additionally, maintaining the right moisture content is essential for mushroom growth. The substrate should have a moisture content of 50 to 70 percent; if conditions are too dry, mycelium will stop growing. Under the right conditions, hyphae will rapidly grow to access more nutrition.

Some mushrooms grow on food sources
Mushrooms are a type of fungus, and they are not plants, animals, or bacteria. They have their own kingdom. They are the fleshy fruit of an underground fungus. Fungi are heterotrophic, meaning they rely on food from their environment to get the energy to grow. Fungi absorb organic compounds from the environment around them.
Different types of mushrooms feed differently and use specific organic materials or food to get their nutrients. Some mushrooms grow on food sources. For example, saprotrophic mushrooms and toadstools thrive on decaying organic matter like wood, plants, and even sometimes dead animals. They are decomposers who play a crucial role in the ecosystem by breaking down dead organic matter. Truffles, another type of fungus, grow underground attached to the roots of trees.
Mushrooms can grow above ground, on top of the soil, or on the surface of a food source. The substrate, or surface, on which mushrooms are grown needs to provide plenty of carbon, the main food source for mycelium. The ideal substrate also needs to contain one to two percent nitrogen, as well as small amounts of magnesium, potassium, calcium, sulfur, and phosphorus. A slightly acidic substrate with a pH level of about 5 to 6.5 is ideal. Good aeration in the substrate is also necessary, as mycelium needs good air exchange to grow and completely colonize the substrate.
Mushrooms are native to North America and Europe and are known for their delicate flavor and meaty texture. They are also widely known for their health benefits, as they are packed with essential vitamins and minerals, making them an excellent addition to a balanced diet.
