Mushrooms are fungi that require different conditions to grow than plants. They are found throughout the world, with a wide variety in the Northern Hemisphere. Edible mushrooms are the fleshy fruit bodies of numerous species of macrofungi, with edibility defined by the absence of poisonous effects on humans and desirable taste and aroma. They can be harvested wild or cultivated, with over twenty species commercially cultivated in at least 60 countries. Mushrooms can be cultivated indoors or outdoors, with the most common method being inside large plastic bags filled with sterilized sawdust and wood chips. They can also be grown on logs, straw, or other cellulose sources, or in garden beds with compost.

Mushrooms can be cultivated in at least 60 countries
Mushrooms are cultivated in at least 60 countries. They are the fleshy fruit bodies of numerous macrofungi species. Edible mushrooms must meet specific criteria, including the absence of poisonous effects on humans and a desirable taste and aroma. They can be cultivated or harvested wild, but it is important to correctly identify wild mushrooms before consumption as some species are deadly poisonous.
Mushrooms are very adaptable and can grow in a wide range of temperatures, from 40 to 90 degrees Fahrenheit. They thrive in temperatures of around 70 degrees and require moisture. Most mushrooms prefer shade or dark places, which is why they are often found on forest floors. However, some mushrooms can grow in partial to full sun, such as those found on manure in a field. Mushrooms are more likely to adapt to less ideal conditions if they have a quality substrate to grow on.
Mushroom farming requires relatively little space, and they can be grown indoors on shelves. They can be grown on various materials, including logs, straw, or other cellulose sources, taking nutrients from the substrate as it decomposes. Garden beds full of compost are the perfect medium for growing mushrooms, and pre-mixed beds can be purchased, or you can make your own. The basic mix should include compost, wood chips, and other materials such as manure, rye meal, or vermiculite.
Oyster mushrooms (Pleurotus ostreatus) and shiitake mushrooms (Lentinula edodes) are excellent choices for first-time growers as they are easy to grow and delicious. They are commonly grown at an industrial scale, and shiitake mushrooms are cultivated for their nutritional properties, including proven tumor-reducing effects.

They grow in forests, on decomposing leaves, and at the base of trees
Mushrooms are the fleshy fruit bodies of several species of macrofungi. They are cultivated and consumed in at least 60 countries. Edible mushrooms can be harvested from the wild or grown commercially.
In the wild, mushrooms grow in forests, on decomposing leaves, and at the base of trees. They are highly adaptable and can grow on a variety of materials. They prefer shade and dark places, which is why they are commonly found on forest floors. Mushrooms that grow on forest floors are typically cap and stem varieties, such as morel and chestnut mushrooms. They take advantage of the decomposing organic matter in the soil.
Some mushrooms can grow in part to full sun, such as those found on manure in a field. They are more likely to adapt to less ideal conditions if they have a quality substrate to grow on. Mushrooms depend on a substrate—the material on which they grow—as they are unable to photosynthesise and produce their own food. Examples of substrates include logs, straw, or other cellulose sources.
Oyster mushrooms (Pleurotus ostreatus) are commonly grown at an industrial scale. They are also one of the easiest mushrooms to grow at home, along with shiitake mushrooms (Lentinula edodes). Shiitake mushrooms are cultivated for their nutritional properties and are known as "oak mushrooms" in Japanese. They are often grown on logs.
Identifying edible mushrooms can be challenging, as many benign mushrooms have a deadly doppelganger. It is important to correctly identify wild mushrooms before assuming they are edible.

Edible mushrooms can be grown on logs, straw, or other cellulose sources. Mushrooms are adaptable and can grow on a variety of materials. They are the fleshy fruit bodies of numerous macrofungi species. Edible mushrooms are defined by their absence of poisonous effects on humans and their desirable taste and aroma.
Shiitake mushrooms are a popular variety to grow, as they are delicious and perfect for soups, stews, and risottos. They are often grown on logs, but can also be grown in traditional beds filled with sterilized sawdust and compost. Oyster mushrooms are another variety that is commonly grown on logs. They are easy to grow and have a delicate briny taste and oyster-like appearance.
To grow edible mushrooms, you can purchase mushroom spawns and a substrate such as rye meal or sawdust. You can also make your own growing beds with materials such as manure, vermiculite, compost, and wood chips. Mushrooms require a warm, dark, and moist environment to grow, and they thrive when temperatures are around 70 degrees Fahrenheit. They do not require sunlight, so they can be grown indoors on shelves.
Mushrooms are typically found on forest floors, taking advantage of decomposing organic matter. They can also be found growing on trees or decomposing leaves. Mushroom farming requires relatively little space, and they are cultivated in at least 60 countries. Oyster mushrooms, in particular, are commonly grown at an industrial scale.

They require a moist environment to prevent the fruiting bodies from drying out
Edible mushrooms are the fleshy fruit bodies of numerous species of macrofungi. They are cultivated in at least 60 countries, with some species grown at an industrial scale. For example, Pleurotus species, the oyster mushrooms, are commonly grown at an industrial scale.
Mushrooms require a moist environment to prevent the fruiting bodies from drying out. Almost every part of a mushroom's life cycle depends on moisture availability, from spore germination to growth. Mushrooms are very adaptable and can grow in a wide range of temperatures, from 40 to 90 degrees Fahrenheit. They may begin growing in spring when temperatures are colder, but they thrive in a climate where temperatures hover around 70 degrees. Mushrooms also require shade or darkness, which is why they are often found on forest floors. However, some mushrooms can grow in partial to full sun, such as those found on manure in a field.
To create the right environment for mushrooms, growers need to monitor and control humidity levels. This is because mushroom fruiting bodies are extremely sensitive to humidity and depend on high moisture levels in the air to develop correctly. Low humidity can cause shrivelled, undersized, cracked, or improperly developed mushrooms. Small pins may dry out and fail to mature. Humidity levels of 80 to 95% are generally considered ideal during fruiting.
To maintain humidity, growers can use humidity tents, humidifiers, misting systems, and humidity domes. Humidity tents are enclosures that retain moisture and create a controlled environment. Humidifiers can distribute moisture evenly, but they should not be pointed directly at the mushroom fruiting bodies as this can cause condensation. Misting systems can also help maintain humidity, and growers can increase misting frequency if mushrooms become shrivelled or cracked. Spray bottles can be a low-tech solution for those with just a few fruiting blocks. Growers should also ensure proper ventilation to balance humidity levels and prevent mould and contamination.
In addition to humidity, growers need to consider other factors such as light and substrate moisture. Mushrooms have different light needs—some require darkness, while others need 12 hours of light to fruit properly. Indirect light encourages consistent cap development and avoids the harsh effects of direct sunlight, such as drying and uneven growth. The substrate, or growing medium, must stay evenly moist, but not soaked, to support full colonisation and pinning. Letting the substrate dry out can stall mushroom growth and development.
