Mushrooms are fascinating organisms that have captivated humans for centuries with their diverse forms and ability to thrive in almost any habitat on Earth. From forests and woodlands to grasslands, sandy soils, and even challenging locales like high-altitude regions or acidic wetlands, mushrooms can be found in a multitude of environments. Each mushroom species has its preferred habitat and fruiting period, with some favouring the cold of winter and others the warmth of summer. Most mushrooms, however, prefer the moderate conditions of spring and fall. In this paragraph, we will explore the various habitats that mushrooms call home and the unique relationships they form with their environments.

Mushrooms grow in diverse habitats, from forests to grasslands, and even urban areas
Mushrooms are part of the Fungi kingdom and are neither plants nor animals. They grow in diverse habitats and can be found all year round, although individual species have their preferred fruiting periods. Some mushrooms, like certain winter varieties, thrive in cold weather, while others, like reishi and pink oysters, favour the warmth of summer. Most mushrooms, however, prefer moderate conditions and are therefore more likely to appear in spring and autumn.
Mushrooms can be found in forests and woodlands, grasslands, meadows, bogs, marshes, and even in challenging environments like high-altitude regions or acidic wetlands. They grow on decaying logs and stumps, leaf litter, and cultivated plants in agricultural areas. Some mushrooms are also found in urban settings, such as on sidewalks, lawns, and parks in cities.
The specific habitat of a mushroom is closely linked to its nutritional needs. Mushrooms obtain their nutrition from various sources, including decaying wood, organic-rich soil, and even certain types of plastics. Some mushrooms are parasitic and feed on living tissues, such as the roots of trees, orchids, and other plants. Other mushrooms form mutualistic relationships with trees, such as boletes, chanterelles, and amanitas, which are known as mycorrhizal fungi. These fungi help plants absorb water and minerals, and in return, the plants provide nutrients for the fungi.
The identification of mushrooms is a complex task due to the presence of poisonous varieties. The standard methods for identification involve examining characteristics such as juices upon breaking, bruising reactions, odours, tastes, shades of colour, habitat, habit, and season. Modern identification techniques are becoming increasingly molecular, but even with these advances, species-level identification requires significant effort.

They are selective about the trees they associate with
Mushrooms are selective about the trees they associate with. They form symbiotic relationships with trees, and some mushrooms are more selective than others. For example, ectomycorrhizal mushrooms are always found in association with woody plants, especially trees. However, not all woody plants can form these relationships with mushrooms. In forests, maple, ash, cedar, and a few other trees are non-ectomycorrhizal, but in tropical areas, most trees lack ectomycorrhizae.
Mushrooms are also found in grasslands, sandy soils, and challenging locales such as high-altitude regions or acidic wetlands. Each habitat, with its distinct conditions, is home to particular mushroom species, catering to the specific requirements of each. For example, grasslands and meadows are habitats for mushrooms like puffballs, waxcaps, and some agarics. Bogs and marshes are moist environments that are ideal for certain specialized mushrooms.
Mushrooms can also be found in agricultural areas, urban areas, and beaches and dunes. Some specialized fungi grow in sandy environments near the sea, and a few fungi grow in caves, often on bat or bird guano. On or within other organisms, fungi like the caterpillar-infesting Cordyceps and the Honey Fungus can attack plants, insects, or other fungi.
When collecting mushrooms for study or consumption, it is crucial to record the substrate (what it is growing on) and its associated trees. If the mushroom is growing on wood, it is important to identify the type of wood, or at least whether it is from a conifer or a hardwood. If the mushroom is on leaves or small stems, it is helpful to know the type of plant. Knowing the nearby woody plants is also necessary, as most mushrooms are selective about the trees they associate with.

Mushrooms grow on decaying wood, organic-rich soil, and even certain plastics
Mushrooms are part of the Fungi kingdom and are neither plants nor animals. Unlike plants, they cannot generate their own food through photosynthesis and rely on external food sources for energy. They grow in a variety of habitats, from forest floors to sand dunes, and are commonly found on decaying wood.
Decaying wood is a favourable environment for mushrooms because it provides them with the organic matter they need to grow and reproduce. The fungi decompose the wood, breaking it down into smaller pieces, and absorb the nutrients released during this process. This decomposition of wood by mushrooms is known as wood decay or rot.
One example of a mushroom that grows on decaying wood is the Armillaria fungus, commonly known as "Shoe-string root rot" due to the distinctive appearance of its mycelial fans. This fungus attacks and decays the roots and butts of trees, leading to potential tree failure and uprooting. However, it is important to note that Armillaria only affects dead wood and does not spread to live tissue.
In addition to decaying wood, mushrooms can also grow on organic-rich soil. This is because the soil provides the necessary nutrients and moisture for their growth. Mycelium and spores, which are responsible for mushroom growth, can remain dormant for extended periods and rapidly grow when moisture is introduced. Organic potting soil, in particular, has been observed to promote mushroom growth, with some users reporting the appearance of mushrooms in their potted plants.
Furthermore, mushrooms have been found to grow on certain plastics. Scientists have discovered several mushroom species that can consume polyurethane, a common ingredient in plastic products. For example, the fungus Pestalotiopsis microspora, found in the Amazon rainforest, can grow on polyurethane and use it as its sole carbon source. Another example is Aspergillus tubingensis, which was discovered at a general city waste disposal site in Pakistan and can break down polyester polyurethane. These plastic-eating mushrooms have potential in the fight against plastic pollution, as they can help degrade and clear plastic waste.

Some mushrooms grow on other organisms, like the caterpillar-infesting Cordyceps
Mushrooms are incredibly versatile and can be found in virtually every type of habitat on Earth, from forest floors to sand dunes. They are not limited by seasonality and can be found all year round, although individual species have their preferred fruiting periods. For example, some mushrooms, such as certain winter mushrooms, thrive in the cold, while others, like the reishi and pink oysters, prefer the warmth of summer. Most mushrooms, however, find the moderate conditions of spring and autumn particularly conducive to growth.
While some mushrooms grow on decaying wood, organic-rich soil, or even certain types of plastics, others grow on other organisms, like insects. One such example is the caterpillar-infesting Cordyceps, or Ophiocordyceps sinensis, which is a fungus that grows on the larvae of ghost moths. It is commonly referred to as the caterpillar fungus and is known by the name "dongchongxiacao" in Chinese, which translates to "winter worm, summer grass". This name is derived from the fungus's life cycle, where it infects and kills the ghost moth caterpillar, and then a fruiting stalk (mushroom) sprouts from the dead caterpillar's head. This fungus is found in the meadows and shrublands above 3,000 metres (approximately 9,800 to 16,400 feet) on the Tibetan Plateau and in the Himalayan regions of Bhutan, India, and Nepal.
The caterpillar cordyceps has a long history in Traditional Chinese Medicine (TCM) and is also used in traditional Tibetan medicine, where it is known as "yartsa gunbu". It is believed to have excellent balance as it is composed of both an animal and a vegetable. The fungus is highly valued, with prices skyrocketing in recent years, and it is now cultivated on an industrial scale for medicinal use. However, wild-collected cordyceps is often not true O. sinensis, even when the location and host insect match, which has led to the discovery of new species.
The difficulty in finding caterpillar cordyceps in the wild and the high demand for it have driven up its price. It is notoriously challenging to locate because it only sprouts for a few weeks in the spring, and it has specific habitat requirements. The natural habitat of the ghost moth caterpillars is grasslands, which provide ample cover, making them even harder to find. Additionally, attempts to cultivate this fungus by infecting cultivated caterpillars have been unsuccessful, further contributing to its scarcity.

They favour warm, shady, and moist conditions
Mushrooms are neither plants nor animals. They are part of the Fungi kingdom. They grow in a variety of habitats, from forest floors to sand dunes, and can be found all year round. However, most mushrooms favour warm, shady, and moist conditions.
Fungi, unlike plants, cannot generate their own food through photosynthesis. Instead, they rely on external food sources for energy. They decompose organic matter and absorb the nutrients released during this process. Mushrooms produce microscopic spores, which are spread by wind and animals, similar to how plants disperse their seeds.
When collecting mushrooms, it is important to record the substrate (what it is growing on) and its associated trees. This is because mushrooms are selective about the trees they associate with. For example, ectomycorrhizal mushrooms are always found with woody plants, especially trees. In addition, the means by which fungi obtain their nutrition can aid in their identification, as different species have different specialisations. For instance, the white mushroom Leucoagaricus leucothites, commonly found in lawns and open fields, should not be confused with the poisonous Amanita bisporigera.
While mushrooms are not strictly bound to particular seasons, individual species have their preferred fruiting periods. Some mushrooms, like certain winter varieties, thrive in the cold, while others, like pink oysters, favour the warmth of summer. Most mushrooms, however, find the moderate conditions of fall and spring particularly conducive to growth.
