Mushrooms are unique organisms that are neither plants nor animals. They spread through spores, which are like natural seeds. These spores are microscopic and are released into the environment by mushrooms. They can spread through wind, evaporation, or by hitching a ride on animals. Some mushrooms grow high up on trees to spread their spores further, while others have a smell that attracts insects or animals, which then carry the spores elsewhere.

Mushrooms spread by creating their own wind
Mushrooms are unique organisms that are neither plants nor animals. They are fungi, which means they are made up of cells with DNA contained in a nucleus bound by a membrane. Fungi do not photosynthesize like plants, so they cannot produce their own food. Instead, they secrete digestive enzymes into their environment and absorb the nutrients released.
Mushrooms are known to spread by creating their own wind to disperse their spores. This process is known as "making wind" and helps give spores a better chance of finding a new, moist location to land and start growing. Mushrooms often live in tight spaces where wind wouldn't typically reach, so creating their own airflow is essential for spore dispersal. By using evaporation, mushrooms can induce a bit of airflow, and their cap shapes further aid in creating localized air currents that sweep the spores high into the air.
The ability to create wind for spore dispersal is not unique to a specific type of mushroom but is believed to be a capability of all mushroom-producing fungi. This was demonstrated by Roper and colleague Emilie Dressaire, who visualized spore spread from various mushroom species using laser light and a high-speed camera. Their study revealed that mushrooms create their airflow by taking advantage of convective cells and temperature differentials.
The dynamics of spore dispersal were further analyzed through simulations, which showed that strong spore dispersal occurs with shape asymmetry or temperature variations along the mushroom's cap. These simulations approximated the 2D dynamics of spore tongues, which were typically deposited around mushrooms in asymmetric patterns. The simulations also considered the conservation of mass, where the outward flow of spore-laden air must be replenished with fresh air drawn in from outside the gap.
Overall, the process of mushrooms creating their own wind to spread spores is a fascinating example of fungal adaptation. By manipulating airflow and temperature, mushrooms can effectively disperse their spores and ensure their survival and propagation in various environments.

Spores can be spread by insects
Mushrooms are the "'fruiting bodies' of fungi, and they spread spores in a variety of ways. Mushrooms release thousands of spores into their environment, each carrying unique genetics. Fungi are not passive organisms; they actively manipulate their environment to spread their spores. One way they do this is by creating localized air currents with their caps, which help sweep the spores into the air. Fungi also spread their spores by shooting them out at high speeds in rapid succession.
Some mushrooms grow high up in trees, using the height to spread their spores further. Stinkhorns, for example, attract flies with a rotting meat smell. The flies get coated in sticky, spore-filled gleba, which they then carry elsewhere. Inkcaps, on the other hand, liquify and drip spores that are below them. Some mushrooms benefit when grazing animals deposit their spores in nutrient-rich substrates, and they may have adapted to germinate after passing through the digestive system. Russula and Lactarius species are often gathered by squirrels and stashed in nests, so spores may hitch a ride on the fur of squirrels or deer.
Insects play a significant role in spreading mushroom spores. Tricholoma sulphureum has a bizarre 'coal gas' smell that attracts flying insects, which then pick up spores. Midges and mosquitoes are often found enjoying the moist gills of mushrooms, and their larvae nest inside mushrooms, eating them from within and potentially spreading spores. Certain species of ants have been gardening mushrooms for over 50 million years. The new queens carry chunks of the mycelium in their mouths to new nests. A unique fungus survives by 'bewitching' male flies into mating with dead female flies. The longer the female carcass has lain and rotted, the greater the success of this strategy.

Spores can be spread by grazing animals
Mushrooms are fungi, a unique group of organisms that are neither plants nor animals. Fungi obtain nutrients from other organic material, often other organisms, and play a critical role in decomposition, breaking down complex organic compounds such as lignan.
Mushrooms spread through spores, which are microscopic and can be spread in various ways. One method is through the movement of grazing animals. Some mushrooms benefit from being eaten by grazing animals, as they deposit spores in a nutrient-rich substrate, allowing the spores to germinate and grow. For example, Russula and Lactarius species are often gathered by squirrels and stashed in their nests. The spores may also hitch a ride on the fur of animals such as squirrels or deer.
In addition to animal dispersal, mushrooms also spread spores through mechanical and physiological mechanisms. Some mushrooms grow high up on trees to increase the distance of spore spread. Others, like stinkhorns, attract flies with a putrid odour, coating them with sticky, spore-filled gleba that is then carried elsewhere. Inkcaps, on the other hand, liquify and drip spores to the ground below. Mushrooms also take advantage of air currents to sweep spores high into the air, even when falling from a short height.
The spread of spores through grazing animals is an effective strategy for mushrooms to disperse and grow in new environments.

Spores can survive cold temperatures
Mushrooms spread through spores, which are like natural seeds. Each mushroom releases thousands of spores into its environment, and each spore carries unique genetics. Spores can spread through the wind, and some mushrooms create their own airflow to spread spores. Mushrooms also spread through insects, grazing animals, and squirrels and deer, which carry spores on their fur.
Mushrooms have unique ways of spreading their spores. For example, stinkhorns attract flies with their rotting meat smell, and the flies carry the sticky, spore-filled gleba elsewhere. Inkcaps liquify and drip spores, while Russula and Lactarius species are gathered by squirrels and stashed in their nests.
Mushroom caps are shaped to create localized air currents that sweep spores into the air. Mushrooms also rely on evaporation to induce airflow. Additionally, spores do not always disperse symmetrically, and numerical simulations show that strong spore dispersal requires shape asymmetry or temperature differentials.
While spores can survive cold temperatures, living mycelium may go dormant in the soil over winter. The ability of spores to survive cold temperatures allows for their spread in colder climates and during winter.

Mushrooms are cultivated in sterile conditions
The mushroom grower's challenge is to create an environment that is as sterile as possible. This is difficult because there are many sources of contamination, including the air, cultivation tools, human breath, clothes, hands, and even the mushroom cultures or substrates themselves. The human body is the greatest source of contamination, with human hands and clothes harbouring bacteria and spores that can ruin crops. To mitigate this, growers should shower and use hand sanitiser before handling mushrooms, and wear clean clothes, including a lab coat or scrubs, a face mask or mouth covering, and laboratory gloves.
The mushroom growing environment should be kept clean and airtight to prevent pests that may spread mould spores. The best way to reduce undesired spores and other airborne contamination in the workspace is through the use of a laminar flow hood, which is a workbench that includes a filter pad, fan, and a High-Efficiency Particulates Air (HEPA) filter. If a flow hood is not an option, a still air box is the next best choice for small-scale projects and is a popular choice for home cultivators.
The mushroom substrates, which provide the mushroom mycelium with the nutrients it needs to develop, must be moist and nutrient-rich. However, these conditions also encourage the growth of moulds and germs, so sterilisation or pasteurisation may be necessary to minimise the risk of contamination. Sterilisation involves heating the substrate to temperatures above 120°C under pressure to kill any living or dormant contaminants. Pasteurisation, a less intensive process, heats the substrate to temperatures between 65°C and 85°C for 1.5 to 2 hours, reducing the population of bacteria so that the mushroom species has an advantage.

Frequently asked questions
Mushrooms spread by releasing spores into the environment. Each mushroom releases thousands of spores, each carrying unique genetics. These spores are spread through convectively created airflows, evaporation, and the movement of livestock and insects.
Mushroom spores are similar to the natural seeds of a mushroom. They are microscopic and invisible to the naked eye. Spores develop into a fluff that, when planted into horse manure and covered with soil, grows into mushrooms.
Mushrooms create their own airflow to spread spores, which helps them travel long distances and find new locations to grow. Spores can also hitch a ride on the fur of animals or be carried by insects.
