Mushrooms are fungi that reproduce by spreading spores. For a long time, it was believed that mushrooms simply dropped their spores and hoped for wind currents to carry them. However, recent research has revealed that mushrooms play a more active role in their reproduction by creating their own wind. This process, known as evaporative cooling, involves the evaporation of moisture on the mushroom, which leads to a temperature decrease and the creation of water vapor. The resulting air currents, or miniature gales, can carry spores up to 4 inches in any direction, even in the absence of natural wind. This ability to generate wind enhances the chances of spores finding new, moist locations to grow, contributing to the propagation of mushroom species.

Mushrooms create their own wind
Mushrooms have long been thought to spread by passively dropping their spores, which would then be picked up by the wind and carried away. However, this theory has been challenged by new research, which suggests that mushrooms play a more active role in spreading their seeds.
The ability to create their own wind helps mushroom spores travel to new locations and begin growing. This is especially important for mushrooms that live in environments with little to no wind, such as on the forest floor, under logs, or in tight spaces. By creating their own wind, mushrooms can ensure that their spores have a better chance of finding a moist location to land and grow.
The discovery that mushrooms create their own wind was made by researchers Emilie Dressaire and Marcus Roper, who used high-speed videography, laser lights, mathematical modelling, and temperature and water loss readings to study the spread of spores from mushrooms. Their findings suggest that mushrooms are not just passive machines for producing spores but are instead complex organisms that can actively manipulate their local environments.

Spores are lifted by wind
It was previously believed that mushrooms reproduced by simply dropping their spores and relying on gusts of wind to carry them. However, recent research has revealed that mushrooms play a more active role in their reproduction by creating their own wind to disperse spores.
Mushrooms typically reside in environments where wind is absent, such as on the forest floor, under logs, or in confined spaces. To overcome this challenge, they have evolved the ability to generate their own air currents, ensuring the dissemination of spores to new locations where they can grow.
The process by which mushrooms create wind involves the evaporation of moisture on their surface. As the liquid transforms into vapour, it consumes heat energy, leading to a cooling effect. This cooling causes the air to become denser and initiates airflow. Additionally, the evaporation produces water vapour, which is less dense than air. The combination of these two forces, the denser cold air flowing outwards and the lighter water vapour, creates convective cells that facilitate the movement of air around the mushroom.
The wind generated by this process is strong enough to lift the spores away from the mushroom, enabling them to travel significant distances. This mechanism allows mushrooms to disperse their spores even in unfavourable conditions, enhancing their chances of successful colonisation and survival.
The discovery of mushroom-generated wind sheds light on the intricate strategies employed by these fungi to perpetuate their species. By mastering the art of wind creation, mushrooms ensure their reproductive success and contribute to the rich diversity of the Fungi kingdom.

Evaporation creates wind
Evaporation is the process of a liquid changing into a gas or vapour. When a molecule near the surface absorbs enough energy, it escapes and enters the surrounding air as a gas. This process is important for the exchange of energy in the Earth-atmosphere system, producing atmospheric motion and, consequently, weather and climate.
Mushrooms, which are the reproductive organs of fungi, have been found to create their own wind through evaporation. They release water vapour, which cools the air locally. This cooling effect creates convective cells that move the air around in the mushroom's vicinity. The resulting wind helps the mushroom's spores to be lifted and carried away, even in still air.
The process begins with the release of moisture from the mushroom. As the moisture evaporates, it consumes heat energy, leading to a cooling effect. This cooling causes the air to become denser and begin to flow and spread out. Additionally, the evaporation creates water vapour, which is less dense than air. These two forces, the denser cold air and the less dense water vapour, work together to generate a current of air, or a miniature gale, that propels the spores away from the mushroom.
The ability to create wind through evaporation allows mushrooms to take an active role in spreading their spores. This mechanism enhances the chances of the spores finding new, moist locations to land and initiate growth. It is particularly advantageous for mushrooms growing in environments with limited air movement, such as on the forest floor, under logs, or in tight spaces. By generating their own wind, mushrooms can ensure the dispersal of their spores even in still or inhospitable conditions.

Wind helps spores travel
It was previously believed that mushrooms reproduced by simply dropping their spores and relying on the wind to carry them away. However, recent research has revealed that mushrooms play a more active role in their reproduction by creating their own wind to disperse spores.
Mushrooms often reside in environments where wind may not be prevalent, such as the forest floor, under logs, or in confined spaces. To overcome this challenge, they have evolved the ability to generate their own air currents. This capability enhances the chances of their spores finding new, moist habitats where they can take root and flourish.
The process by which mushrooms create wind involves the evaporation of moisture on their surfaces. As the water evaporates, it consumes heat energy, leading to a cooling effect. The resulting water vapour is less dense than the surrounding air. This disparity in density, coupled with the tendency of cold air to flow and disperse, generates air movement.
The wind created by mushrooms is sufficiently powerful to lift and propel their spores. The spores can travel in any direction, including upward, covering distances of up to 4 inches (10 centimetres) from the mushroom. This mechanism ensures the effective dispersal of spores even in unfavourable conditions.
The discovery of mushroom-generated wind sheds light on the sophisticated strategies employed by these organisms to ensure their propagation. It showcases the ingenuity of fungi in manipulating their environment to enhance their survival and dispersal capabilities.

Spores are dispersed by wind
Mushrooms are known to live on the forest floor, under logs, or in tight spaces where wind is not expected to reach. For a long time, it was thought that mushrooms spread by passively dropping their spores, which would then be picked up by gusts of wind and carried away. However, recent research has shown that mushrooms play a more active role in spreading their spores. They do this by creating their own wind.
Mushrooms create their own wind through the process of evaporation. When the moisture on a mushroom's surface evaporates, the mushroom cools down. This is because heat energy is consumed when liquid water becomes vapour. As the air around the mushroom cools, it flows and disseminates, creating wind. This wind is strong enough to lift the spores off the mushroom and carry them away.
The evaporation of water also creates water vapour, which is less dense than air. This creates a second force that helps carry spores out of the mushroom and gives them additional lift. Together, these two forces can carry spores up to 4 inches (10 centimetres) in any direction, even upwards.
By creating their own wind, mushrooms can control their local environment and improve the chances of their spores finding a new, moist location to land and begin growing. This ability to generate wind and control air movement shows that mushrooms are more complex than previously thought and highlights their ingenuity as engineers of their own survival.
