Mushrooms are unique organisms that spread through the creation and dispersal of spores. A single mushroom can produce billions of spores, each with unique genetics, which are released into the environment and carried by wind currents. These spores can also be spread by animals, insects, or through human activity. When spores land in a suitable environment, they germinate and grow into new mushrooms, forming vast colonies. The ability of mushrooms to spread their spores and decompose organic matter plays a critical role in nutrient cycling and the maintenance of ecosystems.

What You'll Learn
Spores travel via wind and air currents
Mushrooms spread by releasing spores, which are carried by wind and air currents. A single mushroom can produce up to one billion offspring in a single day, and each mushroom releases thousands of spores into its environment. These spores are so small that it takes 25,000 of them to cover a pinhead. They are released from the gills of the mushroom and dispersed by convectively created airflows.
The shape of the mushroom cap creates localized air currents, which help to sweep the spores high into the air. Spores typically deposit around mushrooms in asymmetric patterns, suggesting that one or two tongues of spore-laden air emerge from under the pileus. Numerical simulations show that strong spore dispersal requires shape asymmetry or temperature differentials along the pileus. In nature, wind speed tends to increase with height above the ground, so spores that travel upward may be more likely to reach dispersive winds.
Once released, the spores travel through the air until they land in a moist place, where they can germinate. Each spore then grows a network of fine threads called hyphae, which creep over and through its food source. The hyphae release chemicals that dissolve the food, and the resulting nutrients are absorbed by the growing fungus. Over a few weeks, the threads grow into a tangled mat, eventually forming a new mushroom.
While most mushrooms release spores from their gills, some have alternative methods. For example, puffballs release whiffs of spores when jostled or squeezed, and inkcaps liquefy and drip their spores. Some mushrooms benefit from grazing animals, which may deposit spores in a nutrient-rich substrate, or carry them through their fur or feathers. Insects can also aid in spore dispersal, either by being attracted to the mushroom and carrying the spores away, or by nesting inside the mushroom and spreading spores as they eat.

Spores spread through insects and animals
Mushrooms spread through spores, which are tiny cells that form on special hyphae. These spores are extremely small and lightweight, allowing them to be easily carried by air currents. While wind is the primary means of spore dispersal, they can also be spread through water and with the help of insects and animals.
Some mushroom spores are spread by water droplets from rain or streams, but others require assistance from insects and animals. Flies, for example, are attracted to the stinkhorn fungus due to its unpleasant odour. The flies feed on the fungus, carrying the spores until they are deposited in their faeces. This unique relationship between the stinkhorn fungus and flies ensures effective spore dispersal.
Additionally, certain mushrooms have evolved to grow on animal faeces, such as the fungus discovered on cave cricket faeces. This fungus, belonging to the group Kickxellomycotina, represents a new genus that inhabits the guts of animals. By colonizing the digestive systems of insects and other animals, these fungi can spread their spores through their faecal matter.
Beyond insects, larger animals also play a role in spore dispersal. For example, mushrooms that grow on animal dung rely on grazing animals for their dispersal. As grazing animals feed on grass or foliage, they may inadvertently ingest mushrooms or their spores. These spores then pass through the animal's digestive system and are dispersed in their faeces, potentially spreading to new locations.
In summary, while wind and water are the primary means of spore dispersal, insects and animals also play a significant role in spreading mushroom spores. Through their attraction to certain fungi, ingestion, or colonisation of their digestive systems, insects and animals contribute to the propagation of mushrooms in their respective ecosystems.

Spores germinate in moist environments
Mushrooms spread through the dispersal of spores, which are carried by wind currents. These spores are so small that it takes 25,000 of them to cover a pinhead. A single mushroom can produce up to one billion offspring in a single day. When spores land in a moist environment, they germinate and grow a network of fine threads called hyphae. The hyphae grow over and through the food, releasing chemicals that dissolve it. The growing fungus then absorbs the digested nutrients. Over time, the threads of hyphae develop into a tangled mat.
The process by which spores are released varies among different types of mushrooms. For example, puffballs release spores when they are jostled or squeezed, while inkcaps liquefy and drip spores. Some mushrooms have evolved to grow high up on trees, allowing them to spread their spores over greater distances. Mushrooms also influence the dispersal of their spores by creating localised air currents, even during the phase previously thought to be passive.
The shape of the mushroom cap, or pileus, plays a role in spore dispersal. Asymmetric shapes facilitate stronger dispersal, while symmetric shapes result in weaker dispersal. Numerical simulations have confirmed that strong spore dispersal requires either shape asymmetry or temperature differentials along the pileus.
In addition to wind, other vectors contribute to spore dispersal. Insects, such as midges and mosquitoes, are often attracted to the moist gills of mushrooms and inadvertently carry spores to new locations. Certain mushrooms, like stinkhorns, emit a rotting meat smell that lures flies. The spores then stick to the flies' bodies and are transported elsewhere. Grazing animals, such as squirrels and deer, may also aid in spore dispersal by carrying spores on their fur or ingesting the mushrooms and spreading the spores through their digestive systems.

Mushrooms produce billions of spores
The spores of mushrooms in the phylum Basidiomycota, including common cap and stem mushrooms, jelly fungi, puffballs, and porcini, are produced outside of club-like cells called basidia. In contrast, the spores of Ascomycota mushrooms, such as morels, corals, and cups, are produced internally within sac-like asci cells.
When spores land in a moist environment, they germinate and send out a network of fine threads called hyphae, which grow over and through their food source. The hyphae release digestive enzymes to break down the food, and the resulting nutrients are absorbed by the growing fungus. Over time, this network of threads becomes a tangled mat, forming the mycelium that produces mushrooms.
The dispersal and germination of spores are influenced by various factors. Some mushrooms benefit from height, such as those growing on trees, which helps them spread spores further. Certain mushrooms have evolved unique adaptations to attract insects or animals that inadvertently aid in spore dispersal. For example, stinkhorns emit a rotting meat smell that lures flies, causing them to carry spores elsewhere. Inkcaps liquefy and drip spores, while other mushrooms may benefit from passing animals that deposit their spores in nutrient-rich substrates.

Spores spread through temperature differentials
Mushrooms spread through spores, which are released into the environment and travel along wind currents. Mushrooms produce billions of spores, which are responsible for the spread and growth of new fungi.
Mushrooms use convectively created airflows to disperse their spores. The spores are initially drawn inward by a layer of inflowing warm air, and only after they have sedimented through this layer into the cold outflow beneath it do they start to travel outward. This process is influenced by the shape of the mushroom, with strong spore dispersal requiring shape asymmetry or temperature differentials along the pileus (the cap of the mushroom).
Numerical simulations have shown that when cooling is applied uniformly over the surface of the pileus, spores disperse weakly. This is due to the conservation of mass, which requires that the cold outward flow of spore-laden air be continually replenished with fresh air drawn in from outside of the gap. In contrast, when there is a temperature differential along the pileus, the cool air spreads along the ground, and the inflowing air travels along the undersurface of the pileus, creating the necessary conditions for spores to be drawn inward and then dispersed outward.
The presence of temperature differentials along the pileus, combined with the shape asymmetry of the mushroom, can create unidirectional dispersal patterns for the spores. The maximum spore dispersal distance is influenced by the temperature gradient between the left and right sides of the mushroom, as well as the gap height and overall shape of the mushroom.
The timing of spore release also plays a role in their dispersal. Some fungi release spores at specific times of day, and spores released during the day can fly for several days, while those released at night return to the ground within a few hours due to differences in turbulence. Additionally, the survival of spores during atmospheric transport is influenced by exposure to UV light, temperature, and humidity.

Frequently asked questions
Mushrooms spread by releasing spores. A single mushroom can produce up to one billion offspring in a single day. These spores are carried by wind currents and can also be spread by animals.
Mushrooms create localised air currents to sweep the spores into the air. The spores do not disperse symmetrically in all directions. Mushrooms are not simple machines for producing spores, but they do directly influence their dispersal.
Spores are microscopic and are often compared to seeds. However, unlike plants, where one seed produces one plant, a single mushroom releases thousands of spores, each carrying unique genetics.
Spores grow into mushrooms. When a spore lands in a moist place, it germinates and sends out a small filamentous thread called a hypha. This grows into a network of fine threads that creep over and through food. The hyphae release chemicals to digest the food, and the growing fungus absorbs the nutrients.
