While mushrooms in the wild do not walk, mushroom corals can move on their own. They inflate and deflate their tissues to move, detach from their base and use the water flow to float, or crawl around. In a fascinating experiment, a certain type of mushroom was found to mimic brain cell activity and control tiny vehicles. In another instance, a mushroom was given a robot body and it ran wild. In the video game Avowed, mushrooms are shown walking in a line.

Mushroom walks are led by mycologists, who teach survival skills
Mushroom walks are led by mycologists who teach participants valuable survival skills, such as identifying edible mushrooms in the wild. Mycologists like Tradd Cotter, who runs Mushroom Mountain in South Carolina, have a keen eye for spotting mushrooms in their natural habitat. They know to look under fallen leaves, in hollowed tree trunks, and towards the tree canopy, where mushrooms are most likely to be found.
On mushroom walks, mycologists teach participants how to identify edible mushrooms and differentiate them from poisonous varieties. While most wild mushrooms are edible, it is crucial to know the difference to stay safe. Some safe mushrooms may have an unpleasant taste, while some poisonous mushrooms can cause severe gastrointestinal distress or even be deadly. Mycologists emphasize the importance of expert identification and joining mushroom clubs to gain knowledge from experienced foragers.
Mushroom walks often involve exploring trails in forests or native environments, where participants can learn about the vital roles that fungi play in ecosystems. Mycologists may also discuss the historical uses of mushrooms, current scientific trends, and innovations in the field. These walks cater to a diverse range of participants, including nature lovers, teachers, wilderness educators, chefs, and biology students.
In addition to identification skills, mycologists may provide insights into the medicinal properties of mushrooms and how to prepare them. They might also share their knowledge of sustainable harvesting practices to ensure the preservation of fungal ecosystems. Some mycologists, like Jeremy Hegge, focus on understanding taxonomy and global foraging practices. Jeremy's walks in the Yarra Valley are known for their educational and engaging approach, fostering a deeper appreciation for the biodiversity of the fungal kingdom.
Overall, mushroom walks led by mycologists offer a unique opportunity to learn valuable survival skills, gain a deeper understanding of fungi, and explore the fascinating world of mushrooms in their natural habitat.

Common mushrooms found on walks include Boletus or Boletales, Amanitas, and Cordyceps
While mushrooms are not capable of walking, they are commonly found on walks and hikes through forests and woods. Some of the most common mushrooms found on these walks include Boletus or Boletales, Amanitas, and Cordyceps.
Boletus or Boletales, commonly known as boletes, are one of the most common mushrooms you are likely to find on almost any walk. They are characterised by small pores on the spore-bearing surface, instead of gills, which makes them easy to identify. Boletus edulis, also known as the cep, penny bun, or porcino, is a highly sought-after edible mushroom within this family. It is widely distributed in the Northern Hemisphere across Eurasia and North America and is considered a delicacy in many cuisines.
Amanitas, on the other hand, include some of the world's most toxic mushrooms. They are identified by their gills instead of pores and are another common find on walks in the woods. Amanita muscaria, for example, is often found alongside Boletus edulis, though the reason for this association is not yet clear.
Lastly, Cordyceps is a unique type of fungus that grows from a beetle or other insect. Finding a Cordyceps on a walk is quite exciting, as it indicates that truffles may be present nearby.

Mushrooms are decomposers that create soil
Mushrooms are fungi, and fungi are decomposers. Decomposers play a critical role in the ecosystem by breaking down dead organic materials into simpler inorganic materials. This process of decomposition creates vital nutrients that are added back to the soil, which plants need to grow.
Mushrooms are nature's recyclers, breaking down complex organic materials into more elementary substances: water and carbon dioxide, plus simple compounds containing nitrogen, phosphorus, and calcium. This process of decomposition creates soil.
In a healthy ecosystem, mushrooms play an important role in creating and maintaining soil levels. For example, in the Appalachian Mountains, it takes mushrooms anywhere from 500 to 800 years to make an inch of soil. Over time, the topsoil in this region has decreased in depth due to the work of mushrooms.
While mushrooms are not the only decomposers in nature, they are particularly important in forests. Some other decomposers include bacteria, earthworms, termites, and millipedes. These organisms work together to break down dead plant and animal matter, keeping the ecosystem clean and providing essential nutrients for new growth.

Mushroom corals can move on their own, inflating and deflating their tissues
Mushroom corals, or corallimorphs, are a type of soft coral commonly found in reef aquariums. They are solitary marine animals from the family Fungiidae and are capable of benthic locomotion, or movement, in both the ocean and aquariums. Unlike other corals, mushroom corals can move, and this movement is often in search of a more suitable location with optimal lighting and water flow conditions.
Mushroom corals can move in any direction they want, and they do so by inflating and deflating their tissues. This process, known as "coordinated pulsed inflation locomotion", involves the tissues at the bottom of the corals inflating and creating lift. The corals also increase their surface area by using their ventral foot and manipulating their tissues through contraction and twisting motions to propel themselves forward. After jumping to a new location, the corals deflate back to their typical size.
In addition to this unique form of locomotion, larger mushroom corals may also detach from their base and use the water flow inside the aquarium to float toward their desired location. Once they have found a new spot, they attach their base securely to a rock or substrate. Smaller mushroom corals tend to move faster than larger ones, as larger coral movement is often determined by wave action rather than tissue inflation and deflation.
Mushroom corals typically move during the night when the aquarium lights are switched off, and they can be very unpredictable. While most small mushroom corals can right themselves if they overturn during movement, larger corals may need assistance. If a mushroom coral is left overturned for too long, it can die. Therefore, it is recommended to only interfere by flipping the coral the right way up and allowing it to move freely to its preferred location.

King oyster mushrooms exhibit electrophysiological activity similar to REM sleep
Mushrooms, specifically king oyster mushrooms (Pleurotus eryngii), exhibit intriguing behaviours that resemble sleep patterns observed in humans. The mycelial networks of these fungi flicker and pulse, generating electrochemical responses akin to the activity of human brain cells during REM sleep. This discovery has sparked curiosity among researchers from Cornell University and the University of Florence, who conducted a series of experiments to unravel the mysteries of mushroom electrophysiology.
The experiments involved placing a culture of king oyster mushrooms in control of tiny vehicles. To everyone's surprise, these vehicles began to exhibit twitching movements and navigated across a flat surface. This phenomenon provided valuable insights into the mushrooms' electrophysiological capabilities, suggesting that their responses to environmental cues could be translated into instructions for mechanical devices.
The research delved into the realm of biohybrid technology, exploring the fusion of biology and technology. By harnessing the extracellular electrophysiology of P. eryngii mycelia, researchers employed algorithms to prompt mechanical responses in mobile devices. This innovative approach has the potential to revolutionise fields such as environmental monitoring, medical diagnostics, and search-and-rescue operations, showcasing the versatility and adaptability of biohybrid systems.
The implications of this discovery extend beyond the laboratory. With the ability to create living machines that can perceive and interact with their surroundings, ethical considerations come into play. It raises questions about the rights and regulations associated with biohybrid technology, challenging us to thoughtfully navigate the intersection of biology and robotics for the betterment of various industries and human life.
