Researchers have been deciphering the electrical signals fungi emit, which display patterns similar to human nerve impulses. This mushroom “language” reveals a wondrous array of electrical patterns resembling words and has the potential to revolutionize fields such as biocomputing.

Yet untangling this cryptic chatter is no small task. This fungi language may be closer to being understood than we think.

What is Fungi Language?

Despite lacking a central nervous system, fungi communicate through electrical impulses sent across thin filaments known as mycelium that form a dense web within the soil. This communication has been shown to be incredibly complex, but it is not yet clear whether fungi communicate in a manner that resembles language.

A new study suggests that mushrooms do, in fact, talk to each other using electrical signals. Computer scientist Andrew Adamatzk at the Unconventional Computing Laboratory at the University of West of England analyzed the electrical spikes generated by the colonies of four different species of mushroom, including enoki, split gill, ghost, and caterpillar fungi. The researchers inserted tiny electrodes into substrates colonized by the mushrooms and recorded their corresponding electrical spike trains.

The results were striking. Adamatzk discovered that the electrical spikes produced by the mushroom colonies often occurred in clusters that resembled a lexicon of words. The average word length for the various species was similar to the average word length of certain human languages, and he found that the most complex sentences were generated by split gill fungi. Enoki and ghost fungi produced shorter sentences, which could indicate differences in dialect or a simple lexicon.

Adamatzk also compared the lengths of these electrical spike trains to the frequency of word onset times in spoken language, and found that the pattern of the fungal spikes was very close to that of the spoken word. This led him to suggest that the fungi were in fact communicating, though it is important to note that this classification is based solely on the number of spikes occurring in a given train of electrical pulses, and not on their specific configurations.

Whether the fungal “words” are actually a form of language is still unknown, but it’s certainly intriguing to speculate that they may be able to convey some information. Future studies should look at the diversity of fungi vocabulary, and try to determine if there is a grammatical structure that allows for the discerning of words. Even if it turns out that the spores are only communicating about the presence of nutrients in their environment, this is still a step toward a better understanding of the consciousness of the world around us.

The Challenges

The enigmatic world of mushroom chatter is as fascinating as it is mysterious. However, the road to deciphering this hidden language is rife with obstacles, as mushrooms can be quite fragile when growing and often requiring fresh air exchange. The first hurdle is the sheer number of possible combinations of electrical spikes and pulses. This is why researchers have to carefully analyze the data from the mycelial networks of various fungus species. The next challenge is identifying interspecies variations, if any exist, and the grammatical constructions of these fungal words. Finally, a thorough and detailed classification of these spike trains is required to fully understand the message being conveyed by the fungus.

Despite not having a nervous system, as many animals do, mushrooms have managed to communicate with each other using jolts of electricity sent across wispy threads called hyphae. These hyphae form a thin network called mycelium that connects different fungi colonies in the soil. These electrical impulses, which are similar to those transmitted by neurons in the human brain, allow fungi to share information about food and potential dangers with their neighbors.

Researchers have been able to record these electrical signals, and they have now analyzed them in order to create a linguistic model for the fungal language. The findings are published in the journal Royal Society Open Science. Computer scientist Andrew Adamatzky from the University of the West of England led the study. He plugged electrodes into the mycelial networks of four different fungus species and found that they were able to send messages to each other via their electrical patterns.

Adamatzky and his team were able to group these electrical signals into “trains” that could be interpreted as words. They also analyzed the length of these “words” and found that they were remarkably similar to the average word lengths in English.

The researchers were able to identify a core lexicon of words from the spike train data, but they are still unsure what the messages are about. It is likely that fungi use this communication to inform their neighbors of threats and possible food sources, but this remains speculation.

The emergence of a fungal language is one of the most exciting developments in natural history. It may even provide a key to understanding how complex the communication systems of other multicellular organisms are.

The Answers

All of the many shapes, colors, culinary and wellness uses that we love about mushrooms owe their existence to a tiny yet crucial component: spores. These microscopic particles serve a function analogous to that of seeds in plants, releasing into suitable environments from fruiting bodies and germinating into mycelia that can eventually produce new mushrooms.

The release of spores is an incredibly rapid process, with a spore traveling the distance of a basketball court in just four seconds — faster than a bullet fired from a gun. This speed of travel is due to the minuscule mass of the spore, and to the force of gravity on it.

As they are released, spores also emit pheromones that attract other fungi with similar pheromones. This is how mycelia communicate to form partnerships and negotiate relationships ranging from fusion to indifference to physical exclusion and chemical antagonism.

Researchers have even been able to decode some of the language of spores by watching them with high-speed video cameras. One such experiment showed how a single mushroom can launch 31,000 ballistospores per second, which amounts to some 2.7 billion spores a day. During this process, spores change shape in order to be dispersed by water droplets, a mechanism called “ballistic ejection.”

While a lot of the specifics of this process are still unknown, a paper published earlier this year by mycologist Katie Field and others detailed how tiny changes in spore shape affect the trajectory of the resulting airborne droplets. This is the first time researchers have broken down this process in frame-by-frame detail. They found that the changing shape of spores caused profound alterations in the shape of water droplets, which then affected the trajectories of the spores.

Mushroom cultivators use spore prints (also called culture syringes) to inoculate substrates and kickstart the cultivation of new fruiting bodies. While spores can also be introduced through other methods, including monotubs and garden beds, culture syringes are the best option for precise application.

The spore season in Worcester begins around mid-June, peaking in September, and then declining rapidly through October to low levels by December. Spore risk rises during warm weather and when there is rainfall, especially if it’s light or showery.

The Future

Fungi are already transforming our world in amazing ways. They play critical roles in nature and are a source of inspiration for human cultures, from ancient shamanic rituals to the latest innovations in home mycology. And with the recent breakthroughs in decoding mushroom electrical signals, they have even more exciting potential for our future.

While most people associate spore prints with mushroom identification, they can be used in many other creative applications. Artists can use them to add a unique pattern or texture to their works, and scientists can extract pigments from them to create subtle shades for fabrics and papers. And of course, they’re also useful for identifying specific species—though color alone isn’t always enough to pinpoint the exact species. Other features like cap shape and stem structure, habitat, and mycological family can be helpful in confirming identification.

Mushrooms communicate through a network of interconnected hyphae, and researchers have discovered that they send electrical signals between individual mushrooms to warn them of danger, signal the location of food, or even to share nutrients. These mind-boggling communications reveal that fungi aren’t just solitary organisms, and suggest that they have some level of social interaction and intelligence.

One of the most interesting discoveries in this field is that fungi can seed rain using their spores. By attracting water droplets in the air, they can initiate rainfall—a process known as “spore rainmaking.” While other types of particles, such as pollen, bacteria, and dust, seed rain clouds, this phenomenon is a lot more efficient and does not use pollutants, which can negatively impact ecosystems.

Fungi can do more than just inspire us — they can actually be used to address global challenges. For example, a team of mycologists has been working on an ambitious project to identify potential sources of edible mushrooms in the event of a global catastrophe, such as an asteroid strike or nuclear war. Considering how devastating these events would be to traditional agriculture, this research could prove lifesaving.
