Do mushrooms have consciousness? This question has sparked intriguing discussions and scientific investigations, challenging traditional notions of consciousness and intelligence. While some may associate mushrooms and fungi with folklore and superstition, recent studies suggest that these organisms possess a form of consciousness and intelligence. They can make decisions, learn, and exhibit spatial recognition and short-term memory capabilities. This has led to the concept of “minimal selfhood,” which proposes that consciousness can exist without a brain or neural tissue, instead relying on self-maintenance, self-reproduction, and self-containment. As we explore the complexities of fungal behavior, we may need to broaden our understanding of consciousness and recognize the unique intelligence of these fascinating organisms.

What You'll Learn
Mushrooms are associated with witchcraft and superstitions
Mushrooms and other fungi have long been associated with witchcraft and superstition. This is due in part to their peculiar characteristics, such as their poisonous and psychoactive properties, as well as their rapid and mysterious overnight growth. According to German folklore, witches dance inside fairy rings of mushrooms, while a French fable warns of enormous, bulging-eyed toads that curse anyone who dares step into these "sorcerer's rings".
The magical reputation of fungi has contributed to the reluctance of scientists to explore the idea of fungal consciousness. However, recent experiments have provided evidence that fungi possess a form of intelligence. They can operate as individuals, make decisions, learn, and exhibit short-term memory capabilities.
Fungi have been shown to respond to their environment, demonstrating a level of sensitivity and reactiveness. They can detect ridges on surfaces and adapt their growth patterns accordingly. This ability to interact with their surroundings and other organisms indicates a level of consciousness.
Furthermore, the vast networks of mycelium that make up most of a fungus's body can communicate with each other, sharing information and making decisions based on their collective experiences. This has led some to propose the concept of minimal selfhood, suggesting that fungi possess a simple form of intelligence or a primitive mind.
While the idea of fungal consciousness may challenge traditional scientific viewpoints, it is important to recognize that consciousness exists along a continuum. By expanding our understanding of intelligence and consciousness beyond human-centric perspectives, we can appreciate the unique cognitive abilities of fungi and their potential contributions to our understanding of intelligence.

Mushrooms can make decisions
The idea that mushrooms and fungi are conscious is a controversial one. For a long time, the consensus among most scientists was that only big-brained animals were conscious, and that some form of nervous system was essential for an organism to possess consciousness. However, this view has been challenged in recent years, with some scientists arguing that different versions of consciousness exist across a continuum of species, from apes to amoebas.
Fungi, including mushrooms, have been shown to exhibit cellular consciousness. They can react to their environment, pursuing food and recognising threats. They can also adapt to their environment, showing something similar to classical conditioning. For example, pathogenic fungal mycelia have been shown to modify their growth form to become more invasive as an infection develops.
Fungi have also been shown to possess short-term memory. In one experiment, when a mycelium located a block of beechwood, it grew out from the same side of the block that had previously allowed it to access food. This suggests that the fungus remembered that growing from a particular side of the block had resulted in a food reward. Fungi have also been shown to possess spatial recognition, with networks of mycelium, or thin, thread-like strands called hyphae, covering vast areas.
Fungi can also make decisions. According to a study published in the journal Fungal Ecology, fungi are capable of basic shape recognition and decision-making throughout the networks they build. The study's lead author, Yu Fukasawa, stated that "fungi can make decisions" and that "the differences in how they solve problems compared to humans is mind-blowing". In another experiment, fungal mycelia were found to alter their developmental patterns in response to interactions with other organisms, choosing efficiency and strategic growth to avoid wasting resources.
While the idea of fungal consciousness is intriguing, it is important to approach it with caution. The study of fungal behaviour has often been relegated to the fringes of 'real' science due to its association with witchcraft and longstanding superstitions. Additionally, defining consciousness in a way that is fair to every type of organism is a complex task, and the concept of sentience in mushrooms and fungi remains a subject of ongoing debate.

Mushrooms have short-term memory
While the concept of consciousness in mushrooms and other fungi may seem far-fetched, there is a growing body of evidence to support the idea that they exhibit a form of consciousness. This is based on their ability to express sensitivity to their environment, make decisions, and alter their developmental patterns in response to interactions with other organisms.
Fungi have long been associated with witchcraft and superstition, perhaps due to their peculiar appearance and the toxicity of certain species. However, recent experiments have revealed that they do possess a form of intelligence. For example, in one experiment, a mycelium that had previously located a block of beechwood and received a food reward was then placed in a fresh tray. The mycelium emerged from the same side of the block that had previously led to a food reward, indicating that it remembered the action that had resulted in success. This demonstrates spatial recognition, memory, and intelligence.
Fungi have also been observed to respond to their environment when invading a host. For instance, certain species that target humans have been found to modify their growth form to become more invasive as the infection develops. While these responses are genetically programmed rather than learned behaviours, they demonstrate the fungus's ability to adapt to its environment.
Furthermore, in experiments conducted by Yu Fukasawa, colonies of one species of fungus were exposed to high temperatures and then subjected to a second heat shock. The colonies that had prior exposure were better able to cope with the second heat shock compared to 'uneducated' colonies, indicating a form of cellular memory that lasted up to twelve hours.
These findings suggest that mushrooms and other fungi possess a form of short-term memory and learning capability, supporting the idea that they exhibit a type of consciousness or intelligence. However, it is important to note that the study of fungal consciousness is still a developing field, and more research is needed to fully understand the nature and extent of their cognitive abilities.

Mushrooms can learn
While the idea of mushrooms having consciousness has often been associated with witchcraft and folklore, recent studies have shown that mushrooms and fungi do exhibit some form of consciousness and learning.
Fungi have been observed to operate as individuals, make decisions, and exhibit short-term memory. In one experiment, a mycelium located a block of beechwood, and when placed in a fresh tray, it emerged from the same side of the block that had previously allowed it to find food. This suggests that the fungus remembered its prior success and sought to repeat it, demonstrating spatial recognition, memory, and intelligence.
Fungal mycelia also respond to their environment, particularly when invading a host. For example, species that target humans have been observed to modify their growth form to become more invasive as the infection develops. While these responses are genetically programmed and not learned behaviours, the fungus can still adapt to its environment, showing a similarity to classical conditioning.
Furthermore, in experiments with fungal memory, colonies of a particular species of fungus exposed to high temperatures were better able to withstand a second heat shock compared to those that were not "educated." This cellular adaptation demonstrates a form of learning and short-term memory.
The concept of minimal selfhood, a pattern of conscious behaviour that does not require a brain or neural tissue, is also relevant to the discussion of fungal consciousness. Fungal hyphae, the microscopic threads that make up the body of a fungus, react to their environment, pursue food, and recognize threats. They exhibit sensitivity and consciousness through the rapid motion and complex organization of their vesicles, which are fluid-filled spheres enclosed by a membrane.
While the study of fungal behaviour and cognition may have been considered fringe science in the past, recent evidence suggests that mushrooms and fungi possess a simple form of consciousness and learning.

Mushrooms can solve problems
Mushrooms have long been associated with witchcraft and folklore, and they are often the subjects of longstanding superstitions. However, in recent years, scientists have discovered that mushrooms and fungi exhibit remarkable problem-solving abilities and possess a form of intelligence.
Fungi have been shown to operate as individuals, make decisions, learn, and possess short-term memory. For example, in experiments, fungi have demonstrated spatial recognition and memory. When a mycelium located a block of beechwood, it emerged from the same side of the block that had previously led to a food reward. This indicates that the fungus remembered its prior success and was able to repeat it.
Fungi also show decision-making abilities and alter their developmental patterns in response to interactions with other organisms. For instance, pathogenic fungal mycelia modify their growth form to become more invasive as an infection in a human host develops. This demonstrates their ability to respond to their environment and adapt their behaviour accordingly.
Fungi can also solve problems related to environmental pollution and ecosystem regeneration. They can survive in toxic environments and consume pollutants such as oil, making them useful for mycoremediation. Additionally, their spores attract insects that lay eggs, fostering the development of a thriving environment and jump-starting the recovery of formerly toxic zones.
Furthermore, mushrooms offer solutions to challenges in agriculture and pest control. They can be used as a natural, non-toxic pesticide that repels insects without causing harm to other animals or the planet. This provides an alternative to chemical-filled pesticides, which can have negative impacts on the ecosystem.
In conclusion, mushrooms and fungi exhibit a range of problem-solving abilities that contribute to ecosystem health, environmental cleanup, and sustainable agriculture. While the study of fungal consciousness and cognition is still evolving, there is growing evidence that these organisms possess a form of intelligence that allows them to adapt, learn, and make decisions in response to their environment.

Frequently asked questions
While the concept of mushrooms having consciousness might seem far-fetched, there is some evidence to suggest that they do. Mushrooms and other fungi have been shown to operate as individuals, make decisions, learn, and possess short-term memory. They also show reactiveness and sensitivity to their environment, which can be interpreted as expressions of cellular consciousness. However, the level and nature of their consciousness differ from that of animals and may be more akin to a primitive or minimal form of consciousness.
The implications of acknowledging mushroom consciousness could be far-reaching. It challenges our understanding of intelligence and consciousness, suggesting that consciousness may exist on a continuum across various species, including those without complex brains or nervous systems. It also raises questions about the sentience of plants and fungi, potentially impacting human interactions with these organisms, such as vegan diets and conservation efforts.
The study of mushroom consciousness expands our understanding of intelligence by demonstrating that intelligence can manifest in diverse ways beyond the human model. It highlights the concept of \"distributed intelligence,\" where different parts of an organism can exhibit individual decision-making abilities, as seen in the strategic growth patterns of fungal mycelial networks. This knowledge may even help us comprehend the workings of our own complex minds.
