Mushrooms, or fungi, are often thought of as simply living fiber-optic cables that allow plants and trees to communicate with each other. However, research suggests that mushrooms are much more complex than that. They are actively perceiving, interpreting, and signaling, and they do this with a wide range of beings. Mushrooms have been found to communicate with each other using electrical impulses that may form a sort of language. Furthermore, mushrooms have been found to gain new abilities via horizontal gene transfer, where a third party, such as a bacterium, absorbs some of the genome of a host and then passes those cells onto another host.

Mushrooms may communicate using electrical impulses
Mushrooms are the reproductive organs of mycelium, a decentralized, weblike structure of branching tubes. Fungi, including mushrooms, are in constant communication with a wide range of beings, including plants and insects. They are actively perceiving, interpreting, and signaling, and they do so by creating and interpreting a cacophony of chemical and electrical signals.
Research by Professor Andrew Adamatzky of the University of the West of England in Bristol suggests that mushrooms influence the mycelium's internal bioelectrical signals, which may form a sort of “language". Adamatzky analyzed the patterns of electrical spikes generated by four species of fungi: enoki, split gill, ghost, and caterpillar fungi. He found that these spikes often clustered into trains of activity, resembling vocabularies of up to 50 "words". The distribution of these "fungal word lengths" closely matched those of human languages.
The most likely reasons for these waves of electrical activity are to maintain the fungi's integrity or to report newly discovered sources of attractants and repellents to other parts of their mycelium or to hyphae-connected partners such as trees. The firing rate of these impulses increases when the hyphae of wood-digesting fungi come into contact with wooden blocks, raising the possibility that fungi use this electrical "language" to share information about food or injury.
Furthermore, mushrooms have been found to gain certain abilities via horizontal gene transfer. For example, distantly related mushrooms gained the ability to produce a dangerous toxin through horizontal gene transfer from another, possibly extinct, mushroom. This process involves a third party, such as a bacterium, absorbing some of the genome of a host it is infecting and then passing those cells onto another host.

Fungi transfer genetic information via horizontal gene transfer
Fungi are capable of communicating with each other and with other organisms, such as trees. They can also transfer genetic information via horizontal gene transfer (HGT). HGT is a process where genes, gene clusters, or entire chromosomes are transferred between organisms, and it plays a significant role in the evolution of fungal species.
Horizontal gene transfer in fungi was previously believed to be of minimal importance, especially in eukaryotes. However, recent evidence suggests that HGT significantly impacts the evolution of eukaryotic genomes, particularly in unicellular organisms. Fungi, being a densely sampled eukaryotic lineage, are ideal for studying eukaryotic evolutionary mechanisms, including HGT.
Bioinformatics-based methods are commonly employed to identify HGT in fungal genomes. These techniques enable researchers to investigate the mechanisms by which genetic material is laterally transferred into fungal species. By studying HGT events in fungi, scientists can gain insights into the impact of these transfers on fungal evolution and their implications for the fungal tree of life.
Furthermore, horizontal gene transfer in fungi can have far-reaching consequences. The transfer of individual genes or gene clusters can influence niche specification, disease emergence, and shifts in metabolic capabilities. For example, the transfer of a catabolic gene from bacteria to filamentous eukaryotes has been observed, showcasing the ability of fungi to acquire genes from contrasting organisms.
In conclusion, fungi exhibit a sophisticated ability to transfer genetic information via horizontal gene transfer. This process plays a crucial role in their evolution and adaptability, contributing to our understanding of eukaryotic evolutionary mechanisms and the complex dynamics of the fungal kingdom.

The wood-wide web is a network of interconnected trees
Mycorrhizal fungi form symbiotic relationships with tree roots, connecting different trees and creating a vast underground network. This network enables trees to share water, carbon, nitrogen, and other nutrients. For example, in a healthy forest, a sapling growing in a shady area relies on nutrients and sugar from older, taller trees sent through the mycorrhizal network.
There are two main types of mycorrhizal fungi involved in this process. Firstly, Ectomycorrhizal fungi are primarily associated with trees in temperate and boreal forests, such as pines, firs, and oaks. They form a sheath around the tree roots without penetrating them. Secondly, Arbuscular mycorrhizal fungi are more common in tropical and subtropical forests and many crops. They penetrate the root cells, forming tree-like structures called arbuscules.
The discovery of the wood-wide web has important implications for conservation efforts. It highlights the intricate relationships that exist in nature and challenges us to view ecosystems as intricate webs of cooperation and mutual support. As we face global challenges like climate change and biodiversity loss, this perspective can help us develop more holistic and effective approaches to environmental stewardship.
Furthermore, the wood-wide web has similarities to human language. Research has found that the electrical spikes in fungi often cluster into trains of activity, resembling vocabularies of up to 50 "words". However, scientists caution against anthropomorphizing trees or overstating their "intelligence." They emphasize that while communication in the wood-wide web is real, it is a result of evolutionary processes rather than conscious decision-making.

Mushrooms can communicate with multiple species of fungi
Mushrooms, or fungi, are spore-producing bodies that are the reproductive organs of mycelium, a decentralized, weblike body of branching tubes. Fungi are constantly sensing, learning, and making decisions as they grow. They communicate within their own species and with other organisms.
Fungi communicate within their own species to coordinate actions across their network. They do this through a stream of chemicals, nutrients, and electrical impulses. Research by Professor Andrew Adamatzky of the University of the West of England in Bristol suggests that these impulses may form a sort of "language."
Fungi also communicate with other organisms. They can send out pheromones and grow toward other fungi that seem attractive. When two mycelia meet, they communicate to negotiate their relationship, which can range from fusion to form a partnership to indifference or exclusion. Fungi may also communicate with plants through mycorrhizal mutualisms, sharing water and food with plant partners.
Adamatzky's research analyzed the electrical spikes generated by four species of fungi: enoki, split gill, ghost, and caterpillar fungi. He found that these spikes often clustered into trains of activity, resembling vocabularies of up to 50 words. The distribution of these "fungal word lengths" closely matched those of human languages. However, Adamatzky acknowledges that it is unclear what the mushrooms are saying to each other, and more research is needed before we can truly understand this as a language.

Mushrooms use chemical signals to communicate
Mushrooms, or fungi, are the reproductive organs of mycelium, a decentralized, weblike body of branching tubes. Fungi are organisms that live in complex relationships with other life forms, and they could not exist without communication.
Fungi communicate through chemical signals, electrical impulses, and pulsing behaviour. The chemical signals are a stream of chemicals, nutrients, and electrical impulses that flow between the cells within every mycelium. These signals help keep the whole organism informed about happenings and coordinate actions across the network.
Research by Professor Andrew Adamatzky of the University of the West of England in Bristol analysed the electrical spikes generated by four species of fungi: enoki, split gill, ghost, and caterpillar fungi. He found that these spikes often clustered into trains of activity, resembling vocabularies of up to 50 "words". The distribution of these "fungal word lengths" closely matched those of human languages.
Fungi also communicate through pulsing behaviour, such as pulsing nutrient transport, which is possibly caused by rhythmic growth as fungi forage for food.
Additionally, mushrooms can gain new abilities through horizontal gene transfer. For example, three distantly related types of mushrooms gained the ability to produce a dangerous toxin through horizontal gene transfer from another, possibly extinct, mushroom. Horizontal gene transfer is the process by which a bacterium absorbs some of the genome of a host it is infecting and then passes those cells into another host.
