Mushrooms Communicate With Each Other Using Up To 50 'Words', Scientist Claims

An anonymous reader quotes a report from the Guardian: Buried in forest litter or sprouting from trees, fungi might give the impression of being silent and relatively self-contained organisms, but a new study suggests they may be champignon communicators. Mathematical analysis of the electrical signals fungi seemingly send to one another has identified patterns that bear a striking structural similarity to human speech. Previous research has suggested that fungi conduct electrical impulses through long, underground filamentous structures called hyphae -- similar to how nerve cells transmit information in humans. It has even shown that 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 with distant parts of themselves, or with hyphae-connected partners such as trees. But do these trains of electrical activity have anything in common with human language?

To investigate, Prof Andrew Adamatzky at the University of the West of England's unconventional computing laboratory in Bristol analyzed the patterns of electrical spikes generated by four species of fungi -- enoki, split gill, ghost and caterpillar fungi. He did this by inserting tiny microelectrodes into substrates colonized by their patchwork of hyphae threads, their mycelia. The research, published in Royal Society Open Science, found that these spikes often clustered into trains of activity, resembling vocabularies of up to 50 words, and that the distribution of these "fungal word lengths" closely matched those of human languages.
