That fungi could use electrical signaling as a basis for rapid communication has not been lost on Andrew Adamatzky, the director of the Unconventional Computing Laboratory. In 2018, he inserted electrodes into whole oyster mushrooms sprouting in clusters from blocks of mycelium and detected spontaneous waves of electrical activity. When he held a flame up to a mushroom, different mushrooms within the cluster responded with a sharp electrical spike. Shortly afterward, he published a paper called “Towards fungal computer.” In it, he proposed that mycelial networks “compute” information encoded
