Fungi Signal Local Hydration Events

An experiment on Hebeloma mushrooms found that applying water to a single fruiting body boosts electrical communication across the mycelial network, whereas watering many mushrooms at once does not — suggesting fungal networks prioritize reporting localized changes. Short‑term urine sprinkling did not increase signaling in the three‑day study, likely because chemical breakdown to ammonia is slower at low temperatures. — If fungal networks preferentially broadcast local events, they could be harnessed or considered in ecosystem monitoring, trail management, and debates about how non‑animal organisms sense and coordinate across landscapes.
