The World's Largest Living Organism Is a Fungus in Oregon
In the Malheur National Forest, Oregon, a single Armillaria ostoyae (honey fungus) spreads across 965 hectares (2,385 acres) — roughly 1,350 football fields. Estimated to be about 8,000 years old, it grows mostly underground as mycelium. Discovered in 1998, it broke the previous record held by a similar fungus in Michigan.
