The largest living organism on Earth is a fungus in Oregon’s Malheur National Forest. Covering over 3.5 square miles underground, this Armillaria fungus has been growing for thousands of years. Most of it is hidden beneath the soil, with only occasional mushrooms appearing above ground.
This enormous organism highlights how life can thrive in unexpected ways. Studying such fungi helps scientists understand growth, longevity, and ecological impact, showing that size and influence in nature are not always visible on the surface. Shutdown123
