The World's Largest Living Organism is a Fungus - Apparently.
The Armillaria ostoyae fungus, also known as the honey mushroom, covers over 2,200 acres in Oregon, USA. This vast fungal network is estimated to be around 2,400 years old, making it not only the largest living organism but also one of the oldest. The fungus grows by sending out underground tendrils that break down organic matter and absorb nutrients, allowing it to spread over such a vast area. Scientists have verified its age and size through DNA analysis and mapping.
