The world’s largest known organism is a single honey fungus (Armillaria ostoyae) in Oregon’s Malheur National Forest, covering about 3.7 square miles with an extensive underground mycelial network and rhizomorphs. Genetic tests revealed it is a single clonal individual that killed trees by enzymatic decay, and estimates place its age between roughly 2,400 and 8,650 years.
The world’s biggest and oldest organism is a single clone of honey fungus (Armillaria ostoyae) in Oregon’s Malheur National Forest, spanning about 3.7 square miles. Its vast underground mycelial network (with rhizomorphs) grows by feeding on trees, while the surface shows bioluminescent hints known as foxfire. Estimates place its age between 2,400 and 8,650 years, underscoring how a fungus can dwarf all other life in scale.
The humongous fungus in Oregon, known as Armillaria ostoyae, is the largest organism on Earth by mass, spanning 2,385 acres and weighing around 35,000 tons, primarily existing as an underground network of mycelium that plays a crucial role in decomposing organic matter and recycling nutrients, with debates ongoing about its true size and the definition of an organism.
