The largest living organism, once considered to be the blue whale, might not be what you expect. The discovery of a giant fungus in Oregon has claimed the prize.

The discovery of this giant Armillaria ostoyae in 1998 heralded a new record holder for the title of the world’s largest known organism, believed by most to be the 110-foot- (33.5-meter-) long, 200-ton blue whale. Based on its current growth rate, the fungus is estimated to be 2,400 years old but could be as ancient as 8,650 years, which would earn it a place among the oldest living organisms as well.
A team of forestry scientists discovered the giant after setting out to map the population of this pathogenic fungus in eastern Oregon. The team paired fungal samples in petri dishes to see if they fused (see photo below), a sign that they were from the same genetic individual, and used DNA fingerprinting to determine where one individual fungus ended.
