The Humongous Fungus was discovered in 1992 by a local forester investigating the death of a stand of white pine trees. The fungus was found to be the cause of the tree’s death, and it was soon determined to be one of the largest living organisms on Earth. The fungus is a pathogen that infects and kills trees and is thought to have spread from a single tree for centuries.

The Humongous Fungus is a popular tourist destination, and it is estimated that the festival attracts over 10,000 visitors each year. The festival is a great way to learn about the fungus and its importance to the local ecosystem.
