Wikipedia: Armillaria solidipes (formerly Armillaria ostoyae) is a species of fungus in the Physalacriaceae family. It is the most common variant in the western U.S., of the group of species that all used to share the name Armillaria mellea. Armillaria solidipes is quite common on both hardwood and conifer wood in forests west of the Cascade crest. The mycelium attacks the sapwood and is able to travel great distances under the bark or between trees in the form of black rhizomorphs ("shoestrings").
Here's where it gets heavy:It is known to be one of the largest living organisms, where scientists have estimated a single specimen found in Malheur National Forest in Oregon to have been growing for some 2,400 years, covering 3.4 square miles. Armillaria solidipes grows and spreads primarily underground and the bulk of the organism lies in the ground, out of sight. Therefore, the organism is not visible to anyone viewing from the surface. It is only in the autumn when this organism will bloom “honey mushrooms”, visible evidence of the organism lying beneath. Low competition for land and nutrients have allowed this organism to grow so huge and become arguably the largest living organism.
3.4 SQUARE MILES.
That's 8.9 SQUARE KILOMETRES.
That's 2,200 ACRES.
That's 94,786,560 SQUARE FEET.
Biologists estimate the weight of the colony to be somewhere in the neighborhood of 600 tons. That's the equivalent weight of three pregnant, adult blue whales, the world's largest known mammal.Is your brain okay?
Maybe you should cool down by watching this video--depicting an Armillaria mellea mycelium bioluminescence display in time-lapse (condensed from one week to 18 seconds)--on repeat for a little while:
