World's largest organism? Probably not. Not this one, anyway.

These mushrooms are the fruiting body of a fungus known as Armillaria. The mushrooms are known to foragers as "honey mushrooms." For a brief while there was a hullabaloo about a fungus being the world's largest organism. But it's probably not really. This is the same kind of fungus. It parasitizes tree roots, killing trees and feeding on the dead wood. A huge dead maple or ash blew over at the santuary last week; I found an old cluster of honey mushrooms at the base of the stump.
