the.com/honey fungus

the largest living organism on Earth, quietly murdering forests one root at a time

means A parasitic fungus of the genus Armillaria that infects and kills trees by spreading through soil and roots, often producing clusters of honey-colored mushrooms above ground.

from The name simply describes the mushroom's warm, honey-brown caps — "honey" from Old English hunig, "fungus" straight from the Latin word for mushroom or sponge. A plain, almost cozy label for an organism whose root-creeping black threads, called rhizomorphs or "bootlaces," can stretch for miles underground; one specimen in Oregon's Blue Mountains sprawls across thousands of acres, which is how this honey-named killer earns its title as the largest known living thing.
