The story of the word

Coined in the 1830s for what a fungus actually is, the mushroom being only its fruiting body. The first element is μύκης, fungus; the second is unsettled, with ἧλος, nail or wart, the usual guess and not a confident one. One mycelium of Armillaria in Oregon's Malheur National Forest spreads across roughly nine square kilometres, which makes the honey mushrooms above it a rounding error.
