What does deathcup mean?
A deathcup is a colloquial name for a dangerously poisonous mushroom, applied chiefly to lethal members of the genus Amanita, including the notorious death cap (Amanita phalloides) and the destroying angels. The term also has a second, more technical sense: the delicate, cup-shaped wrapper — called a volva — left behind at the base of an Amanita's stalk when the young mushroom pushes up through its universal veil. For mushroom hunters, spotting this basal cup is one of the most important safety checks in the field, since it signals that a specimen could be an amanita and therefore potentially fatal if eaten. The word carries unmistakable connotations of danger and death, and it appears mainly in informal writing about foraging and natural history; scientists generally prefer exact species names. Knowing the term is genuinely useful, because it encapsulates both the identification feature and the life-or-death stakes of distinguishing edible fungi from their deadly look-alikes.

"He pulled up the whole clump, roots and all, and confirmed it was a deathcup."

The cup-shaped volva at the base of an Amanita's stalk, formed from the remains of the universal veil.
"A buried deathcup at the stem's base warned her the mushroom was an amanita."
Regular plural formation; used when referring to multiple specimens or multiple volvae.
"After the wet week, deathcups appeared across the oak woodland."
The deadliest mushrooms in the world carry their calling card underground — a ghostly 'cup' at the stem's base that mycologists call the deathcup.

Etymology of deathcup
The compound joins 'death', from Old English dēath, with 'cup', from Old English cuppe, itself borrowed from Latin cuppa, meaning a drinking vessel or tub. The name arose as folk terminology for deadly fungi, evoking the cup-shaped volva at the base of amanitas and, grimly, the fatal outcome of eating them. It belongs to the same family of vivid vernacular fungus names as 'destroying angel' and 'death cap', which similarly pair plain Anglo-Saxon roots with ominous imagery.
How deathcup is actually used
Informal and largely folk usage; in scientific and serious foraging contexts, writers prefer precise terms like 'Amanita phalloides' or 'death cap'. The word carries strong connotations of lethality and should never be used loosely about edible fungi.
Easily confused with deathcup
'Death cap' specifically names the single species Amanita phalloides, while 'deathcup' is a broader folk term that can refer to deadly amanitas generally or to the cup-shaped volva at the base of their stalks.
