horse mushroom
C1/C2Specialist/Informal
Definition
Meaning
A large, edible, wild mushroom (Agaricus arvensis) often found in grassland, particularly where horses graze.
A common name for a mushroom species in the genus Agaricus, closely related to the common button mushroom, characterized by its large size, smooth cap that yellows with age, and anise-like scent.
Linguistics
Semantic Notes
The name is derived from its frequent occurrence in horse pastures and meadows, not because horses eat it. It is a compound noun where 'horse' acts as an intensifier, often indicating largeness or coarseness (e.g., 'horse chestnut').
