As a pedantic, mushroom-hating former scientist, it drives me crazy when some restaurant has a “mixed vegetables”dish that contains mushrooms.
This is like referring to group of “motor vehicles” and meaning it to contain some cars and running shoes. SHOES ! ! !
Not only are they not motorized, they’re not a vehicle!
Mushrooms are not only not a vegetable, they’re not even a member of the same life kingdom (plants vs. fungi, for anyone with a base understanding of biology). They’re no more a plant than is a bacteria or an insect. The only similarity between vegetables and mushrooms is that they’re both [theoretically] edible, like how motor vehicles and running shoes are both [loosely] enablers of transportation.
