What does toadstool mean?
A toadstool is a mushroom, especially one regarded as poisonous or otherwise unsuitable for eating. In everyday British and American English, the word often carries a slightly alarming or humorous association with toxic fungi, even when a speaker has a particular species in mind; dictionaries and field guides may nevertheless use it broadly for mushrooms of many kinds. The word can therefore sound less neutral than mushroom, which describes both cultivated edible varieties and wild fungi. In literary or figurative use, toadstools can evoke bizarre shapes, lurid colors, fairy tales, and the strangeness of fungi growing in dark or secluded places. Toadstool is a closed compound formed from toad and stool, with the name referring to a toad-like shape or appearance. The term remains useful when the important contrast is between a familiar mushroom and a wild, possibly poisonous fungus. Its vivid imagery makes it memorable, while the identification of a particular species remains a matter for a field guide rather than the word itself.

The regular plural is used for individual mushrooms and, sometimes, for multiple kinds of mushroom.

The name joins two ordinary words, “toad” and “stool,” because some mushrooms resemble squat, spotted toads.
