I think that most people, in the English-speaking world at least, have heard the word "toadstool" and have probably used it too to describe some form of mushroom. In fact, I would be curious to know whether other languages have a similar expression.
From my knowledge of its usage in English it is generally used to describe an inedible type of fungus found in the forest.
I cannot recall every having seen it as a toadstool literally, until I came across this American Toad Anaxyrus americanus resting on bracket fungi.
The forest was full of toads, with many tiny ones, but this full grown specimen was the pride of the bunch. It was very co-operative as it posed for pictures, even turning to give us a different view, without leaving its seat.
Nature is wonderful! Every day's exploration holds a potential surprise; I wonder what my next new discovery will be?
