The Institute of Microbiology of the Czech Academy of Sciences reports that over 6 million fungal species exist globally, with mushrooms being a significant portion. Their resemblance to toadstools often leads to confusion. Although their definitions are not strictly defined, understanding their general distinctions can help avoid potential health risks.
Distinguishing Mushrooms from Toadstools
Although toadstools and mushrooms share no biological distinctions, the term 'toadstool' is commonly associated with toxic fungi, while 'mushroom' usually refers to edible varieties. These definitions are not absolute, as there is no scientific method to clearly separate the two. The complexity increases with examples like the deadly death cap mushroom, known to cause kidney failure and fatal outcomes.

The Origins of Toadstool
The term toadstool has a somewhat unclear history, but there are theories about its origin. Some suggest it derives from toads, which were historically linked to toxins and disease, leading to the association with poisonous fungi. During the Middle Ages, fungi were also connected to witches and malevolent spirits, as they were responsible for unexplained deaths and illnesses.
Eating toxic mushrooms or toadstools can result in severe issues, including vomiting, diarrhea, hallucinations, liver failure, and even death. Since no home test can reliably identify poisonous fungi, it’s best to avoid foraging unless you’re highly skilled. Stick to purchasing mushrooms from trusted sources like grocery stores, farmers markets, or supermarkets.
For those confident in their foraging skills—or collaborating with an expert—consulting regional fungi guides or using mushroom identification apps can help locate safe, edible mushrooms in the wild.
