The terms mushroom and toadstool are often used interchangeably, but there is no scientific distinction between the two. Toadstools are sometimes used to refer to colourful and poisonous or inedible mushrooms, but this is not a scientifically accepted distinction. Mushrooms and toadstools are both the spore-bearing fruiting bodies of fungi, typically taking the form of a domed or rounded cap on a stalk. While mushrooms are often considered edible, and toadstools toxic, this is not always the case, and it can be dangerous to assume that a fungus is safe to eat based solely on its appearance.

What You'll Learn
Toadstools are often poisonous mushrooms
In common speech, people tend to use the word "toadstool" to refer to fungi that are toxic, poisonous, or simply inedible. The word "mushroom" is used to describe tasty and edible mushrooms. However, this is not a hard-and-fast rule, and some toadstools are edible. The delineation between edible and poisonous fungi is not clear-cut, so a "mushroom" may be edible, poisonous, or unpalatable.
Toadstools and mushrooms cannot be distinguished by shape, colour, or appearance. Both are the spore-bearing fruiting bodies of fungi, typically in the form of a domed or rounded cap on a stalk. The gills of a mushroom are attached to the cap and not to the stalk, so when the stalk is removed from its base, the gills stay attached to the cap. If the gills stay attached to the stalk, it is not a true mushroom. The gills of a true mushroom are also not white throughout their entire life cycle, unlike those of toadstools. The cap of a true mushroom pulls away from the stem as it grows, leaving a ring of tissue around the stem. If there is no ring of tissue, it is not a true mushroom.
It is important to be able to distinguish between edible and poisonous mushrooms, especially when foraging. Molecular classification is the best way to distinguish between the two, but this requires expensive equipment that most foragers do not carry.

Mushrooms are typically edible
The terms "mushroom" and "toadstool" are often used interchangeably, but there is no scientific difference between them. Toadstools are typically used to refer to inedible or poisonous mushrooms. However, this is not a reliable method of distinguishing between edible and poisonous mushrooms. Some toadstools are edible, and some mushrooms are poisonous.
There are thousands of different types of mushrooms and toadstools, and it can be challenging to distinguish between them. Some sources suggest that true mushrooms have smooth, white caps with no raised scales or warts, while toadstools have coloured caps with scales and raised lumps. However, this is not always the case, as some poisonous mushrooms, such as the death cap, have white caps.
To determine whether a mushroom is edible, it is essential to consider various characteristics, including colour, size, pores, gills, spore colour, flesh colour, habitat, smell, and taste. Molecular classification is the most accurate method, but it requires expensive equipment that most foragers do not carry. Therefore, it is crucial to have a basic understanding of the macroscopic structure of mushrooms and toadstools and to exercise caution when consuming wild mushrooms.

Toadstools are believed to be inedible
The belief that toadstools are inedible may be due to their appearance, as they are often considered more unique-looking or colourful than mushrooms. In parts of Europe, people refer to mushrooms as fungi that typically grow in fields and are pink or white in colour, while toadstools are more colourful species that grow in the woods. Toadstools also tend to grow under trees or shrubs, while mushrooms are usually found in open spaces.
However, it is important to note that the delineation between edible and poisonous fungi is not clear-cut, and there is no single trait by which all toxic or edible mushrooms can be identified. While some characteristics, such as the colour of the gills and the shape of the cap, can provide clues about whether a fungus is edible, molecular classification is the most accurate way to distinguish edible mushrooms from toxic toadstools.
Furthermore, the term "toadstool" is quite subjective and loose, and there is no biological distinction between a toadstool and a mushroom. It is simply an unscientific label applied to certain types of mushrooms, and toadstools can be considered a type of mushroom. Therefore, while toadstools are generally believed to be inedible, it is essential to use careful identification methods to determine whether a particular fungus is safe to consume.

Mushrooms are usually white
The terms "mushroom" and "toadstool" are often used interchangeably, but there is no scientific distinction between them. Toadstools are sometimes used to refer to colourful and poisonous or inedible mushrooms. However, there is no single trait by which all toxic or edible mushrooms can be identified. Mushrooms and toadstools are both the spore-bearing fruiting bodies of fungi, typically with a domed cap on a stalk. The gills of a mushroom are attached to the cap, not the stalk, and the gills of a true mushroom turn pink as it matures and eventually brown to black. The gills of toadstools remain white throughout their life cycle.
The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus. Hence, the word "mushroom" is most often applied to those fungi that have a stem, a cap, and gills on the underside of the cap. The cap of a true mushroom is smooth and white, while toadstools often have a differently coloured cap with scales and raised lumps. The upper part of a mushroom, or the cap, is usually white with no conspicuous raised scales or warts. The colour of the powdery print, or spore print, varies and includes white, brown, black, purple-brown, pink, yellow, and creamy shades. However, it is almost never blue, green, or red.
Mushrooms are typically found growing in open spaces, such as fields or lawns, while toadstools are often found under trees or shrubs. In parts of Europe, people refer to mushrooms as fungi that typically grow in fields and are pink or white in colour. In contrast, toadstools are considered more colourful species that grow in the woods.
While the word mushroom is used to describe tasty and edible mushrooms, the term toadstool is used to refer to inedible or poisonous varieties. However, this distinction is not always clear-cut, and some toadstools may be edible. For example, the death cap is white and resembles a traditional mushroom, but it is one of the most poisonous varieties of fungi. Therefore, it is important to identify the specific characteristics of a mushroom before consumption, as mistaking a toadstool for a mushroom can have dangerous consequences.

Toadstools are often colourful
The term "toadstool" is often used to refer to colourful and poisonous or inedible mushrooms. While there is no scientific distinction between toadstools and mushrooms, toadstools are typically believed to be inedible or toxic. They are often distinguished by their colourful caps, which may have scales and raised lumps. For example, the dangerous fly agaric (Amanita muscaria) is a toadstool with a red cap and white spots. In parts of Europe, toadstools are considered to be the colourful species that grow in the woods, while mushrooms are the pink or white fungi that grow in fields.
The word "toadstool" first appeared in 14th-century England, referring to a ""stool" for toads, implying an inedible poisonous fungus. This association with poison has carried over into modern terminology. Toadstools are often believed to be toxic mushrooms with distinctive appearances. For example, the death cap is white and resembles a traditional mushroom, but it is one of the most poisonous varieties of fungi.
The terms "mushroom" and "toadstool" are used interchangeably by some, and there is no single trait that distinguishes toxic from edible mushrooms. Mushrooms are typically considered to be the white-capped species that grow in fields and are safe to eat. However, some poisonous mushrooms, like the death cap, also have white caps. Therefore, it is important to identify mushrooms based on multiple criteria, including colour, size, pores, gills, spore colour, flesh colour, habitat, smell, and more.
While toadstools are generally associated with poisonous or inedible mushrooms, not all toadstools are poisonous, and some mushrooms that are considered "true mushrooms" can also be toxic. Therefore, it is essential to properly identify any mushrooms before consuming them.
