Toadstools are a type of poisonous mushroom
Toadstools are a type of mushroom, but the term is often used to refer to poisonous fungi. Scientifically, there is no distinction between a toadstool and a mushroom, and toadstools are not a distinct group of fungi. However, in casual speech, people tend to use the word "toadstool" to refer to toxic, poisonous, or inedible fungi, while the word "mushroom" is used for edible varieties. The word "toadstool" first appeared in 14th-century England, possibly referring to a "stool" for toads and implying an inedible, poisonous fungus.
While some toadstools are indeed poisonous, not all fit this description. For example, porcini, wine caps, and morels resemble toadstools but are edible and tasty. Conversely, some mushrooms that look like edible varieties can be poisonous, such as young Amanita mushrooms, which can look like puffballs or button mushrooms. Therefore, it is essential to correctly identify any wild fungi before consuming them, as some poisonous mushrooms can be challenging to distinguish from edible species.
The terms "mushroom" and "toadstool" are used to describe the fleshy fruiting bodies of certain types of fungi. The standard for the name "mushroom" is the cultivated white button mushroom (Agaricus bisporus), which has a stem (stipe), a cap (pileus), and gills (lamellae) on the underside of the cap. "Mushroom" also describes other gilled fungi, with or without stems, and some non-gilled varieties. Forms that deviate from this standard morphology often have more specific names, such as "bolete", "truffle", "puffball", "stinkhorn", and "morel".
Identifying mushrooms requires an understanding of their macroscopic structure, including features such as color, shape, size, stem color, the presence of a ring or volva, warts, smell, taste, and other characteristics. The context in which the mushrooms are found, such as the season, habitat, and growth medium, is also essential for identification. Modern identification methods are increasingly based on molecular analysis, but traditional approaches, including microscopic examination and field guides, are still commonly used.

Mushrooms and toadstools are both types of fungi
Mushrooms and toadstools are not distinct taxonomic groups of fungi. Instead, the terms are used interchangeably, depending on the region and local language. The word "mushroom" is loosely used to describe various gilled and non-gilled fungi, making it challenging to provide a precise taxonomic definition. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus, which has a stem, a cap, and gills. However, the term also encompasses other gilled fungi, such as boletes, puffballs, and stinkhorns.
Toadstools, on the other hand, are often associated with poisonous mushrooms. Terms like "devil's droppings" and "wart caps" were once used to describe poisonous mushrooms but have fallen out of modern usage. While some toadstools are indeed poisonous, not all fit the traditional description. For example, porcini, wine caps, and morels are unique-looking mushrooms that might be mistaken for toxic toadstools, yet they are edible and savoured for their taste.
Identifying whether a fungus is a mushroom or a toadstool is not always straightforward. It requires knowledge of their macroscopic structure, including characteristics such as colour, shape, size, stem colour, the presence of a ring or volva, warts, smell, taste, and other features. Additionally, contextual factors like season, habitat, and growth medium play a role in identification. Amateur and professional mycologists employ standard methods, microscopic examination, and molecular techniques for accurate identification.

Toadstools are often brightly coloured
Toadstools are often associated with poisonous or inedible mushrooms. The word "toadstool" is believed to have first appeared in 14th-century England, referring to a "stool" for toads, and implying that toadstools are inedible or poisonous. This association persists in modern terminology. Toadstools are often brightly coloured, and while this does not always indicate toxicity, it is a key indicator used by mushroom hunters to identify and avoid poisonous fungi. Other factors considered include the colour of spores, shape, size, stem colour, the presence of a ring or volva, warts, smell, taste, season, habitat, and growth medium.
The delineation between edible and poisonous fungi is not always clear-cut, and some toadstools that appear poisonous may be edible and tasty. For example, porcini, wine caps, and morels are colourful and unique-looking mushrooms that resemble toxic toadstools but are edible. Conversely, some edible mushrooms may be unsafe to eat due to potential poisons and allergens. Young amanita mushrooms, for instance, can look like edible puffballs or button mushrooms but are poisonous.
The terms "mushroom" and "toadstool" are culturally and contextually dependent. In some countries, mushrooms that need to be prepared or parboiled before eating are considered inedible or poisonous. Additionally, the language used to refer to different types of mushrooms varies across the world. While the standard for the name "mushroom" is the cultivated white button mushroom, the term is also loosely used for various gilled and non-gilled fungi.
Toadstools and mushrooms are types of fungi that obtain nutrients from decaying organic matter and aim to release their spores to reproduce. Both are most likely to appear in the autumn months. While there is no scientific distinction between toadstools and mushrooms, people tend to use the term "toadstool" for toxic, poisonous, or inedible fungi and "mushroom" for edible ones. However, this distinction is not always accurate, and proper identification of edible mushrooms is crucial to avoid health risks.

Mushrooms usually have a stem, cap and gills
Toadstool is a term that can be used interchangeably with mushrooms in casual speech. Scientifically, there is no distinction between a toadstool and a mushroom. However, in common parlance, toadstools often refer to toxic, poisonous, or inedible mushrooms. Conversely, mushrooms typically refer to edible fungi. The terms used to describe these fungi vary across different regions.
Mushrooms typically have a stem, cap, and gills. The cap, or pileus, sits atop the mushroom and holds the gills or pores. Caps can differ in shape, size, colour, and texture, ranging from smooth to scaly. The shape of the cap can be useful in identifying the species of a mushroom. For example, the caps of mushrooms in the Kuehneromyces genus are typically convex to bell-shaped, while those in the Pholiota genus are often dry and covered in scales or fibres.
Gills are found on the underside of the cap and can be attached to the stem or free, not reaching the stem. They can have various forking or branching patterns, and their lengths can vary from very short to long. True gills are separate parts of a mushroom that can be picked off, while false gills appear as smooth ridges underneath the cap. For instance, the structures on chanterelle mushrooms resemble forked gills but are actually false gills.
The colour of the gills can also vary. For instance, the gills of the Phylloporus species are bright yellow and bruise blue-green, while the gills of the Lentinus and Neolentinus species have a leathery texture. Additionally, the gills of the Lactarius s.l. and Russula species snap like chalk, and the gills of the Cystoderma, Cystolepiota, and Leucocoprinus species have a granular coating that may disappear as the mushroom ages.
Some mushrooms may have teeth or spines instead of gills. These structures, also known as spines, hang from the underside of the cap or grow from the stem. Examples include the lion's mane mushroom, which has teeth, and the coral tooth mushroom, which has icicle-like spines.

Toadstools are believed to be referenced in fairy tales
The term "toadstool" is believed to have originated sometime between 1400 and 1600 AD, coinciding with the evolution of the word "mushroom". It is widely speculated that the term "toadstool" is a reference to fairy tales and folk tales featuring toads sitting on top of mushrooms.
Toadstools, in the context of fairy tales, are often associated with magical and fantastical elements. They are described as the dwellings of fairies, gnomes, and elves, contributing to the whimsical nature of these stories. Toadstools, with their distinctive appearance, have become a symbol of fairyland and enchanting realms.
In literature, toadstools are often depicted as shelters, providing refuge from the rain or harsh weather. They are also associated with the mysterious and enchanting, as they appear and disappear, adding an element of intrigue to the stories. Toadstools are described as having various shapes, from "high, Peak'd, like half-shut parasols" to "round and low, like balls, little hollow balls."
The Amanita muscaria, commonly known as the fly agaric, is the toadstool most frequently associated with fairy tales. It is characterised by its red (or occasionally orange) cap with white gills and white flakes. This particular toadstool is not just visually striking but also contains hallucinogenic chemicals and neurotoxins, further contributing to its allure and association with magical realms.
While the term "toadstool" is often used casually to refer to poisonous or inedible mushrooms, it is important to note that the distinction between mushrooms and toadstools is not scientifically based. The difference lies primarily in common speech and cultural context, with "toadstool" often carrying a negative connotation.
