The ink cap mushroom, or Coprinopsis atramentaria, is a powerful variety of fungus that has been known to burst through asphalt and lift paving stones. This mushroom is commonly found in grasslands, meadows, and disturbed ground, and is known for its ability to create acute sensitivity to alcohol, leading to symptoms such as facial reddening, nausea, and vomiting. The ink cap mushroom has a unique appearance, with a bell-shaped cap that splits at the margin and gills that change colour from white to grey or pinkish before turning black and dissolving into a thick, inky liquid. While the ink cap mushroom is considered edible when young, consuming it within a few hours of alcohol can result in severe disulfiram-like symptoms.

The ink cap mushroom's interaction with alcohol
The ink cap mushroom, scientifically known as Coprinopsis atramentaria, has a unique interaction with alcohol. This species of mushroom, commonly found in the Northern Hemisphere, is known to cause acute sensitivity to alcohol, a condition sometimes referred to as "Tippler's Bane". Consuming alcohol within a few hours of ingesting these mushrooms can lead to a range of unpleasant symptoms, including facial reddening, nausea, vomiting, malaise, agitation, palpitations, and tingling in the limbs. These symptoms can arise within five to ten minutes of consuming alcohol and can last for up to three hours. The severity of the symptoms is directly related to the amount of alcohol consumed.
The active compound responsible for this interaction is called coprine, a mycotoxin found in the ink cap mushroom. Coprine inhibits the activity of an enzyme called acetaldehyde dehydrogenase, which is crucial for breaking down acetaldehyde, a toxic byproduct of alcohol metabolism. When this enzyme is blocked, acetaldehyde accumulates in the body, leading to the characteristic symptoms of "Coprinus syndrome" or coprine poisoning. Interestingly, the ink cap mushroom has been considered in the past for treating alcoholism due to these effects, similar to the drug disulfiram (Antabuse) which also inhibits aldehyde dehydrogenase.
It is important to note that the interaction between ink cap mushrooms and alcohol can have severe consequences. Consuming alcohol even up to three days after eating these mushrooms can still lead to symptoms, although they tend to be milder with the passage of time. In rare cases, more serious complications such as cardiac arrhythmias may occur. Therefore, it is strongly advised to refrain from consuming alcohol for several days before and after ingesting ink cap mushrooms.
The ink cap mushroom derives its name from the black liquid it releases when picked, which was historically used as ink. This mushroom is widespread and can be found in urban areas, grasslands, meadows, disturbed ground, and open terrain. While the ink cap mushroom is considered edible when young, it is crucial to be aware of its potential toxicity when combined with alcohol.

The ink cap mushroom's physical characteristics
The ink cap mushroom, scientifically known as Coprinopsis atramentaria, has several distinctive physical characteristics. Firstly, it typically grows in tufts or small clumps, often associated with buried wood of deciduous hardwood trees. It is commonly found in grasslands, meadows, disturbed ground, and urban areas from late spring to early winter.
The mushroom's cap is initially bell-shaped and greyish or brownish-grey with a furrowed texture. As it matures, the cap becomes more convex and splits at the margin, eventually turning black. The cap measures 3-10 centimetres in diameter and is surrounded by very crowded gills that are white at first, then turn grey or pinkish, and finally black.
The stipe or stem of the ink cap mushroom is hollow and white, with reddish-brown fibres called fibrils. It is 5-17 centimetres high and 1-2 centimetres thick, lacking a ring. In young mushrooms, the stems may be obscured by the caps.
The spores of the ink cap mushroom are elliptical or almond-shaped and produce a black spore print. The flesh of the mushroom is thin and pale grey. When the mushroom is mature, its gills autodigest, releasing a black liquid that was historically used as ink. This process of autodigestion is unique to the ink cap mushroom and is an important characteristic that distinguishes it from other mushrooms.

The ink cap mushroom's lifecycle
The ink cap mushroom, scientifically known as Coprinopsis atramentaria, undergoes various stages in its lifecycle, from growth to deterioration. Here is a detailed overview of the ink cap mushroom's lifecycle:
Spore Formation
The lifecycle of the ink cap mushroom begins with spore formation. The mature gills of the mushroom produce spores, which are elliptical and black in colour. These spores are microscopic and are released into the surrounding environment.
Germination
When the spores encounter suitable conditions, they germinate and develop into thread-like structures called hyphae. These hyphae grow and intertwine to form a network called mycelium, which is the vegetative part of the fungus. The mycelium can remain dormant underground for years, waiting for the right conditions to fruit.
Fruiting and Growth
When environmental conditions are favourable, typically in spring or early winter, the mycelium produces fruiting bodies. The ink cap mushrooms grow in tufts or small clumps, often associated with buried wood of deciduous hardwood trees. They can be found in grasslands, meadows, disturbed ground, and even urban areas like vacant lots or tennis courts.
The young mushrooms have bell-shaped caps that are greyish or brownish-grey and measure 3-10 centimetres in diameter. The gills underneath the cap are initially white, but they gradually change colour as the mushroom matures.
Maturity and Deliquescence
As the ink cap mushroom matures, its gills turn from white to grey or pinkish and eventually to black. At this stage, the gills begin to autodigest, releasing a thick, inky black liquid that drips from the edges of the cap. This liquid was historically used as ink, giving the mushroom its name.
Deterioration
After releasing their spores and deliquescing, the ink cap mushrooms start to deteriorate. They melt from the outside in, and their caps split further at the margins. The mushrooms continue to degrade even after being picked, so they must be consumed soon after picking if they are to be eaten.

The ink cap mushroom's toxicity
Ink cap mushrooms, scientifically known as Coprinopsis atramentaria, are considered edible when young. However, they become poisonous when consumed with alcohol. The mushrooms contain a cyclopropylglutamine compound called coprine, which blocks the action of the enzyme acetaldehyde dehydrogenase, responsible for breaking down acetaldehyde, a byproduct of alcohol metabolism. This inhibition results in a buildup of acetaldehyde in the body, leading to severe poisoning.
The interaction between ink cap mushrooms and alcohol consumption can lead to disulfiram-like symptoms, including facial reddening, nausea, vomiting, malaise, agitation, palpitations, and tingling in the limbs. These symptoms can arise within five to ten minutes of consuming alcohol and typically subside within two to three hours if no additional alcohol is ingested. The severity of symptoms is directly proportional to the amount of alcohol consumed. They become evident when blood alcohol concentration reaches 5 mg/dl and become prominent at concentrations of 50–100 mg/dl.
It is important to note that the toxic effects of consuming ink cap mushrooms with alcohol can occur even if alcohol is consumed up to three days after eating the mushrooms. However, the symptoms tend to be milder as more time passes. In rare cases, consuming ink cap mushrooms with alcohol can lead to cardiac arrhythmia, such as atrial fibrillation on top of supraventricular tachycardia, or even myocardial infarction (heart attack). Due to these potential severe consequences, it is strongly advised not to consume ink cap mushrooms if alcohol has been consumed during the three days before or after.
Historically, the ink cap mushroom has had various uses. As its name suggests, the black liquid released by the mushroom was once used as ink. Notably, this ink was used for important documents as the presence of spores could be detected under a microscope, thus guarding against forgery. Additionally, due to its ability to create acute sensitivity to alcohol, similar to disulfiram (Antabuse), the ink cap mushroom has been used in some cases to treat alcoholism.

The ink cap mushroom's history of use as ink
The ink cap mushroom, scientifically known as Coprinopsis atramentaria, has a long history of use as ink. First described scientifically in 1786 by the French botanist and mycologist Jean Baptiste Francois Pierre Bulliard, the common ink cap was given the name Agaricus atramentarius. The name "atramentarius" is derived from the Latin word "atramentum," which refers to a very dark or black substance, particularly a liquid such as ink.
True to its name, the common ink cap mushroom releases a black liquid when picked. This liquid has been used as ink throughout history, particularly for important documents. The use of this natural ink had an advantage: it guarded against forgery as the unique spores of the mushroom could be detected under a microscope.
The common ink cap is widespread in the UK and is often found in pastures, parks, gardens, tree stumps, and even pavements, wherever there is buried wood. It usually appears in clusters but can also be found as solitary specimens. The mushroom is powerful, with the ability to burst through asphalt and lift paving stones due to the immense strength of the vertically aligned hyphae in its stems.
Historically, the common ink cap has been given various names depending on the time and location. In America, the terms "Inky Cap" or "Inky-cap" are prevalent, while older field guides in Britain often refer to it as "Ink Cap" or "Ink-cap." Despite its toxic effects when consumed with alcohol, the common ink cap mushroom has left its mark on history as a natural source of ink, with its very name reflecting this unique characteristic.
