Their 1963 publication was the first report of psilocybin in a European mushroom species; previously, it had been known only in Psilocybe species native to Mexico, Asia and North America. The first reliably documented report of Psilocybe semilanceata intoxication involved a British family in 1799, who prepared a meal with mushrooms they had picked in London’s Green Park. When grown in dual culture with other saprobic fungi isolated from the rhizosphere of grasses from its habitat, P. semilanceata significantly suppresses their growth.
The stems and caps of psilocybin mushrooms can also be gently boiled in a tea to be sipped. Even though you won’t confuse fly agaric mushrooms (a species in the Amanita genus) with liberty cap mushrooms, it’s wise to be crystal clear on your identification. Protostropharia semiglobata is a dung-loving species (unlike P. semilanceata), with a shared preference for grazed grassland habitat, and a similar colored cap to a dry liberty cap. This colour-shifting can help you distinguish liberty caps from similar-shaped mushrooms. After a few hours, it was clear that many mushrooms live in the same grassland as liberty caps.
Panaeolus semiovatus, the egghead mottlegill, tends to be much larger (with a cap diameter of up to 6cm and a height of 15cm), does not have a pointed cap, and it bruises yellowish rather than bluish. Fortunately, these species are highly distinct from each other, differing markedly in both their appearances and habitat preferences. This mushroom is responsible for around 90% of mushroom-related deaths globally. The veil (skirt) leaves a fragile, white, often cobweb-like ring on the stem. The stem is fairly flexible; if applying light pressure it should spring back rather than snap in two.
The cap is hygrophanous, meaning it assumes different colors depending on its state of hydration. The cap of P. semilanceata is 5–25 mm (0.20–0.98 in) in diameter and 6–22 mm (0.24–0.87 in) tall. As they explained, conserving the name Psilocybe in this way would prevent nomenclatural changes to a well-known group of fungi, many species of which are “linked to archaeology, anthropology, religion, alternate life styles, forensic science, law enforcement, laws and regulation”. The species was first described by Elias Magnus Fries as Agaricus semilanceatus in his 1838 work Epicrisis Systematis Mycologici. The spores are dark purplish-brown en masse, ellipsoid in shape, and measure 10.5–15 by 6.5–8.5 μm. The gill attachment to the stipe is adnexed (narrowly attached), and they are initially cream-colored before tinting purple to black as the spores mature.
The stem is very slender and can be wavy, but its fibrous nature makes it quite strong unlike that of lookalikes. It is found in Tasmania and New Zealand, where it can be found growing from high-altitude grasslands to sea level. They grow abundantly in autumn and early winter in these locations. This is because it is in a large number of countries, with widespread distribution in Europe — where they are thought to be a native species. This species is more or less indistinguishable from Psilocybe pelliculosa. Click here to get on the waiting list for the first state-approved psilocybin therapy in the United States now!
According to Gartz (1995), P. semilanceata is Europe’s most popular psychoactive species. They concluded that the species was one of the most potent, as well as the most constant in psilocybin levels. In 1993, Gartz reported an average of 1% psilocybin (expressed as a percentage of the dry weight of the fruit bodies), ranging from a minimum of 0.2% to a maximum of 2.37% making it one of the most potent species (but significantly less potent than panaeolus cyanescens). Several studies published since then support the idea that the variability of psilocybin content in P. semilanceata is low, regardless of country of origin.
On the underside of the mushroom’s cap, there are between 15 and 27 individual narrow gills that are moderately crowded together, and they have a narrowly adnexed to almost free attachment to the stipe. In the 18th century, Phrygian caps were placed on Liberty poles, which resemble the stipe of the mushroom. Unlike P. cubensis, the fungus does not grow directly on dung; rather, it is a saprobic species that feeds off decaying grass roots. The mushrooms have a distinctive conical to bell-shaped cap, up to 2.5 cm (1 in) in diameter, with a small nipple-like protrusion on the top.
2 to 3mm in diameter and 4 to 10cm tall, the slender cream stem of Psilocybe semilanceata is fibrous, usually wavy and sometimes coloured blue towards the base. The olive-grey free gills turn purple-black as the spores mature. Ranging from 0.5 to 2cm in diameter, the cream-coloured caps have striations that become more pronounced with age and in dry weather.

These mushrooms’ positive benefits are plentiful, making them an exciting avenue to explore for those interested in natural remedies and ancient healing practices. The mycelial network functions as a sort of “wood wide web” and facilitates communication between mushrooms and other plants.
It takes .2 to .5 grams of dried magic mushrooms to begin to feel the effects of the psilocybin. It is nearly impossible to truly gauge the exact amount of psilocybin you are ingesting when munching on dried magic mushrooms or sipping on Liberty Cap-infused teas. It adores a liberty caps gills damp place to grow its delicate stems and caps. The accidental ingestion of psilocybin mushrooms can create lasting psychological effects. The caps come to a pointy head and are chartreuse to brown in coloring. The humble Liberty Cap (Psilocybe semilanceata) is one of the planet’s most potent psilocybin-containing mushroom species.
Some of the grassland bonnets (Mycena spp.) are similar in appearance and grow in the same grassland habitat and can look similar to liberty caps with age; however their striated cap clearly distinguishes them from P. semilanceata, along with their white spore print and fragile stem. Some of the mottlegills from the genus Panaeolus can look similar to liberty caps but they do not possess a pronounced umbo (a raised area or protrusion in the center of the mushroom cap) or the wavy, curving stem that liberty caps have (having straighter, stick-like stems). Let us now turn our attention to other mushrooms you may come across in the grassland habitat favored by liberty caps that may bear a resemblance to this species. I now turn to some similar-looking mushrooms that grow in the same grassland habitat as liberty caps.
The gills of both these species start off pale brown and turn to rust or cinnamon brown as in the third example. The cap is similar in colour to a dry liberty cap (not a wet one) The gills start off grey and turn to purplish-brown with age as spores get released.
The specific epitet semilanceata comes from semi- meaning ‘half’and -lanceata which means ‘spear-shaped’. Fairly frequent in Britain and Ireland, where it is rather localised, Psilocybe semilanceata occurs throughout Europe and is found also in North America. Psilocybe semilanceata, commonly known in the UK as the Magic Mushroom, and in the USA as Liberty Cap, appears in grassland in autumn. And with an understanding of the proper procedures and safety measures, one can indulge in these fascinating fungi without any legal or health risks. It may involve trampling delicate flora in pursuit of specific plant species, leading to soil degradation and damaging nearby wildlife populations. On the other hand, foraging can often lead to harmful practices where individuals take more than required without considering its impact on local ecosystems.
The Mexican mycologist (and Psilocybe authority) Gastón Guzmán wrote in his 1983 monograph on psilocybin mushrooms that liberty caps are the world’s most widespread psilocybin mushroom species. For obvious reasons, we are not encouraging you to pick or consume liberty cap mushrooms (psilocybe semilanceata). As potent psychedelic mushrooms, liberty cap mushrooms have the same psychoactive compounds as other magic mushrooms containing psilocybin and psilocin.
The cap dries from the top downwards, becoming light tan or yellow, or buff/white/gray/silver in color, occasionally with an olive tint, becoming more opaque, with the margin sometimes harboring darker bluish or olive stains, with dark gill lines only visible at the cap margin. When young it is typically translucent light brown to chestnut brown or caramel, remaining this color if the weather is wet, with a greasy shine and feel, with gill lines (or striations) visible beneath. Conocybe, Inocybe and Mycena all possess fragile flesh, and unlike P. semilanceata, it won’t be possible to peel a gelatinous membrane from the cap. While P. semilanceata will fruit in manure-rich grasslands, it will never be found fruiting directly from dung. However, around 2% of fungi species are considered truly poisonous globally, and might make you sick to varying degrees—anything from mild nausea to more serious, but non-fatal gastric disturbance.
This makes the stem more flexible than other mushrooms. A wet liberty cap will not be light, and a dry one will not be dark. For example, the liberty cap is famous for its nipple but this is not a unique feature. One danger of attempting to consume hallucinogenic or other wild mushrooms, especially for novice mushroom hunters, is the possibility of misidentification with toxic species. However this data has become obsolete over the years as more potent cultivars have been discovered for numerous species, especially panaeolus cyanescens which holds the current world record for most potent mushrooms described in published research. Smaller specimens tend to have the highest percent concentrations of psilocybin, but the absolute amount is highest in larger mushrooms.
Because of this, they can appear chestnut brown and dry to a light tan. But suppose you take the time to explore this mysterious landscape and learn what it has to offer. DoubleBlind is a trusted resource for news, evidence-based education, and reporting on psychedelics.
As the spores mature the gills turn a more purple or black color. Liberty cap mushrooms are not poisonous, and they are edible. The answer to both questions is no, unfortunately, although other psychedelic mushrooms can be found in Florida and elsewhere in the South. You can often find these mushrooms in pastures, where sheep and cow dung fertilize the soil. Liberty caps grow solitarily or in groups on rich and acidic soil, usually in grasslands, such as meadows, pastures, or lawns. There are some liberty cap lookalikes you should be aware of.
