Mushroom hunting, mushrooming, mushroom picking, mushroom foraging, and similar terms describe the activity of gathering mushrooms in the wild, typically for culinary use. This practice is popular throughout most of Europe, Australia, Japan, Korea, parts of the Middle East, and the Indian subcontinent, as well as the temperate regions of Canada and the United States.

Morphological characteristics of the caps of mushroom, such as those illustrated in the above chart, are essential for correct visual mushroom identification.

Numerous field guides on mushrooms are available and recommended to help distinguish safe, edible mushrooms from the many poisonous or inedible species.

A spore print is a mushroom identification technique commonly used by mycologists and mushroom hunters to help identify the genus of a specimen and differentiate between similar looking species.

Knowing where and when to search for mushrooms is an important identification skill that takes practice. Most mushroom species require specific conditions. For example, some species only grow at the base of a certain type of tree. Finding a desired species that is known to grow in a certain region can be a challenge.

Mushroom hunting can be associated with significant health risks if it is done without caution since many mushrooms that are safe for consumption have lethally poisonous lookalikes. Even if consuming a poisonous mushroom does not result in death, some can still cause permanent organ damage.[1] Mushroom poisoning kills an average of seven people every year in the United States alone and sickens thousands more.[2]

Many mushroom guidebooks call attention to similarities between species, especially significant if an edible species is similar to, or commonly confused with, one that is potentially harmful.

Examples:

Little brown mushrooms

Inocybe lacera is a typical 'little brown mushroom', and is easily identifiable only by distinctive microscopic features.
Inocybe lacera is a typical 'little brown mushroom', and is easily identifiable only by distinctive microscopic features.

"Little brown mushrooms" (or LBMs) refers to a large number of small, dull-coloured agaric species, with few uniquely distinguishing macromorphological characteristics.[4][5] As a result, LBMs typically range from difficult to impossible for mushroom hunters to identify. Experienced mushroom hunters may discern more subtle identifying traits that help narrow the mushroom down to a particular genus or group of species, but exact identification of LBMs often requires close examination of microscopic characteristics plus a certain degree of familiarity or specialization in that particular group.

For mycologists, LBMs are the equivalent of LBJs ("little brown jobs")[6] and DYCs ("damned yellow composites") that are the bane of ornithologists and botanists, respectively.

"Big white mushroom" (or BWM) is also sometimes used to describe groups of difficult to identify larger and paler agarics, many of which are in the genus Clitocybe.

Psychotropics

The Amanita muscaria's psychotropic properties have been traditionally used by shamans in Siberia in their rituals. However, its use for such purposes is very rare today, despite the mushroom's abundance and in part because of its severe side effects.

The Psilocybe semilanceata is more sought after for its hallucinogenic properties. It is more popular for recreational use than A. muscaria due to its reduced side effects. The use of P. semilanceata may be hindered by its small size, requiring larger quantities to take effect and being hard to spot.

Other Psilocybe species are abundant in the American south and west, as well as Mexico, where they have been used by traditional shamans for centuries. In the west, mushroom pickers may frequent cow pastures looking for psilocybes. This can be dangerous, as many species can grow in pastures and amateurs often misidentify psilocybes.

Consumption of poisonous species

There are treatments to reduce or eliminate the toxicity of certain (but not all) poisonous species to the point where they may be edible.[7] For instance, false morels are deadly when eaten raw or incorrectly prepared, but their toxins can be reduced by a proper method of parboiling. Prepared in this way, this mushroom is widely used and considered a delicacy in many European countries, although recent research suggests that there may still be long-term health consequences from eating it.[8]

Festivals

The popularity of mushroom picking in some parts of the world has led to mushroom festivals. The festivals are usually between September and October, depending on the mushrooms available in a particular region. Festivals in North America include:

Radiation

Nuclear fallout from the Chernobyl disaster is an important issue concerning mushroom picking in Europe. Due to the wide spread of their mycelium, mushrooms tend to accumulate more radioactive caesium-137 than surrounding soil and other organisms. State agencies (e.g. Bellesrad in Belarus) monitor and analyze the degree of radionuclide accumulation in various wild species of plants and animals. In particular, Bellesrad claims that Svinushka (Paxillus ssp.), Maslenok (Suillus ssp.), Mokhovik (Xerocomus ssp.), and Horkushka (Lactarius rufus) are the worst ones in this respect. The safest one is Opyonok Osyenniy (Armillaria mellea). This is an issue not only in Poland, Belarus, Ukraine and Russia: the fallout also reached western Europe, and until recently the German government discouraged people gathering certain mushrooms.[citation needed]

The situation is treated with black humor in some Russian jokes.[citation needed]

Commonly gathered mushrooms

A large number of mushroom species are favored for eating by mushroom hunters. The king bolete is a popular delicacy. Sulphur shelf (also known as "chicken mushroom" and "chicken of the woods") is often gathered because it occurs in bulk, recurs year after year, is easily identified, and has a wide variety of culinary uses. Pine mushrooms, chanterelles, morels, oyster mushrooms, puffballs and polypores are among the most popular types of mushrooms to gather, most of these being fairly simple to properly identify by anyone with practice. Much more care, education, and experience is typically required to make a positive identification of many species, however, and as such, few collect from more dangerous groups, such as Amanita, which include some of the most toxic mushrooms in existence.

Commonly gathered species, grouped by their order taxa, are as follows: mushroom species mentioned in each group are listed at the end of the paragraph using the following convention: Latin name (common English names, if any).

Agaricaceae

The genus Macrolepiota, usually Macrolepiota procera, and, to a lesser extent, Macrolepiota rhacodes are highly regarded, especially in Europe, being very palatable and very large, with specimens of M. procera as high as one metre being reported.

Amanitaceae

While the family of amanitas are approached with extreme caution, as it contains the lethal Amanita phalloides and Amanita virosa, those confident in their skills often pick the Amanita rubescens, which is highly prized in Europe and to a much lesser extent in Russia, accounted by some not to superior taste, but to its relation to the Amanita caesarea, which is not found in Russia, but was considered a delicacy worthy of the emperor in Ancient Rome.

Boletaceae

This order is often viewed as the order of "noble" mushrooms, containing few poisonous species, identifiable with relative ease, and having superior palatability. The most notable species is the Boletus edulis, the "mushroom king", an almost legendary, relatively rare mushroom, edible in almost any (even raw) form, and commonly considered the best-tasting mushroom.[citation needed] (It is common to confuse the Russian name, literally "white mushroom", with champignons, often known in English as "white mushrooms".)

The genus Leccinum includes two well-known mushroom species named after the trees they can usually be found next to. The Leccinum aurantiacum (as well as the Leccinum versipelle), found under aspen trees, and the Leccinum scabrum (as well as the L. holopus), found under birch trees. The latter species, are significantly different in cap colour only. Both types are very sought after, being highly palatable and more common than the B. edulis.

The genus Suillus, characterised by its slimy cap, is another prized mushroom, the Suillus luteus and Suillus granulatus being its most common varieties, and while abundant in some parts of Eurasia, is a rare occurrence in others. It is easy to identify and very palatable.

The genus Xerocomus is generally considered a less desirable (though mostly edible) mushroom group, due to common abundant mould growth on their caps, which can make them poisonous. The Xerocomus badius, however is an exception, being moderately sought after, especially in Europe. Some scientific classifications now consider species in the genus Xerocomus as members of Boletus.

Cantharellaceae

Chanterelles

The Cantharellus cibarius is a common and popular mushroom in Europe. It is edible and highly palatable. It is very rarely infested by worms or larvae, has a unique appearance, and when rotting, the decomposed parts are easily distinguishable and separable from those that are edible.

Craterellus cornucopioides and Craterellus tubaeformis are also very popular mushrooms, and dry well.

Helvellaceae

The Gyromitra esculenta is considered poisonous, but can be consumed if dried and stored for over a year according to Slavic literature. It can be used to supplement or replace morel (see Morchellaceae below) mushrooms, while Western literature claims that even the fumes of the mushroom are dangerous. It is similar to morels both in appearance and palatability.

Morchellaceae

The morel, Morchella esculenta is highly prized in Western Europe, India and North America. It is significantly less prized in Slavic countries where it is considered marginally edible with mediocre palatability. Boiling the mushroom and discarding the water is often recommended.

Lactarius

Members of the genus Lactarius, as the name suggests, lactate a milky liquid when wounded and are often scoffed upon[clarification needed] by Western literature. The Lactarius deliciosus is however regarded as one of the most palatable mushrooms in Slavic culture, comparable to the Boletus edulis. Also considered as similarly palatable are the species Lactarius necator and particularly Lactarius resimus. Thermal treatment may however be necessary in some cases. The Lactarius pubescens has a less appealing, bitter taste.

Russulaceae

The Russula family includes over 750 species and is one of the most common and abundant mushrooms in Eurasia. Their cap colours include red, brown, yellow, blue and green and can be easily spotted. The Russula vesca species, one of the many red-capped varieties, is one of the most common, is reasonably palatable and can be eaten raw. The edible Russulas have a mild taste, compared to many inedible or poisonous species that have a strong hot or bitter taste. (This is not a defining feature of all poisonous mushrooms, deadly poisonous Amanita phalloides, Amanita virosa and many other poisonous mushrooms have mild tastes.) The Russula emetica (the sickener) is known to cause gastrointestinal upset and has a very hot taste when a small bit is placed on the tongue. Due to their abundance they may be regarded as an inferior mushroom for hunting. They may be eaten if parboiled.
