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 climate, temperate regions of Canada and the United States.

Identifying mushrooms

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.

Safety and misidentification

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. Mushroom poisoning kills an average of seven people every year in the United States alone and sickens thousands more. Common safety advice requires that: * Only positively identified mushrooms should be eaten, and if one cannot positively identify a mushroom they should assume it to be poisonous and not consume it. * Mushrooms should be identified a second time during preparation, and cooked unless it can be verified that the species can be eaten raw. * Mushroom types should not be combined. * A sample of any mushroom not well-experienced with should be retained for analysis in case of poisoning. * Familiarity with information about deadly mushrooms that are look-alikes of edible ones is mandatory, as "deadly twins" differ regionally, * When picking mushrooms in an unfamiliar region, e.g. in a foreign country or in an area a considerable distance from one's usual foraging sites, it is mandatory to exercise great caution even with mushrooms that are positively identified as edible based on prior experience. Mushroom guides explaining local species should be studied thoroughly. * Mushrooms should not be gathered that are difficult to identify. This applies especially to the mushrooms of the genus ''Amanita'' and ''Cortinarius'' and "little brown mushrooms". * Only a small amount should be consumed the first time a new species is tried. People react differently to different mushrooms, and all mushroom species can cause an adverse reaction in a few individuals, even the common champignon.

Commonly misidentified/confused mushrooms

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: * False chanterelles (''Hygrophoropsis aurantiaca''), as the name suggests, can look like real chanterelles (''Cantharellus cibarius''). Real chanterelles do not have sharp gills, but rather blunt veins on the underside. False chanterelles are considered edible, but unpleasant tasting.Only mild symptoms have been reported from consuming them, and they are not considered to be poisonous. The Jack O'Lantern mushroom is also often mistaken for a chanterelle, and it is potently toxic. * False morels (''Gyromitra, Gyromitra spp.'' and ''Verpa, Verpa spp.'') resemble true morels. False morels have caps attached at the top of the stalk, while true morels have a honeycombed cap and a single, continuous hollow chamber within. * Immature ''Chlorophyllum molybdites'' can be confused with edible ''Agaricus'' and ''Macrolepiota'' mushrooms. * ''Scleroderma citrinum'' and immature ''Amanitas'' may resemble immature puffballs. The puffballs can be identified by cutting one in half and looking for a dark reticulated gleba or the articulated, nonhomogeneous structures of a gilled mushroom, respectively. * Highly poisonous ''Conocybe filaris'' and some ''Galerina'' species can resemble and grow alongside hallucinogenic ''Psilocybe'' species.

Little brown mushrooms

"Little brown mushrooms" (or LBMs) refers to a large number of small, dull-coloured agaric species, with few uniquely distinguishing wikt:macromorphology, macromorphological characteristics.For confirmation that this informal term is used in serious books: 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") 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. * ''Amanita muscaria'' (Мухомор Красный [Mukhomor Krasniy] - Red Fly-Killer; ''Fly Agaric, Toadstool'') * ''Psilocybe semilanceata'' (Псилоциба Сосочковидная [Psilotsiba Sosochkovidnaya] - Nipple-Like Psylocybe; ''Liberty Cap'')

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. 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.

Regional importance

*British enthusiasts enjoy an extended average picking season of 75 days compared to just 33 in the 1950s. *In Japan, particular mushroom types are hunted, with particular importance given to delicacies such as the Matsutake mushroom. *In Slavs, Slavic countries and Baltic States, Baltic countries, mushroom picking is a common family activity. “The Russians for absolutely bananas for fungus. Mushrooming is a commonplace tradition there, not the hallowed turf of the academic or connoisseur.” After a heavy rain during the mushroom season whole families often venture into the nearest forest, picking bucketfuls of mushrooms, which are cooked and eaten for dinner upon return (most often in omelettes with eggs or fried in butter) or alternatively dried or marination, marinated for later consumption. In Southern Lithuania mushroom hunting is considered a "national sport". They even host a Mushroom Festival ("Grybų šventė") in Varėna including a mushroom hunting championship. *In the United States, mushroom picking is popular in the Appalachian area and on the west coast from San Francisco Bay northward, in northern California, Oregon and Washington (state), Washington, and in many other regions.

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: *Bamfield, British Columbia – Bamfield Fungus Festival *Berwyn, Illinois, Berwyn, Illinois – Houby Festival *Boyne City, Michigan – Annual National Morel Mushroom Festival * Buena Vista, Colorado – Buena Vista Heritage's Mushroom Festival *Cedar Rapids, Iowa, Czech Village – Houby Days Festival *Eugene, Oregon – Mushroom Festival *Girdwood, Alaska – Fungus Fair *Kennett Square, Pennsylvania – Mushroom Festival *Lake Quinault Lodge in Washington's Olympic National Forest – Quinault Rain Forest Mushroom Festival *Madisonville, Texas – Mushroom Festival *Mendocino County (North of San Francisco) – Mushroom Festival *Muscoda, Wisconsin – Morel Mushroom Festival *New Plymouth, Taranaki, New Zealand – Mushroom Ball *Richmond, Missouri – Mushroom Festival *Telluride, Colorado, Telluride, Colorado – Telluride Mushroom Festival *Washington's Long Beach Peninsula – Wild Mushroom Celebration

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. The situation is treated with black humor in some Russian jokes#Chernobyl, Russian jokes.

Commonly gathered mushrooms

A large number of mushroom species are favored for eating by mushroom hunters. The Boletus edulis, 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 Alpha-amanitin, 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. *'' Agaricus bisporus'' (table or button mushroom) are an extremely common variety of mushroom and can be found at most grocery stores. Sales of this mushroom in 1996 reached $209 million in Canada. Another well known mushroom known as the ''portobello'' is a large brown strain of this fungus. *''Coprinus comatus'' (shaggy ink cap) decomposes into ink, and hence are prepared soon after picking and only young specimens are collected. While being a general mushroom hunting guideline, the avoidance of specimens growing in areas with high pollution is especially important with this family, as it is a very effective pollutant absorber. * ''Macrolepiota procera'' (parasol mushroom)

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. * ''Amanita caesarea'' (Caesar's mushroom) * ''Amanita rubescens'' (European blusher)

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. (It is common to confuse the Russian name, literally "white mushroom", with champignons, often known in English as "white mushrooms".) * ''Boletus edulis'' (''Hřib Smrkový, Dubák, Borowik szlachetny, Porcino, King Bolete, Cep, Steinpilz'') 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 ''Leccinum holopus, 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. * ''Leccinum aurantiacum'' (red-capped scaber stalk) * ''Leccinum scabrum'' (birch bolete) 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. * ''Suillus'' (klouzek, slippery Jack, butter mushroom) The genus ''Xerocomus'' is generally considered a less desirable (though mostly edible) mushroom group, due to common abundant Mold (fungus), mould growth on their caps, which can make them poisonous. The ''Boletus badius, 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''. * ''Xerocomus'' (mossiness mushroom) * ''Boletus badius, Xerocomus badius'' (''hřib hnědý'')

Cantharellaceae

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. * ''Cantharellus cibarius'' (chanterelle, yellow chanterelle, pfifferling) 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. * ''Gyromitra esculenta'' (false morel, beefsteak morel, lorchel)

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. * ''Morchella esculenta'' (morel, yellow morel)

Lactarius

Members of the genus ''Lactarius (fungus), Lactarius'', as the name suggests, lactate a milky liquid when wounded and are often scoffed upon 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. * ''Lactarius deliciosus'' (saffron milk-cap) * ''Lactarius necator'' (black pepper cap) * ''Lactarius pubescens'' (wooly milk-cap) * ''Lactarius resimus'' (pepper cap)

Russulaceae

The Russula family includes over 750 species of mushroom. They are one of the most common and abundant mushrooms in Eurasia. Their cap colours can be red, brown, yellow, blue and green. Due to their prevalence, large shape and bright colours, they 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. (However, this is not a defining feature of ''all'' poisonous mushrooms, as 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. Due to their abundance they may be regarded as an inferior mushroom for hunting. They may be eaten if parboiled. * ''Russula vesca'' (Russula)

Tricholomataceae

* ''Armillaria'' (honey mushroom, shoestring rot). The genus ''Armillaria'', with the popular species ''A. gallica'' and ''A. mellea'', being so similar that they are rarely differentiated, are palatable, highly abundant mushrooms. Generally found on decaying tree stumps, they grow in very large quantities and are one of the easier mushrooms to spot and identify. * ''Pleurotus ostreatus'' (oyster mushroom). It is the most commonly picked tree-dwelling mushroom and is often also artificially cultivated for sale in grocery stores. This sturdy mushroom can be quite palatable when young. Growing these mushrooms at home can be a profitable enterprise and some Russians engage in the activity. * ''Tricholoma magnivelare'' is a prized mushroom in North America. British Columbia exports large quantities of this mushroom overseas to Asia where it is in high demand. *''Tricholoma matsutake'' - = syn. ''T. nauseosum'', is a rare red pine mushroom that has a very fine aroma. Its fragrance is both sweet and spicy. They grow under trees and are usually concealed under fallen leaves and the duff layer. The mushroom forms a symbiotic relationship with the roots of a limited number of tree species. In Japan it is most commonly associated with Japanese red pine. However, in the Pacific Northwest it is found in coniferous forests of Douglas fir, noble fir, sugar pine, and Ponderosa pine. Farther south, it is also associated with hardwoods, namely tanoak and madrone forests. The Pacific Northwest and other similar temperate regions along the Pacific Rim also hold great habitat producing these and other quality wild mushrooms. In 1999, N. Bergius and E. Danell reported that Swedish (''Tricholoma nauseosum'') and Japanese matsutake (''T. matsutake'') are the same species. The report caused the increased import from Northern Europe to Japan because of the comparable flavor and taste. Matsutake are difficult to find and are therefore very expensive. Moreover, domestic productions of Matsutake in Japan have been sharply reduced over the last fifty years due to a pine nematode ''Bursaphelenchus xylophilus'', and it and it has influenced the price a great deal. The annual harvest of matsutake in Japan has since further decreased. The price for matsutake in the Japanese market is highly dependent on quality, availability and origin. The Japanese matsutake at the beginning of the season, which is the highest grade, can go up to $2000 per kilogram, while the average value for imported matsutake from China, Europe, and the United States is only about $90 per kilogram.
