Edible mushrooms are the fleshy and edible fruit bodies of several species of macrofungi (fungi which bear fruiting structures that are large enough to be seen with the naked eye). They can appear either below ground (hypogeous) or above ground (epigeous) where they may be picked by hand.[1] Edibility may be defined by criteria that include absence of poisonous effects on humans and desirable taste and aroma.[2][3]

Edible mushrooms are consumed by humans as comestibles for their nutritional value and they are occasionally consumed for their supposed medicinal value. Mushrooms consumed by those practicing folk medicine are known as medicinal mushrooms.[4] While hallucinogenic mushrooms (e.g. psilocybin mushrooms) are occasionally consumed for recreational or religious purposes, they can produce severe nausea and disorientation, and are therefore not commonly considered edible mushrooms.[5]

Edible mushrooms include many fungal species that are either harvested wild or cultivated. Easily cultivatable and common wild mushrooms are often available in markets, and those that are more difficult to obtain (such as the prized truffle and matsutake) may be collected on a smaller scale by private gatherers. Some preparations may render certain poisonous mushrooms fit for consumption.

Before assuming that any wild mushroom is edible, it should be identified. Accurate determination and proper identification of a species is the only safe way to ensure edibility, and the only safeguard against possible accident. Some mushrooms that are edible for most people can cause allergic reactions in some individuals, and old or improperly stored specimens can cause food poisoning. Great care should therefore be taken when eating any fungus for the first time, and only small quantities should be consumed in case of individual allergies. Deadly poisonous mushrooms that are frequently confused with edible mushrooms and responsible for many fatal poisonings include several species of the Amanita genus, in particular, Amanita phalloides, the death cap. It is therefore better to eat only a few, easily recognizable, species, than to experiment indiscriminately. Mushrooms growing in polluted locations can accumulate pollutants such as heavy metals.[6]

History of mushroom use

Mycophagy /mˈkɒfəi/, the act of consuming mushrooms, dates back to ancient times. Edible mushroom species have been found in association with 13,000 year old archaeological sites in Chile, but the first reliable evidence of mushroom consumption dates to several hundred years BC in China. The Chinese value mushrooms for medicinal properties as well as for food. Ancient Romans and Greeks, particularly the upper classes, used mushrooms for culinary purposes.[5] Food tasters were employed by Roman Emperors to ensure that mushrooms were safe to eat.[7]

Mushrooms are also easily preserved, and historically have provided additional nutrition over winter.[citation needed]

Many cultures around the world have either used or continue to use psilocybin mushrooms for spiritual purposes as well as medicinal mushrooms in folk medicine.

Current culinary use

A fraction of the many fungi consumed by humans are currently cultivated and sold commercially. Commercial cultivation is important ecologically, as there have been concerns of depletion of larger fungi such as chanterelles in Europe, possibly because the group has grown so popular yet remains a challenge to cultivate.

Mushroom cultivation has a long history, with over twenty species commercially cultivated. Mushrooms are cultivated in at least 60 countries[8] with China, the United States, Netherlands, France and Poland being the top five producers in 2000.

Some species are difficult to cultivate; others (particularly mycorrhizal species) have not yet been successfully cultivated. Some of these species are harvested from the wild, and can be found in markets. When in season they can be purchased fresh, and many species are sold dried as well. The following species are commonly harvested from the wild:

  • Boletus edulis or edible Boletus, native to Europe, known in Italian as Fungo Porcino (plural 'porcini') (Pig mushroom), in German as Steinpilz (Stone mushroom), in Russian as "white mushroom", in Albanian as (Wolf mushroom), in French the cèpe and in the UK as the Penny Bun. It also known as the king bolete, and is renowned for its delicious flavor. It is sought after worldwide, and can be found in a variety of culinary dishes.
  • Cantharellus cibarius (The chanterelle), The yellow chanterelle is one of the best and most easily recognizable mushrooms, and can be found in Asia, Europe, North America and Australia. There are poisonous mushrooms which resemble it, though these can be confidently distinguished if one is familiar with the chanterelle's identifying features.
  • Cantharellus tubaeformis, the tube chanterelle or yellow-leg
  • Clitocybe nuda - Blewit (or Blewitt)
  • Cortinarius caperatus the Gypsy mushroom (recently moved from genus Rozites)
  • Craterellus cornucopioides - Trompette de la Mort or Horn of Plenty
  • Grifola frondosa, known in Japan as maitake (also "hen of the woods" or "sheep’s head"); a large, hearty mushroom commonly found on or near stumps and bases of oak trees, and believed to have Macrolepiota procera properties.
  • Gyromitra esculenta this "False morel" is prized by the Finns. This mushroom is deadly poisonous if eaten raw, but highly regarded when parboiled (see below).
  • Hericium erinaceus, a tooth fungus; also called "lion's mane mushroom."
  • Hydnum repandum Sweet tooth fungus, Hedgehog mushroom or Hedgehog Fungus, urchin of the woods
  • Lactarius deliciosus Saffron milk cap - Consumed around the world and prized in Russia
  • Morchella species, (morel family), morels belong to the ascomycete grouping of fungi. They are usually found in open scrub, woodland or open ground in late spring. When collecting this fungus, care must be taken to distinguish it from the poisonous false morels, including Gyromitra esculenta. The Morel must be cooked before eating.
  • Pleurotus ostreatus (Oyster Mushroom)
  • Tricholoma matsutake the Matsutake, a mushroom highly prized in Japanese cuisine.
  • Tuber species, (the truffle), Truffles have long eluded the modern techniques of domestication known as trufficulture. Although the field of trufficulture has greatly expanded since its inception in 1808, several species still remain uncultivated. Domesticated truffles include

Other edible wild species

Many wild species are consumed around the world. The species which can be identified "in the field" (without use of special chemistry or a microscope) and therefore safely eaten vary widely from country to country, even from region to region. This list is a sampling of lesser-known species that are reportedly edible.

Conditionally edible species

Amanita muscaria, a conditionally edible species

There are a number of fungi that are considered choice by some and toxic by others. In some cases, proper preparation can remove some or all of the toxins.

  • Amanita fulva (Tawny Grisette). The Tawny Grisette must be cooked before eating.
  • Amanita muscaria is edible if parboiled to leach out toxins.[10] Fresh mushrooms cause vomiting, twitching, drowsiness, and hallucinations due to the presence of muscimol. Although present in A. muscaria, ibotenic acid is not in high enough concentration to produce any physical or psychological effects unless massive amounts are ingested.
  • Amanita rubescens (The Blusher). The Blusher must be cooked before eating.
  • Coprinopsis atramentaria is edible without special preparation. However, consumption with alcohol is toxic due to the presence of coprine. Some other Coprinus spp. share this property.
  • Gyromitra esculenta is eaten by some after it has been parboiled; however, mycologists do not recommend it. Raw Gyromitra are toxic due to the presence of gyromitrin, and it is not known if all of the toxin can be removed by parboiling.
  • Lactarius spp. - Apart from Lactarius deliciosus which is universally considered edible, other Lactarius spp. that are considered toxic elsewhere in the world are eaten in some Eastern European countries, and Russia after pickling or parboiling.[11]
  • Lepista nuda (Wood Blewit). The Wood Blewit must be cooked before eating.
  • Lepista saeva (Field Blewit, Blue Leg or Tricholoma personatum). The Field Blewit must be cooked before eating.
  • Morchella esculenta (Morel). The Morel must be cooked before eating.
  • Verpa bohemica - Considered choice by some, it even can be found for sale as a "morel", but cases of toxicity have been reported. Verpas contain toxins similar to gyromitrin[12] and similar precautions apply.

Use in traditional medicine

Medicinal mushrooms are mushrooms or extracts from mushrooms that are thought to be treatments for diseases, yet remain unconfirmed in mainstream science and medicine, and so are not approved as drugs or medical treatments.[13] Such use of mushrooms therefore falls into the domain of traditional medicine.

Preliminary research has shown some medicinal mushroom isolates to have cardiovascular, anticancer, antiviral, antibacterial, antiparasitic, anti-inflammatory, and antidiabetic properties. Currently, several extracts (polysaccharide-K,[14] polysaccharide peptide,[15] lentinan[16]) have widespread use in Japan, Korea and China, as potential adjuvants to radiation treatments and chemotherapy.[17][18]

The concept of a medicinal mushroom has a history spanning millennia in parts of Asia, mainly as traditional Chinese medicine.[19] Only a few mushroom extracts have been tested for potential efficacy. Preliminary research results for most other extracts are on isolated cell lines, animal research with rodents, or early-stage clinical human trials as pilot studies.[18]

Preparing wild edibles

File:Dried mushrooms.jpg

Some wild species are toxic, or at least indigestible, when raw. As a rule all wild mushroom species should be cooked thoroughly before eating. Many species can be dried and re-hydrated by pouring boiling water over the dried mushrooms and letting them steep for approximately 30 minutes. The soaking liquid can be used for cooking as well, provided that any dirt at the bottom of the container is discarded.

One recipe for Auricularia auricula-judae is to collect it while still soft, wash it thoroughly and cut it into thin slices. The prepared slices should be stewed in stock or milk for around three-quarters of an hour, and then served with plenty of pepper. The result is crispy and not unlike seaweed.[20]

The difficult task of identifying mushrooms in the wild, for culinary or recreational purposes, can result in severe poisoning.[21]

Mushrooms that have been exposed to ultraviolet (UV) light contain large amounts of vitamin D2.[24][25][26] Mushrooms, when exposed to UV light, convert ergosterol, a chemical found in large concentrations in many mushrooms, to vitamin D2. This is similar to the reaction in humans, where Vitamin D3 is synthesized after exposure to UV light.

Testing showed an hour of UV light exposure before harvesting made a serving of mushrooms contain twice the U.S. Food and Drug Administration's daily recommendation of vitamin D, and 5 minutes of UV light exposure after harvesting made a serving of mushrooms contain four times the FDA's daily recommendation of vitamin D.[24] High performance liquid chromatography analysis has also demonstrated the effect sunlight has on mushroom vitamin D2 content.[27]

The ergocalciferol, vitamin D2, in UV-irradiated mushrooms is not the same form of vitamin D as is produced by UV-irradiation of human skin or animal skin, fur, or feathers (cholecalciferol, vitamin D3). Although vitamin D2 clearly has vitamin D activity in humans and is widely used in food fortification and in nutritional supplements, vitamin D3 is often used in dairy products.
