 Bed-able mushroom, bed-able mushrooms are the fleshy and edible fruit bodies of several species of macrophungi fungi which bear fruiting structures that are large enough to be seen with the naked eye. They can appear either below ground-hypo-juice or above ground-hypo-juice where they may be picked by hand. They may be defined by criteria that include absence of poisonous effects on humans and desirable taste and aroma. Bed-able mushrooms are consumed for their nutritional value and occasionally for their supposed medicinal value. Mushrooms consumed by those practicing folk medicine are known as medicinal mushrooms. While psychedelic mushrooms are occasionally consumed for recreational or entheogenic purposes, they can produce strong psychological effects and are therefore not commonly used as food. Bed-able 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, matzutake and morelle 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. Their determination and proper identification of a species is the only safe way to ensure credibility, 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. Right 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 genus Amonite. In particular, Amonite is thaloids, the death cap. It is therefore better to eat only a few, easily recognizable species, than to experiment indiscriminately. Moreover, even normally edible species of mushrooms may be dangerous, as mushrooms growing in polluted locations can accumulate pollutants such as heavy metals.
