Mushrooms1





Different types of Mushrooms/Fungi
There are many different kinds of mushrooms. One of the most common of them are Pleurotus Ostreatus (oyster mushroom), Pleurotus eryngii (King Oyster), Agaricus subrufescens (almond mushroom), hypsizygus ulmarius (white elm mushroom or elm oyster), Hypsizygus tessulatus (shimeji), Coprinus comatus (shaggy mane), Lentinula edodes (shiitake), Hericium erinaceus (Lios’ Mane), and Grifola Frondosa (maitake). Out of these, the most commonly grown are Sporophores which are chiefly in the agaric family (Agaricaeae). These are the kind that grow in your yard-in the grass/forest-outside along the barks of trees. There are over three thousand different types of mushrooms growing in North America alone. Some are very common, but many are found only rarely in special habitats.
Mycelia
Mushroom mycelia may live hundreds of years or die in a few months, depending on the available food supply. As long as nourishment is available and temperature and moistures are suitable, a mycelium will produce a new crop of Sporophores each year during its fruiting season. Fruiting bodies of some mushrooms occur in acs or rings called fairy rings. The myscelium starts from a spore falling in a favorable spot and producing strands (hypahe) that growing all directions, eventually forming a circular mat of underground hyphal threads.
Polypores
Polypores usually grow on living or dead trees, sometimes in destructive pests, or in somewhat damp areas. Many of them renew growth each year and thus produce annual growth layers by which their age can be estimated. Examples include the dryad’s saddle, the beefsteak fungus, the sulfur fungus, and species of the genera Fomes and Trametes.
Poisonous Mushrooms
Poisonous mushrooms may be very harmful to your health. This is why can be very important not to pick ordinary mushrooms out of the wild and eat them. Also called toadstool poisoning, toxic, sometimes fatal, effect of eating poisonous mushrooms (toadstools). There are some seventy to eighty species of mushrooms that are poisonous to man; many of them contain toxic alkaloids (muscarine, agaricine, phalline). Among the mushrooms that most commonly cause poisoning are Amanita muscaria. A. phalloides, and the related destroying angels. The ingestion of A.muscaria (fly agaric), which contains muscarine and other toxic alkaloids, is soon followed by nausea, vomiting, diarrhea, excessive salivation, perspiration, watering of the eyes, slowed and difficult breathing, dilated pupils, confusion, and excitability. Illness usually begins within six hours after eating the mushrooms, and recovery takes place within twenty-four hour period. A. phalloides, the death cap, or death cup, is far deadlier than the muscarine type; it contains heat-stable peptide toxins, phalloidin and two amanitins, that damage cells throughout the body. Within six to twelve hours after eating the mushrooms, violent abdominal pain, vomiting, and bloody diarrhea appear, causing rapid loss of fluid from the tissues and intense thirst. Signs of sever involvement of the liver, kidneys, and central nervous system soon appear; these effects can include a decrease in urinary output and a lowering of blood sugar. This condition leads to coma, which in more than fifty percent of the incidents, results in death. The species Gyromitra (Helvella) esculenta contains a toxin that is ordinarily removed during cooking, but a few persons are highly susceptible to it. The chemical nature of the toxin has not been determined, but it is a source of monomethylhydrazine, which affects the central nervous system and induces hemolytic jaundice. In the pictures at the end of the report, the second page includes pictures of the most common mushrooms ( These include poisonous, and non-poisonous ).
Amanita Poisonings
Some victims of severe Amanita poisonings have been successfully treated with a combination of thioctic acid, glucose, and penicillin or by passing the blood through a charcoal filter. Prevention rests upon the avoidance of ingestion of all wild mushrooms.
Enzymes
Mushrooms need carbohydrates, proteins, certain vitamins, and other nutrients. To obtain this food, the mycelium releases proteins called enzymes from its hyphae. The enzymes convert the materials on which the hyphae grow into simpler compounds that are absorbed by the mycelium.
Reproduction
Typically, a mature mushroom releases hundreds of millions of spores. The slightest air current can carry the sport great distances. However, only a few spores land in places with enough food and moisture for survival.
Agaricus Campestris
The common field mushroom (Agaricus campestris) is white with a somewhat pinkish-brown gills. It is umbrella-shaped, stocky, and solid. These are the mushrooms sometimes
