The polypores, shelf fungi, or bracket fungi (order Polyporales) have tubes under the cap as in the boletes, but they are not in an easily separable layer. There has been a recent upsurge of interest in mushrooms as a source of biological active compounds of medicinal value including anti-cancer, anti-viral, immunopotentiating, hypocholesterolaemic and hepatoprotective agents. Popularly, the term mushroom is used to identify the edible sporophores; the term toadstool is often reserved for inedible or poisonous sporophores. The word fungus comes from the Latin word for mushrooms. These structures are also responsible for their common name, the club fungi.

Mushrooms major cultivated species also contain relatively large amounts of carbohydrate and fibre, ranging from 51% to 88% and from 4% to 20% (dry weight basis) (Mattila et al., 2000).Shiitake (Lentinus edodes) and some members of the genus Oyster (Pleurotus spp.) Fruiting bodies, produced near the edge of this mat, may widen the ring for hundreds of years. This method of dispersal has allowed for single species of fungi to be found all around the globe. One club fungus, the cauliflower fungus (Sparassis crispa), has flattened clustered branches that lie close together, giving the appearance of the vegetable cauliflower. Success!

However, their chief worth is as a specialty food of delicate, subtle flavour and agreeable texture. The morels (Morchella, Verpa) and false morels or lorchels (Gyromitra, Helvella) of the phylum Ascomycota are popularly included with the true mushrooms because of their shape and fleshy structure; they resemble a deeply folded or pitted conelike sponge at the top of a hollow stem. Learn more about their life cycles, evolution, taxonomy, and features. Nutrition. The sporophore of an agaric consists of a cap (pileus) and a stalk (stipe). of Fungal Biology) 8(5), 501–555, Doi 10.5943/cream/8/5/3 .

A mushroom is made from a collection of fungal cells called hyphae, which are woven together to produce a spore bearing mushroom. The mushrooms Are usually classified by their conditions ascomicetas or basidiomicetas, their edible or non-edible character, their poisonous or medicinal composition and their general fleshy or non-fleshy texture. As long as nourishment is available and temperature and moisture are suitable, a mycelium will produce a new crop of sporophores each year during its fruiting season. By fresh weight, the common commercially grown mushroom is more than 90 percent water, less than 3 percent protein, less than 5 percent carbohydrate, less than 1 percent fat, and about 1 percent mineral salts and vitamins. Other groups of fungi, however, are considered to be mushrooms, at least by laymen. Mushrooms, or toadstools, are the fruiting body common to many species of fungi and are used to store and release spores into the environment.
