Cultivation of Oyster and Paddy straw Mushroom can meet the huge deficiency of nutrition to the marginalized people.
Mushroom is a living organism and biologically known as fungus (pl.
fungi). Its body is made up of cells that take the form of long filaments,
known as hyphae (sing. hypha), and its structure as well as chemistry
distinguishes it from other Kingdoms of Living World like Animal, Plant,
Protista and Monera. Fungi, numbering about 200,000 species and distributed all
over the world, have now earned the distinction of a separate Kingdom.
Mushroom is a fungus but every fungus is not
a mushroom. Large macroscopic fleshy fungi are known as mushrooms. In the
Kingdom of Fungi, the most species are microscopic and they do not come under
the category of mushrooms. The larger fungi, which reproduce by forming
mushrooms, flourish best in moist and shady habitats and biologically belong to
the two sub-divisions of Ascomycotina and Basidiomycotina, either is
characterised by the formation of a special type of sexual spore, the ascospore
and the basidiospore respectively. Each of these two sub-divisions of the fungi
is further divided into a number of Classes, Orders, Families, Genera and
Species. Mushroom growers in India are, however, concerned with only three
specific genera of the sub-division of Basidiomycotina for commercial exploitation
of the technology of mushroom cultivation. These genera include Agaricus,
Pleurotus and Volvariella. Agaricus is commonly known as button
mushroom, Pleurotus as oyster mushroom and Volvariella as
paddy-straw mushroom. The cultivation of mushrooms in India has earned some
considerable popularity in recent years with reference to the two Agaricus species
(Agaricus bisporus and Agaricus bitorquis), the two Pleurotus species
(Pleurotus sajor-caju and Pleurotus citrinopileatus) and the two Volvariella
species (Volvariella diplasia and Volvariella volvacea).
