Mushroom

A mushroom is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source. Mushrooms are not plants: they are a fungus. They eat organic matter, they do not photosynthesize like plants do. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus, hence the word mushroom is most often applied to those fungi (Basidiomycota, Agaricomycetes) that have a stem (stipe), a cap (pileus), and gills (lamellae, sing. lamella) on the underside of the cap.

"Mushroom" describes a variety of gilled fungi, with or without stems, and the term is used even more generally, to describe both the fleshy fruiting bodies of some Ascomycota and the woody or leathery fruiting bodies of some Basidiomycota, depending upon the context of the word.

Forms deviating from the standard morphology usually have more specific names, such as "puffball", "stinkhorn", and "morel", and gilled mushrooms themselves are often called "agarics" in reference to their similarity to Agaricus or their place Agaricales. By extension, the term "mushroom" can also designate the entire fungus when in culture or the thallus (called a mycelium) of species forming the fruiting bodies called mushrooms, or the species itself.

Variety of Orchids

Common Name : Orchid

Family : Orchidaceae

Orchidaceae, commonly referred to as the Orchid family, is a morphologically diverse and widespread family of monocots. It is currently believed to be the second largest family of flowering plants (only the Asteraceae is larger)

The complex mechanisms which orchids evolve to achieve cross-pollination were investigated by Charles Darwin and described in his 1862 book Fertilisation of Orchids.

Distribution
Orchidaceae are cosmopolitan, occurring in almost every habitat apart from deserts and glaciers. The great majority are to be found in the tropics, mostly Asia, South America and Central America, but they are also found above the Arctic Circle, in southern Patagonia, and even two species of Nematoceras on Macquarie Island, close to Antarctica.

The following list gives a rough overview of their distribution:
tropical America: 250 to 270 genera
tropical Asia: 260 to 300 genera
tropical Africa: 230 to 270 genera
Oceania: 50 to 70 genera
Europe and temperate Asia: 40 to 60 genera
North America: 20 to 26 genera

The following are amongst the most notable genera of the orchid family:
