Mushroom

Mushrooms are a type of flora in minecraft. Mushrooms function as a decorative item in Creative Mode, a food/hazard in Survival And a staple food item in Indev

Mushrooms do not grow in sunlight, instead loving low-light or dim areas, specially dry and dark caves. Mushrooms can commonly be found in the darker areas of a "Forest" map, or in the shadow of other floating continents in the "Floating" map type. Mushrooms also grow in "Hell"'s extremely low light conditions. Mushrooms can possibly grow after a map has been generated if the conditions allow mushroom growth (Needs confirmation)

Brown Mushrooms
In Survival Brown mushrooms heal 2 and 1/2 Hearts, In Indev A Brown mushroom is used along with a Spotted Red mushroom (and a bowl) to create Mushroom Stew which heals 5 hearts. Brown mushrooms are slightly rare in both modes.

Spotted Red Mushrooms
