Mushroom

Mushrooms are a type of fungi that currently function as a food item in Minecraft Alpha and Beta.



Like flowers, mushrooms can be collected but not cultivated - while mushrooms may be planted in direct sunlight (except on ice and glass), they will pop out of the ground in short order. This attribute allows mushrooms to be used in the creation of light-sensitive mechanisms. Mushrooms spawn in places with little natural light such as dungeons, cave entrances, deep underground, or under trees (particularly in forest biomes). They can also spawn above ground in the open, as long as the area is dark, so they can spawn out in the open during night. In extremely low light conditions, mushrooms thrive and thus have a more favorable chance of being found in The Nether. Mushrooms also emit a light level of 1. Mushrooms growing in the open will pop out of the ground when struck by sunlight, leaving a mushroom that may be picked up.

In Creative Mode, mushrooms were a decorative item and in Survival Test, a food and hazard. Pigs were able to eat mushrooms in Survival Test, but the feature has since been removed, along with sheep eating grass. In Indev, mushrooms are sometimes generated in rare instances under trees or in the shadow of other floating continents in the "Floating" map type. In the latest Beta version, mushrooms may be generated in the open when exploring during night. If mushrooms spawn in the night in the open, they will pop out when the sun hits, and you may come across a few random "popped out" mushrooms on the ground. As of the 1.2.0 update in Alpha, it seems that mushrooms are now more commonplace due to the addition of biomes.

Several bug reports have mentioned mushrooms growing on top of trees and remaining under direct sunlight without popping out of the ground. As this is a rare occurrence, searching for mushrooms on top of trees is probably not an efficient way to forage.

Brown Mushroom
As of Beta, brown mushrooms cannot be consumed. Brown mushrooms must be crafted with a Red Mushroom and a Bowl to yield Mushroom Stew.

Brown mushrooms healed in Survival Test, but from Indev onwards, they were unable to be eaten on their own. A brown mushroom emits 1 unit of light, just enough to be visible in absolute darkness. Brown mushrooms are somewhat rare in all survival-based game modes, although in The Nether realm mushrooms are sundry.

As of Alpha patch 1.2.2, there is a glitch that will cause any block with a brown mushroom to be nearly pitch black. This may have something to do with the fact that mushrooms need to be in darkness to survive, or that the mushroom set the light level back to 1 after lighting was already calculated.

Red Mushroom
As of Beta, red mushrooms cannot be consumed. Brown mushrooms must be crafted with a Red Mushroom and a Bowl to yield Mushroom Stew.

In Survival Test, the consumption of red mushrooms caused damage to the player's health. From Indev onwards, spotted red mushrooms are used along with brown mushrooms and a bowl to craft Mushroom Stew. Red mushrooms are also somewhat rare in all survival-based game modes, although they are much more abundant in The Nether due to the consistently low light conditions of the realm.



Trivia

 * Although they act like plants, mushrooms are actually types of fungi.
 * In Classic mushrooms could be placed on any block except enough mushroom, and would not break when the block below them was removed.
