(when crafted into stew)

Mushrooms can grow in dark caves and shady areas. They are more readily available in swamp and mushroom biomes and the Nether due to its low light conditions. They have also been known to spawn in jungles. A brown mushroom alone will increase the air block it occupies by one light level. Red mushrooms are generally rarer than their brown counterparts.
Mushrooms can be collected by hand and planted on the ground in light levels below 13 and not directly underneath the sky. (except in the cases of mycelium or podzol blocks, where mushrooms will remain planted even under full sun).
Mushrooms grow only at light level 12 and below, except when planted on mycelium or podzol. Mushrooms grow at the same rate regardless of light level. Brown and red mushrooms grow at the same speed.
Planted mushrooms will grow into huge mushroom when bone meal is used on them provided they are planted on a dirt, grass, mycelium, or podzol block, and if they have sufficient room to grow. Mushrooms will pop out of the ground if water flows over them, they are pushed by a piston, or the light level goes above 12 and the block next to them updates.

|Ingredients||Input » Output|
|Mushrooms were a decorative item, having no crafting use and remaining in the ground when planted. Mushrooms could be placed on any block except another mushroom, and would remain planted when the block below them was removed.|
|Survival Test||Pigs were able to eat mushrooms and sheep dropped brown mushrooms. Brown mushrooms healed and the consumption of red mushrooms caused damage to the player's health.|
|Mushrooms were generated in rare instances under trees or in the shadows of other floating continents in the "Floating" map type.|
|Red and brown mushrooms could not be eaten on their own, but could be crafted together with a bowl to yield mushroom stew.|
|1.2||With the addition of biomes and the dimly-lit Nether, mushrooms became a more common sight.|
|1.6||Mushrooms could be generated in the open when exploring during night, or under low-light conditions such as those found under trees or overhangs. If planted in direct sunlight or a light level higher than 12 they popped out of the ground. Several bug reports mentioned mushrooms growing on top of trees, but this was a very rare phenomenon.|
|Mushrooms were given an ability to spread in light levels under 13 onto any square touching their own, including squares located upwards and downwards diagonally. Mushrooms could be placed on any solid, non-transparent, square including pumpkins, workbenches, furnaces, and chests. However, while mushrooms could be placed on Jack-'o'-lantern and glowstone blocks, they would not grow due to the brightness of these blocks.|
|1.8||Mushrooms' spreading ability was severely restricted - a mushroom would only spread if there were fewer than 5 mushrooms of the same type in a 9w x 9l x 3h area around the original mushroom. However, mushroom farming became easier in another way since Bone Meal could be used on mushrooms to grow huge mushrooms that dropped several individual fungi when harvested. Mushrooms could also be found more easily in the new swamp biome under vine-covered trees.|
|1.0.0||1.9pre1||A mushroom biome was added, an island composed of Mycelium blocks and populated by huge mushrooms and Mooshrooms, strange red cows with red mushrooms growing on their backs.|
|1.9pre2||A new crafting recipe was added involving brown mushrooms. Each one could be crafted with a unit of sugar and a spider eye to produce a fermented spider eye.|
|1.7.2||13w36a||The new item Podzol allows Mushrooms to grow on it regardless of the light level.|
|Pocket Edition Alpha|
|0.5.0||Mushrooms can now be farmed.|
- Sometimes you cannot place mushrooms. This is due to them requiring a light level dark enough to be grown on. However, you can grow mushrooms on Mycelium or Podzol at any point in the day.
- Red mushrooms bear a strong resemblance to Amanita muscaria (Fly Agaric) mushrooms. Consuming Amanita muscaria will cause delirium and hallucinogenic effects if their psychoactive properties have not been reduced by parboiling. Similarly, red mushrooms in Minecraft caused damage to the player in the Survival Test.
- Brown mushrooms are more common than red mushrooms in swamps, and this is balanced by mushroom biomes having mooshrooms, making red mushrooms more common there.
- Mushrooms are one of the few blocks an Enderman can pick up.
- Brown Mushrooms emit a very small amount of light but it's so small it has to be completely dark to notice it.
- If The Player (in Creative mode) enters the Void at the top of the Nether, they may find mushrooms on top of bedrock blocks.
- Often times mushrooms can be seen in a ring around trees, due to the shade surrounding it from the leaves.
