Mushroom Fields

Mushroom fields or mushroom islands are rare biomes which always generate as islands surrounded by deep oceans. They are the only place in the game where mycelium and mooshrooms are found, and have the special property that no hostile mobs normally spawn in them.

Generation

Mushroom fields make up about 0.15% of the Overworld's area. They generate in areas where the continentalness values are the lowest, meaning they almost always generate as islands very far away from major landmasses, and are bordered by deep ocean biomes of any temperature. This means that ocean monuments generate almost always next to mushroom fields.

The islands have the occasional tendency to be close to one another, resulting in multiple mushroom fields separated by only a few hundred blocks. It is nearly impossible for the player to spawn in the mushroom fields biome.

Description

The mushroom fields generate in usually flat islands and have mycelium instead of grass blocks on the surface. Grass blocks that are placed by the player in this biome take on a bright green color, similar to the grass found in jungles. A large amount of brown and red mushrooms cover the land. It is one of the only biomes, along with swamps‌^{[BE only]} and dark forests, where huge mushrooms generate naturally. Sugar cane, short grass, and firefly bushes sometimes generate by the ocean.^[1]

The huge mushrooms generate with a density high enough to be a reliable source of mushroom blocks, but low enough not to significantly obstruct vision. Here, mushrooms can grow in full sunlight. Water is a light gray color in Bedrock Edition.

Mushroom fields are the only biome where mooshrooms naturally spawn. Red mooshrooms, bats,‌^{[JE only]} and glow squids are the only mobs that spawn naturally in this biome; this also applies in caves, mineshafts, and other underground structures, meaning the biome is mostly safe both above and below ground.

However, monsters spawned from other sources than the natural spawn cycle continue to spawn, such as monster spawners, raids, and phantoms.‌^{[JE only]}^[2] Lush caves can sometimes generate underground, allowing for monsters to spawn naturally. Additionally, lightning strikes can transform red mooshrooms into brown mooshrooms or vice versa. Wandering traders also spawn normally.

Mushroom fields have a unique sky color with Vibrant Visuals, which is yellow at the horizon and gray at zenith. At sunset, the horizon turns bright red, while at sunrise it is more purple/pink. At night, there is a dim purple light at the horizon. Mushroom fields also have slightly stronger volumetric fog, tinted by a unique purple sunlight.

History

Mention

July 1, 2011							Notch mentions the idea of a biome where huge mushrooms generate naturally.

Java Edition

Java Edition
1.0.0	Beta 1.9 Prerelease	Added Mushroom Island.
1.7.2	13w36a	With ocean biomes becoming much smaller, mushroom island biomes have become much rarer.
