Mushroom

Mushrooms are fungi that grow and spread in dark areas.

Obtaining
Mushrooms can be instantly mined with anything.

Natural generation
Mushrooms naturally generate in poorly lit areas (light level of 12 or less), as well as in mushroom island biomes and the Nether.

Witch huts have a flower pot with a red mushroom inside. Mushrooms also generate inside woodland mansions.

Huge mushrooms
Mining a huge mushroom block drops up to 2 mushrooms of the same color.

Mobs
Shearing a mooshroom drops 5 red mushrooms and turns it into a normal cow.

Usage
Mushrooms can be planted and grown on blocks in light levels below 13 and not directly underneath the sky. If planted on mycelium or podzol, they can stay planted in any light level. Both brown and red mushrooms grow at the same rate regardless of light level.

Besides being mined directly, mushrooms are dropped as items if:
 * the block below them falls, is moved, or destroyed;
 * a fluid flows over them;
 * it is above light level 12 and a block updates next to it and it is not on podzol or mycelium.

Huge mushrooms
When bone meal is applied to a mushroom, the mushroom has a chance to grow into a huge mushroom of the same color, provided that it is on a proper block (dirt, coarse dirt, grass, podzol or mycelium), has enough space, and that the light level is dark enough.

Spread
Mushrooms will spread randomly onto nearby blocks when in appropriate conditions. They will spread only if there are fewer than 5 mushrooms of the same type in 9×9×3 area.

Light source
Brown mushrooms emit a barely visible light level of 1.

Decoration
Either type of mushroom can be planted in a flower pot.

Trivia

 * Mushrooms can generate on the leaves of trees.
