Mushroom

"Wait, go back a minute. Plant life? NO! Mushrooms aren't actually plants. All plants contain a chemical called chlorophyll which they use to turn sunlight into energy, and which also makes them green, but mushrooms don't have chlorophyll at all. Instead, they get their energy by breaking down decaying organic matter. So what are they then? They're fungi, which is a category all of its own, and also includes yeasts and moulds. Fungi don't get as much attention as plants, because they tend to live in soil or underground where they can't be seen. In fact, they're genetically closer to animals than they are plants. Think about that next time you cook up a mushroom stew."

Mushrooms are fungi that grow and spread in dark areas.

From block loot
Mushrooms can be instantly mined with anything. Mining a huge mushroom block drops up to 2 mushrooms of the same color.

From mob loot
Shearing a red or brown mooshroom drops 5 mushrooms of the corresponding color and turns it into a normal cow.

Natural generation
Mushrooms naturally generate in poorly lit areas (light level of 12 or less). If this condition met, each chunk has $1/8$ (12.5%) chance to generate red mushroom and $1/4$ (25.0%) chance to generate brown mushroom.

Mushrooms can also generate in extremely bright conditions, namely on top of glowstone; this has been strongly considered by non-Mojang sources to be an intentionally programmed feature.

Mushrooms also generate on surface in swamp, giant tree taiga, mushroom fields biomes and anywhere in the Nether.

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

Fallen trees
$$, fallen oak, birch, spruce, and jungle trees have 0–2 mushroom generated on horizontal logs.

From trading
Mushroom can be bought from wandering trader for an emerald.

Info
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 the 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 (7x7x9), and that the light level is dark enough.

Spread
(this spreading mechanic has been checked for version 1.15.2)

If a random tick is called on a small Mushroom (red or brown), in 96% of the cases nothing happens.

In 4% of the cases, the mushroom tries to spread.

It will first check if there are 5 or more mushrooms of the SAME type in a 9x3x9 (X, Y=height, Z) area, with the mushroom being in the center of that area. The mushroom counts as well. If this check is true, the spreading fails.

Next the mushroom's position is safed as the current position.

a random block* will be chosen in a 3x3x3 area around the current position. (the mushroom can be chosen as well). If that block is air and the block below is a valid block** the current position is set to that of the random block.

^this will happen 3 more times. That means the current position can potentially be anywhere in a 9x9x9 area around the original mushroom.

If the current position is air and the block below is a valid block, a new mushroom will come into existence here.

the random block* has a 50% chance to be on the same height level the original mushroom was on. 25% of being one height level below and 25% of being one height level above.

valid block**: any block you can manually place a mushroom on, which should be the case for all solid blocks, is valid if the lightlevel on the block is less than 13. The light level can be anything on mycelium and podzol.

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

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

Composting
Placing a mushroom into a composter has a 65% chance of raising the compost level by 1.

History

 * Mushrooms are decorative items, which currently do not have a crafting use and remain in the ground when planted.
 * Mushrooms can be placed on any block except another mushroom and remain planted when the block below them was removed.}}

Trivia

 * Mushrooms can generate on the leaves of trees.
