Mushroom

Mushroom is a small plant, brown or red, that spreads slowly in dim light.

Obtaining

Natural generation

Mushrooms generate in patches at a random height, mostly underground. An Overworld chunk gets a brown patch one time in four and a red patch one time in eight, and the Sky dimension uses the same rates. A Nether chunk gets one patch of each.

Breaking

Breaking a mushroom drops it, whatever breaks it.

Behaviour

Where a mushroom can stand

A mushroom stands on any full opaque block, leaves and the double stone slab included. Glass, ice, farmland, slabs, stairs and fences do not hold one.

Generating and spreading also need an air space with light 12 or less. The light is read without the time of day, so a space open to the sky counts as light 15 at midnight.

Spreading

On each random tick a mushroom has a 1 in 100 chance to try to spread, about once every 41,000 ticks. A try picks one block in the 3×3×3 cube around the mushroom and places a mushroom there if the space qualifies. The same level is twice as likely as the level above or below.

Nothing limits how many mushrooms stand together.

Staying put

A mushroom drops as an item when a block beside it changes and its spot no longer qualifies. Random ticks never remove one, so a mushroom in bright light stays until something beside it changes.

Placing a mushroom by hand skips the light test. One planted in daylight stays there and never spreads.
