A huge fungus is a large "tree" feature that generates in the Nether. There are two types of huge fungi: the huge crimson fungus and the huge warped fungus.

Variants

There are two variants of huge fungus:

Generation

Huge crimson fungi and huge warped fungi generate only in crimson forests and warped forests, respectively.

Blocks and items

These blocks can be obtained from the huge crimson fungus:

Crimson Stem
Nether Wart Block
Shroomlight
Crimson Planks (created from a crimson stem in the inventory crafting grid)
Weeping Vines

These blocks can be obtained from the huge warped fungus:

Warped Stem
Warped Wart Block
Shroomlight
Warped Planks (created from a warped stem in the inventory crafting grid)

Structure

The trunks of huge fungi are made of either warped stems or crimson stems depending on the type. Naturally generated huge fungus trunks can be either thick or thin: thick trunks grow up in a 3×3-plus shape, with stray stems sometimes in the corners, while thin trunks grow straight up as a 1×1 column. To determine the size of huge fungi, a random integer is chosen between 4 and 13 [inclusive]. There is then a ¹⁄₁₂ chance of that integer doubling. The resulting value is the height of the trunk. A layer of wart blocks and shroomlights is then spread around the trunk, being able to generate up to 3 blocks out from the trunk, and are the "leaves" of the fungus. There is a 3×3×2 hollow ring that surrounds the lowest block of a fungus where no blocks generate. Both variants have shroomlights generate inside them, replacing both the wart blocks and stems. Huge crimson fungi may also have weeping vines growing replacing the same, or from the underside of wart blocks. In this way huge crimson fungi may grow the weeping vines lower than the stems as well as initially generate replacing the stems, when naturally-generated uniquely along the local ceiling.

Growth

The smallest a huge fungus structure can be.

When bone meal is used on a fungus that is planted on matching nylium, this has a 40% chance to grow into its huge equivalent (similar to saplings and mushrooms). Crimson and warped fungi grow into crimson and warped huge fungi, respectively. The stem, shroomlight, or nether wart block do not replace blocks. A fungus does not grow by itself through random ticks, unlike saplings.

In Java Edition, if a huge fungus is grown with bone meal, its stem will always be the thin 1×1 variant.

Huge fungi grow even with blocks above them,^[1] and do not replace any solid blocks when grown; however, they do not grow if blocked by the world height limit, or if situated outside of the world.

Huge fungi can grow up to 27 blocks tall. The maximum space they can take up is 9×27×9 blocks (partially hollow), and the average is 213 blocks of volume.

Nether wart blocks and shroomlight persist when the stem of the huge fungus is removed, unlike how leaves decay when logs of a tree are removed.

Data values

ID

Java Edition:

Feature type	Identifier
[No displayed name]	`huge_fungus`

Configured feature	Identifier
[No displayed name]	`crimson_fungus`
[No displayed name]	`crimson_fungus_planted`
[No displayed name]	`warped_fungus`
[No displayed name]	`warped_fungus_planted`

Config

Java Edition:

[NBT Compound / JSON Object] config
- [NBT Compound / JSON Object] hat_state The block to use for the hat.
  - Block state see Template:Nbt inherit/block state/template
- [NBT Compound / JSON Object] decor_state The block to use as decoration.
  - Block state see Template:Nbt inherit/block state/template
- [NBT Compound / JSON Object] stem_state The block to use for the stem.
  - Block state see Template:Nbt inherit/block state/template
- [NBT Compound / JSON Object] valid_base_block The block to place this feature on.
  - Block state see Template:Nbt inherit/block state/template
- [Boolean] planted (optional, defaults to false) Whether this huge fungus is planted. If false, it can't exceed the world ceiling, can replace blocks whose material is plant, and doesn't drop items when replaced by other blocks.
- [NBT Compound / JSON Object] replaceable_blocks A block predicate. The predicate must pass for a block to be replaced by this feature.
  - [String] type: The type of the block predicate. See Block predicate § Types for options.
  - additional fields depending on [String] type. See Block predicate § Types.
