Nylium is a variant of netherrack that generates in the Nether. It has two variants: crimson nylium and warped nylium, each spawning in different biomes.

The suitable tool to break nylium is a pickaxe. Nylium needs to be broken with a pickaxe; otherwise, the breaking time increases and the block drops nothing.

Nylium drops 1 netherrack block when it's destroyed using a tool without Silk Touch.
Nylium drops itself when it's destroyed using a pickaxe with Silk Touch.

Crimson nylium generates in the crimson forest biome, and warped nylium generates in the warped forest biome.

Nylium is dropped when an enderman dies while holding it.

Item	Structure	Container	Quantity	Chance
Java Edition and Bedrock Edition
Crimson Nylium	Bastion Remnant	Hoglin stable chest	2–7	22.8% { "item": "Crimson Nylium", "stacksize": "2–7", "chance": 0.22793887963348602, "structure": "Bastion Remnant", "container": "Hoglin stable chest" }

Using bone meal on netherrack that is placed next to or adjacent to crimson or warped nylium transforms the netherrack into nylium of that type. Only certain blocks (mainly transparent blocks) can be directly above the netherrack during this process, including but not limited to air, glass blocks, chests, and slabs ‌^{[Java Edition only]}. Note that some transparent blocks, such as glowstone, prevent this process. This transformation can also be done by activating a dispenser with bone meal directly into that netherrack block. If both types of nylium are present, there is an equal chance of either being spread.

This feature is exclusive to Bedrock Edition.

 

As netherrack generates in nether portals that spawn floating, using bone meal on netherrack turns it into nylium, making it renewable.

Similar to grass blocks and mycelium, nylium decays (based on random ticks) into netherrack when an opaque block is placed above it. However, unlike grass blocks and mycelium, it does not decay underneath water or lava.^[1] It decays when covered with snow.^[2]

Like mycelium and podzol, mushrooms can remain on nylium blocks in any light level. Huge mushrooms can be grown by using bone meal on mushrooms planted on nylium.

Nether fungi can likewise be grown into huge fungi using bone meal, although the fungus must be placed on the same type of nylium, or the bone meal in Java Edition is never consumed; but in Bedrock Edition it is consumed even though it never grows.

Nylium is also the only block on which the fungus of its type can be grown.

Similar to grass blocks, the player can apply bone meal to nylium. This nylium, along with nearby nylium, generates vegetation that occurs in its native biome (crimson nylium generates mostly crimson forest vegetation and warped nylium generates mostly warped forest vegetation), and just like in the native biomes, the opposite type of fungi occasionally generates. The vegetation is generated in a 5×5 area centered on the nylium block on which bone meal is used.

September 28, 2019							Crimson and warped nylium are announced at MINECON Live 2019.
							When these blocks are placed, they play planks sounds.

Java Edition
1.16			20w06a				Added nylium.
			20w07a				Warped nylium now has a 1⁄109 (~0.92%) chance of being offered by piglins when bartering, in a stack size of 1, making it renewable.
			20w09a				Warped nylium now has a 5⁄226 (~2.21%) chance of being offered by piglins when bartering, in a stack size of 1–5.
							Nylium now decays into netherrack when an opaque block is placed above it, making crimson nylium renewable as it's possible to convert netherrack into it.
			20w10a				Warped nylium can no longer be obtained by bartering with piglins, making both nylium variants no longer renewable.
			20w12a				Nylium can now be fertilized with bone meal to grow crimson roots, warped roots, Nether fungi and nether sprouts.
			20w16a				Crimson nylium now generates in chests within bastion remnants.
			20w22a				Nylium now drops netherrack, unless broken with Silk Touch, in which case it drops itself.
1.16.2			20w27a				Mushrooms can now be placed and grown on nylium at any light level.

Bedrock Edition
1.16.0			beta 1.16.0.51				Added nylium.
							Nylium can be fertilized with bone meal to grow crimson roots, warped roots, and Nether fungi.
			beta 1.16.0.57				Crimson nylium now generates in chests within bastion remnants.
26.20 Experiment Drop 2 of 2026			Preview 26.20.23				Added sulfur cubes, which have the ability to absorb nylium, providing the football/regular effect to the mob.

• The name is a portmanteau of "Nether" and "Mycelium", the name of the part of a fungus analogous to roots.
