Nylium

Nylium is a variant of Netherrack that generates in the Nether. It has two variants: warped nylium and crimson nylium.

Natural generation
Warped nylium generates in the warped forest biome, and crimson nylium generates in the crimson forest biome.

Block loot
Nylium can be mined only with a pickaxe. If mined without a pickaxe, it drops nothing. $$, nylium drops netherrack unless mined with Silk Touch.

Post-generation
bone meal on netherrack that is placed next to or adjacent to warped or crimson nylium transforms the netherrack into nylium of that type. No block can be above the netherrack during this process. This transformation can also be done by activating a dispenser with bone meal directly into that netherrack block.

Usage
Similar to grass blocks and mycelium, nylium decays (immediately on a random tick) when an opaque block is placed above it. However, unlike grass blocks and mycelium, it does not decay underneath water and lava.

Similar to grass, the player can apply bone meal to nylium. This nylium, along with nearby nylium, generate vegetation that occurs in their native biome (crimson nylium generates crimson forest vegetation and warped nylium generates warped forest vegetation).

$$, fungi must be placed on the same type of nylium to be grown into huge fungi using bone meal. $$, fungi can grow on any type of nylium (or grass blocks, dirt and mycelium).

Trivia

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