Mycelium is a rare dirt variant found exclusively in mushroom fields biomes.

Mycelium can be obtained by mining it with a Silk Touch-enchanted tool; otherwise, it drops Dirt. It naturally generates in mushroom fields and can spread to adjacent Dirt blocks under suitable lighting conditions. Unlike Grass and Podzol, Mycelium supports mushroom growth at any light level, making it ideal for mushroom farming. It cannot be tilled into Farmland but can be converted into Dirt Path using a shovel. If covered by a solid block and exposed to low light, Mycelium reverts to Dirt.
