Mycelium is a block similar to grass, and will grow over any dirt in its area. even if it has a sapling or another plant on it, but it is only found naturally in mushroom biomes. This can be stopped by creating an obstruction to the Mycelium's expansion (such as a two-block change in terrain height or a non-dirt solid block).
Mycelium was first added in the first Beta 1.9 release, usable only in creative mode.
As of 1.2.4, mycelium is the only block players can spawn mushrooms on while in sunlight.
They were added to Pocket Edition in the 0.9.0 Update alongside Mushroom Biomes.
