Mycelium is a block similar to grass, and will grow over any dirt or grass in its area, even if it has a sapling or another plant on it, but it is only found naturally in mushroom biomes. The best way to stop this over-take is by adding cobblestone or wood around the area you do not want Mycelium to take over.
Mycelium was first added in the first Beta 1.9 release, useable only in creative mode.
As of 1.2.4, mycelium is the only block players can spawn mushrooms on while in sunlight.
