Talk:Glowing Mushroom Biome/@comment-24472482-20140222215228/@comment-24680207-20140427174115

They can only spread through mud blocks so if you only placed one mud block, then it will not spread to regular grass, I suggest going to the Jungle/Underground Jungle and mining some mud blocks. And you cannot grow a mushroom biome below "Level" use a GPS or Depth Meter to make sure you are at or above Level.
