# An [[altar]] of Libila will create mycelium on randomly chosen tiles within its influence. This way is needed to start a mycelium patch, but drops in efficiency as more and more tiles picked already are infected.
# Existing mycelium spreads to nearby tiles much the same way grass and flowers spread.
# A priest/champion of Libila can cast [[Fungus]] to spawn mycelium.Mycelium requires Libila or [[HOTSHorde of the Summoned|HotS]] influence to grow and survive. If both are missing, the mycelium will start disappearing extremely slowly.
Mycelium can grow on these [[tile]]s:
* [[Grass tile|Grass]]
* [[Tree]]s
* [[Dirt tile|Dirt]]* [[Packed dirt tile|Packed Dirt]] ''(It is best to pack dirt tiles to slow growth.)'' Mycelium turns to dirt if you dig on it.
