Glowing Mushroom biome

Mushroom biomes are areas where Glowing Mushrooms can be found.

Surface Mushroom Biome
A surface level mushroom biome can be created by planting mushroom seeds on mud. If enough continuous blocks are created the background and music will indicate a transformation into the surface mushroom biome. On the surface the mushroom biome shows towering giant mushrooms in the background when it is not obscured by a wall. Giant mushrooms can grow to significant heights if room is allowed for them to grow, and can regenerate if chopped down. The sun is removed from the biome which gives the same lighting at night. An easy way to create a surface mushroom biome is to make a suitable house in an underground mushroom biome and occupy it with the Dryad. This allows the player to buy mushroom seeds and create a suitable biome with ease. Here is a video of what a surface mushroom biome looks like http://www.youtube.com/watch?v=xP8jthZZVEA

After the player enters hardmode and defeats at least one mechanical boss, an alternative method of making overground mushrooms becomes available with the Steampunker and the Clentaminator. The Clentaminator is extremely useful for creating overground mushroom biomes, using Purple Solution. The only area viable to be converted in to a mushroom biome using the Clentaminator is the Jungle, as it is the only overground biome where mud is plentiful.

The Truffle NPC can only have a house in the mushroom biome.

Note: Surface Mushroom Biomes will spawn very strong enemies, similar in strength to hardmode enemies in other biomes. For this reason it is not recommended for new players to create mushroom biomes close to their spawn point until they have sufficient gear.

Underground Mushroom Biome
Underground mushroom biomes are found anywhere below 0 depth, including in pockets deep in the underworld. Potential enemies include black slimes, mother slimes, and cave bats, though whether enemies are specific to the biome or drawn from adjacent biomes is unknown. Similar to the surface biome during the blood moon and in hardmode more difficult enemies spawn which are unique to the mushroom biome. Underground the mushroom biome shows smaller mushrooms everywhere as its background, unless obscured by a wall. Giant mushrooms can also grow here if there is enough vertical space, though unlike surface giant mushrooms they typically appear without branches.
