Vile Mushroom

A Vile Mushroom is a type of mushroom found only in The Corruption, and is used solely to craft Vile Powder, which in turn is used to craft Worm Food when combined with Rotten Chunks, to upgrade Throwing Knives, and to convert Hallowed blocks to regular ones. Unlike other mushrooms, Vile Mushrooms can not be eaten.

A Vile Mushroom farm can be created by planting Corrupt Seeds or connecting dirt strips to existing Corruption. Care should be taken when farming Vile Mushrooms, as Eaters of Souls and thorns will spawn from corrupted grass, and Corruption spreads quickly, especially at Hardmode (you will need to remove all stone, sand and mud blocks in three square radius from corrupt grass). Completely containing a Vile Mushroom farm within a shell of non-dirt material, such as bricks, can control these hazards.
