Glowing Mushroom Biome

The Surface Glowing Mushroom biome is a biome that can be created on the surface of the world by planting mushroom grass seeds in mud and allowing it to grow. It's unknown whether it can occur during world creation. The Surface Glowing Mushroom biome will not occur above sea level but below the surface; it seems to need to grow in daylight. Once part of the surface is converted to a Surface Glowing Mushroom biome, stars will come out and the sun will disappear (even during the day).

The Surface Glowing Mushroom biome is similar to the underground Glowing Mushroom biome, but with slightly different mushroom trees and apparently fewer enemies.

A Surface Glowing Mushroom biome is necessary to summon Truffle.
