Giant Glowing Mushroom

Mushroom trees are destructible fungi in Terraria that can be cut down with an axe like normal trees; however, they do not yield Wood, but Glowing Mushrooms and Mushroom Grass Seeds, and they look like tall glowing mushrooms. Mushroom Trees also give off light like mushroom grass.

They have similar requirements as trees to grow:
 * The ceiling must be at least 15 tiles above the floor.
 * They will grown only when there's a flat patch of 5 blocks.
 * They will grow at least 2 tiles from each other.
