Giant Glowing Mushroom

Mushroom trees are, like normal trees, destructible plants in Terraria that can be cut down with an axe; however they do not yield wood but Glowing Mushrooms and Mushroom Grass Seeds.

Mushroom trees cannot be planted by a player, and neither do they grow spontaneously. Instead, a number of mushroom tree "groves" are created during world generation: these areas are typically a large cavern with a vast quantity of mud presenting a flat surface, and covered with water.
