Mushtrees are naturally generated objects that act as light sources inside Caves.
The most common variant is a Blue Mushtree, which can be chopped down, providing 2 Logs and a Blue Cap. Using a Shovel or a Regal Shovel to dig up the stump that will provide another Log or burn it to yield 1 Ash. Mushtrees also come in green and red varieties, which drop a Green Cap and Red Cap respectively upon harvest, as well as a single Log. When set on fire, a Mushtree will eventually burn to a crisp and disappear, dropping 1 Ash and 1 Charcoal. Unlike Evergreens, which drop Pine Cones that can be planted, there is no way for the player to regrow Mushtrees, making them a nonrenewable resource.
Mushtrees are regarded as the easiest way to get Blue Caps. However, Mushtrees also provide a small, but free and unending source of light. Illumination frequently means life or death in the caves, so discretion should be used when deciding whether or not to harvest.
Reign of GiantsEdit
During Full Moons in the Reign of Giants DLC, Mushrooms (both in Caves and on the Surface) will turn into Mushtrees. If a Mushroom-turned-Mushtree has been chopped, its stump will turn into a harvested Mushroom spawn point once the Full Moon ends.
Don't Starve TogetherEdit
In Don't Starve Together, Mushtrees have a blooming state where they produce light-generating Spores. Additionally, a variant of the Blue Mushtree, called the Webbed Blue Mushtree can rarely be encountered. Webbed Blue Mushtrees will spawn Dangling Depth Dwellers from the nearby dens when chopped down.
Mushtrees also release Mushroom Spores when they are blooming, but their blooming season is different for each variety. Blue Mushtrees start blooming at night during Winter. Green Mushtrees start blooming at dusk during Spring. Red Mushtrees start blooming at day during Summer. All three types of Mushtrees are renewable through Regrowth, and will spawn during their blooming Seasons.
- According to Wickerbottom, Mushtrees are regular trees infected with fungal parasites.
