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.

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.

Trivia

 * According to Wickerbottom, Mushtrees are regular trees infected with fungal parasites.
