The Mushroom Tree is a type of tree. This tree can only be grow by a special event in the Fall. Each day in Fall, there is a 5% chance that any of your 10 farm tiles will be selected. If there is a fully grown and untapped forest tree or stump on these tiles, that tree will transform into a Mushroom Tree (or stump). A Mushroom Stump will turn into a Mushroom Tree during the Spring.
Once your first Mushroom Tree is obtained, it will begin spreading seeds like other trees. Be cautious of placing items near a tree while it’s growing, if items are too close the growth process will halt.
You can tap the Mushroom to obtain Common Mushrooms, Red Mushrooms, and Purple Mushrooms.
