These are trees that grow on your farm. They can be obtained at random in the Fall Season. There is an event that can occur from the second day of the season that means each tree has a 5% chance of turning into a mushroom tree. You can keep these trees around and tap them for resources, or you can chop them down and receive up to 5-6 red mushrooms. It is also worth noting that in the late game, the player will be able to purchase mushroom Tree seeds from Mr. Qi's Walnut Room.
