Mushrooms are excellent food sources for new players, though their scarcity and seemingly region-based growth patterns may make them difficult to find initially. However, it is speculated that dropping a mushroom by a tree will encourage others to spawn around it - so when you go picking for mushrooms, please try to leave at least one behind!
Mushrooms are also excellent healing cover ingredients on the go.
Mushrooms can be hollowed out with a spoon to create a container.
Mushrooms decay quite quickly inside the inventory, but appear to last months when dropped on the ground.
