There are three types of Mushrooms; Red, Green, and Blue. They can be used as vegetables or filler in Crock Pot recipes, or given to a Pig to produce Manure. Each mushroom has different effects on Health, Hunger, and Sanity, therefore, a player needs to know the advantages and disadvantages of their effects and think hard before consuming them. However, when combined effectively, mushrooms are a very synergistic food.
Mushrooms can only be picked at certain times of the day:
Each mushroom will re-grow after 0.63-1.25 days of Rain. They can also be dug up at any time using a Shovel to obtain two mushrooms, but the mushroom spawn will be destroyed. Mushrooms do not grow during Winter.
Red Mushrooms are typically found in Grasslands or Forests and can only be picked during the day. Chopping down a Red Mushtree will also yield a Red Cap in addition to a Log. Red Mushrooms have the worst effects of all the mushrooms, both raw and cooked.
Red Cap -20 +12.5 0
Cooked Red Cap +1 0 -10
Red Mushrooms can be dropped on the ground to indirectly damage Mobs if they eat it.
Blue Mushrooms are good for regenerating health when raw, or retaining sanity when cooked. Green Mushrooms are good for going insane when raw, or regaining sanity at minimum cost when cooked. Red Mushrooms are good for giving to Pigmen, luring Gobblers, and using as Crock Pot filler.
Red Mushroom damaging Mobs that eat it is especially useful when dealing with Gobblers as 3 Red Mushrooms in a stack can kill one Gobbler, providing Drumsticks.
If a ghost player haunts a mushroom in Don't Starve Together, it is possible to change the type of mushroom that it is, such as from red to blue.
Wormwood's health is not affected by edible items, so a Raw Red Mushroom is an effective food source in the early game.
Rings of Mushrooms can be found in some worlds as Set Pieces. These resemble Fairy Rings, which are naturally occurring rings of mushrooms that are thought to have supernatural origins in various mythologies.
Although they are considered vegetables in Don't Starve, mushrooms are body parts of fungi, and are technically not plants. However, they act more like vegetables than anything else during digestion.
The red mushroom's appearance and toxicity is likely based on the Amanita muscaria which contain a toxin that causes hallucinations and intoxication.
The raw Green Mushroom's insanity is likely based on real life Psychedelic Mushrooms.
If a mushroom is picked as it sinks into the ground, the player will receive a mushroom but the hole the mushroom left would look like the mushroom is still there and sleeping. The player will still view the mushroom as if it were picked already.
Sometimes Mushtrees will not transform back into normal mushrooms when the day starts.
