Glowing fungus is a consumable item in Fallout 4.


Main article: Glowing fungus

Glowing fungus, or Flammulina velutipes,[1] is a mutated variant of the pre-War fungus. Common in temperate areas, the medicinal properties of the original mushroom have been enhanced by radioactive exposure, allowing it to be used in a variety of potent medicines, such as herbal treatments or even post-War RadAway. The mushrooms have also developed distinct bioluminescence, making them easily identifiable.[2]


It is a common and edible mushroom found in the wastes that induce a small amount of radiation when eaten. It is used in the recipe for RadAway, antibiotics, herbal anodyne, antimicrobial and stimulant in Survival mode. For the Chemist perk, this item is treated as a chem; the HP gained from consuming it will increase.
