Lumenmould
From Warhammer 40k - Lexicanum
Lumenmounds are a phosphorescent fungus which provides light for most of the Black Holds growing in the toxic sludge lining most decks. Crude greenish-yellow light sources can be made by scraping the mould and sludge into clear containers, or its slime can be used as body paint. A patch of lumenmould lights an area dimly for five metres.[1]
