Lampenflora

Lampenflora, also known in English as lamp-flora[1] or lamp flora[2] are autotrophic lifeforms present in natural or artificial caves associated with permanently installed lighting.

The requirements for the development of lampenflora are sufficient (artificial) light and moisture.

The germs, seeds or spores can get brought into the cave by air, water, animals or people.

[7] In the aphotic (lightless) part of caves, short-term growth of photosynthetic plants is possible thanks to the seed's nutritive tissue.

The weak acids excreted by lampenflora can also cause damage to and change limestone and other rocks.
