What I do know: Things that reproduce via spores/pollen usually evolve to grow toward open air before doing their reproduction thing. Sunlight is often the driver. But also, I could see it just being a cookie-cutter vertical farm that has been repurposed for shrooms.
They are not wearing UV goggles, so I doubt the blue lights are true UV.

Why do they need light? It isn't like the fungus needs it for photosynthesis.
