Referenced many species of mushrooms such as bolates, death cap and  agarisus - and found that some species glow. And each of these species glow in different ways- some faintly, others only with glowing stems, other luminesce in solely the gill areas.

 

After narrowing the brightest species, I studied mostly Japanese Mycena Lux-Coeli mushrooms for inspiration. Since they were so small, limited to only fluorescent green glows, and rather plain in daylight, research was done on different species of sea nettles.

 

Sea nettle research provided insight on how one could paint patterns on a mushroom-like object. Reference photographs helped display how light could travel through partially transparent layers.
