[Rockhounds] colour perception, organic fluorescence, etc

[Kreigh Tomaszewski]

Kitty,

There is a fungus that breaks down dead wood that is luminous. It is 
not all that common, and you have to break open rotting logs to find 
it. When we go camping in Michigan we try to find some of it to mark 
the trail from the campsite to the latrine. It glows with a bright 
white light.
