Omphalotus olearius, the Jack-o-Lantern, is bioluminescent and probably does not need any kind of saving at all. Actually I'm convinced they along with a huge number of other species will by far outlast the human race and be responsible for cleaning up our messes. As they have always done, restoring the soil layer by reducing complex molecules into simpler renewed building blocks, this IMHO is their primary function. I think that many of these characteristics i.e. bioluminescence, psychoactivity, and etc. are actually communicative in nature.
Locating a nice safe to walk path through good mushroom country in the daylight and hopefully one of the species with this characteristic is a good place to start. I have found a tree that jack-o-lanterns fruited on several years in a row and now I'm waiting so I can go and see if I can detect the glow in the dark (yes I'm goofy enough to wander around in the forest in the pitch black) but especially I want to set the camera up on a tripod and do some long exposures. Night vision gear would make easy work of this.
I'm pretty sure that I've seen several things glowing in the woods at night.............

Sorry to reply again, after having already replied, but I wanted to let everyone know:
I have contacted Professor Volk, the author of the entry on the "Jack-O-Lantern mushroom" URL included in the quoted text, via e-mail, asking him for tips on where I might possibly want to look for specimens of this mushroom this fast-approaching Autumn, in my area of the USA. I have also asked him if he has any suggestions as to which hardwoods might be most appropriate for a substrate, if I were to find an appropriate specimen to take a spore print from. I'm going to do more of my own research, but I feel it would be a good idea to take his advise if he responds, as he knows his stuff.
I wonder if, since this is a robust, wild-growing mushroom, if I could simply get away with taking an appropriate specimen, cutting the stipe away, and laying it down on the appropriate substrate, hoping that it decides to drop its spores. We have plenty of hardwood logs in my back yard destined for firewood, and I know how to identify some hardwoods thanks to my father being a Master Carpenter. I have made an inquiry regarding this very thing to professor Volk, so let's see if he finds the time to respond.
If I get a response from him, I will be certain to update, as I know I am not the only one who would love to have some of these fine little fellows growing in a mini terrarium for a conversation piece, and to introduce them to my backyard as well.
Arathu: Thank you so much for the link. :)
