Bioluminescent Mushrooms, Giving It a Try
Okay, so I just ordered one of those glowing mushroom (Panellus Stypticus) kits. They are supposed to be native to my area (the appalachians), so I figured I'd give growing them a shot. If they prove to be worth the trouble, I just might attempt to introduce them to my woods (again, since they're supposed to be native to this area, no worries about introducing an aggressive foreign species).
Only potential problem I can see there is that I've read that they prefer hardwood, and I've got a mostly pine forest out here. I'll have to see if they'll grow on fallen pine or not. We've got literally tons of rotting pine out here from the pine beetle plague that went through years ago, so there's plenty of deadwood out here that needs a helping hand in going away, and honestly it would be seriously cool to go outside on a moonless night and see the woods glowing.
Assuming these things glow bright enough to actually be seen from more than a few feet away, that is.
