Not an id, but don't know where else to go with this: Glow in the dark mushrooms (and not even genetically modified) http://www.pinktentacle.com/2006/05/rainy-season-brings-glow-in-the-dark-mushrooms/
I'll put it in Conversations and Chat for now - cool link. Maybe I'll restructure the site a bit when I get back from my Manitoba trip to add more "natural history" type forums.
