Huh? I spent a sizable part of my undergraduate years collecting lichens in the Smokey Mountains, and I didn't expect then that all lichen species would be discovered in my lifetime. You obvioulsy have a very cloistered view of the world. Maybe you really should spend some time reading the materials I linked above in post 14. Or at least get out of your living room once in a while.
