In a fruitless attempt to try to track down my lichen, I tried Bill's site which would let you enter various distinctive features of the lichen in question--but the choices were mind-boggling and the terminology there unclear.

One of the categories was propogation--something about spores. And this makes me wonder, algae and fungi in mind, how you'd classify one kind of spore when there are actually two organisms forming the lichen. Where's a botanist when you need one?
