That's great man, could you PM the link to me?
I'd love to page around and see what they have for sale.
That Moss Gardening book is pretty good but If you wanted a more serious study on Lichens, there's a great big book (at most borders and barnes & noble) the Lichens of North America that's a book! It's a weighty and pricey volume but definately the one to get for stuff you'll find creeping along in our forests. There's an Encyclopaedia of Bryophytes too but I Missed my chance to get that one. I hate buying a book I can't page through before purchasing.
I can't wait to see your tank! [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]
