Spotting

By the way, you can find more information about lichens here:

Nice spotting Lipase. Lots of different lichens. I think that the white one of pic #2 and the grey one of down left corner of pic #3 are Graphis scripta, although there are a variety of very similar species like Graphina sp. and Phaeographis. It is a pity you do not give more information about the habitat. It would be good if you also specify the kind of tree on which they have been spotting. It could help to identify the lichens. Still, good spotting! Congratulations!!

kewl!

Wow, very cool. It reminds me of Gustav Klimt's work.
