Xanthoria parietina/Anzia colpodes

In other words, lichens but not just any old lichen. Xanthoria parietina was chosen model organism for genetic sequencing back on 06. Once it took years to do sequencing and then months to weeks. Now from what I have heard, it takes only a few hours. Any volunteers?

A wonderful day to be visiting Mt. Mitchell. Heavy clouds were rolling by giving the forest and eerie look, plus the temperature at 1000 hrs (AM) 57° F. I was love'n it!

Though I had my 30D with the 100mm f/2.8 macro with me, I opted mostly for the G7, pushing it as best I know how to the limits to see how well it will perform compared to my 30D. The only problems I am encountering at the moment in manual mode of operation, is getting the aparatures and the flash to coincide with one another. I keep blowing out images most of the time by getting too close and using the flash. Though the intensity of the flash can be adjusted, I still have to get used to using it. Overall though, the G7 is doing fantastic as a small light travel camera. That last image is a crop from 100% by the way, using Photo Impact 6

Beautiful images Ken I particularly like pic3 which IMO would make a great wall hanger at poster size.

Hey thanks Bruce!

You know I think you are right, that would make a great poster. Sure would beat the one I have of Bob Dylan.

Thanks Doug, it is not too often that one finds lichens with a bit of color to them.

The diversity of lichens in the mountains can be somewhat overwhelming. There are many species of these organisms and they can sometimes be very hard to identify. Some are colorful, while others are not and sort of bland, I think, in their appearance but interesting nonetheless. They are an indicator of air quality and the more them you have and the greater the diversity of them, the better. Thanks jmlphoto
