Observation 11906: Rhizocarpon geographicum (L.) DC.
When: 2008-10-02
No herbarium specimen

Notes: Only a portion of this photo may be visible. The floppy disc that I use to store my photos on apparently has portions which are corrupt. Nonetheless, this is the only photo of this particular lichen I have, and I hope enough of the photo will show to identify it. It is a peculiar golden green coloration, quite striking on the blackish andesite (a kind of lava) rock. The lichen is plate-like, and forms many small individual colonies which do not appear to want to grow together, or rarely so. The photo shows more green than gold, but there were definate hints of gold in the actual lichen.

Recognized by sight: Yes, a striking lichen, and rarely so extensive — quite a find, too bad the photo didn’t turn out better! :) There are, alas, several species in the R. geographicum group, but as Arora would say, it’s all academic in the face of such beauty.

Floppy disk

I suggest a 1GB or bigger SD card. Floppy disks are sooo last millennium. :)

(Most of the photos I take will not even fit on a floppy. Let alone more than one. Let alone 50 to 100 or more from a single expedition.)
