An Image Sealed With a Kiss

Crustose lichen on fallen log

I knew of course that I was photographing a log, but when I saw the isolated details through my camera, I was mesmerized by an abstract world of shapes and colors. Looking at the image afterwards, however, I began to see the white blobs as central characters. Then the characters became animals. Finally, one of the animals kissed the other.

I now know that the kissing blobs are a form of crustose lichen. Crustose lichens, as their name implies, form crust-like structures – in this case, on a rotting log. All lichens are made up of algae or bacteria (the plant part that provides the photosynthesis) and fungi (the part) that provides structure. The black outline of these blobs — a painterly effect of nature — is due to the wearing away of top structural layers, exposing the underlying threads (hyphae) that attach the lichen to the log. Learning the science of the image didn’t spoil it for me. It’s semi-abstract quality was sealed with the kiss.
