The dark room is focusing on Lichen this week and I just happen to have some available for a photo. "Lichen can actually be of benefit. It's a natural air quality indicator, as it absorbs everything in the environment around it, but only thrives when the air quality is clean. Lichens are used in deodorant, toothpaste, salves, extracts, and perfumes."
I never would have know what this was, if you hadn't said. Now I can see it, but at first I thought it was some sort of flower and was puzzling over the rest of the composition.
Fabulous photo,
