Lichen

Some interesting info about lichens. They do not have roots, don't need a water supply, can grown in locations impossible for most plants, can survive in space, are eaten by some cultures, have been used to extract purple and red colors and contain the substance olivetol that is also found in cannabis. I thought this was a nice looking specimen.

  1. So that's what that stuff is! I often see on my jaunts but did not know what it was called.

  2. Nice photo. Didn't know about these either. Knew the name but nothing about the characteristics.
    Went to Bernheim today looking for shots.
