    How interesting! If I walked by it, I never would have guessed that it was a living organism. Thanks for the enlightenment.

    It’s extremely interesting! Living on the seaside in Brittany, an area that has seen several major oil spills, I always thought the black marks on rocks were traces of oil spills.
    Now… How can I be sure if it is oil or if it is a lichen?

    Ah! but Edulis tells why it is more sought after.

    I grew up in Newburyport Massachusetts. There is a barrier reaf island, called Plum Island. At one end there are many rocks and many lichen. They are very interesting and I am so pleased to see a photograph of them.
    Thank you,

    Thanks for the lichen picture. I live in an area where there is lots of it and am curious about it, so the explanation was helpful.
