Octopus Lichen


Today I was pruning out the demon canker from an old apple tree.  This fungal disease is systematically munching through its aged branches.  Although disfigured by this nibbling, it is blessed by a natty outfit comprising an assortment of lichen, including this one.  North Devon has a lot of lichen.  I am definitely not an expert (at or in anything) but I presume that our propensity in the South West to damp and mild weather is in the lichen’s favour.  Our low levels of pollution also help.  To further your education I have extensively researched (I googled “disc lichen” and scrolled down a bit) and have come up with Lecanora chlarotera as a possible identification.  Unfortunately it doesn’t seem to have a common name.  As the brown discs remind me of an octopus’s suckers I thought we could called it the Octopus Lichen.  Apparently it is quite common.  Not that I have noticed it before. Which is probably more to do with me than the lichen.

  1. By Jove, I think you’ve got it. I was thinking Physcia but there are no “sausages” in your photo that I can see and Physcia has very visible ones. You have such interesting lichens in the South West. Makes me jealous.

  2. Lichen seem to jump out at me in all sorts of places during winter, with no leaves on the trees I can see the branches. I have not been aware of this one before, the furry pale green ones seem to get my attention. Lovely photo of the Octopus lichen.
