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.
