    Came across this 2010 photo on Hawthorn and think it could be a very fertile Physcia clementei?

    As that’s a species I’ve only come across a very few times I’d really appreciate any comments for or against!

    Physcia clementei is frequently fertile in Brittany, even fertile this species keeps large characteristic isidia in the center of its thallus which is the case here. Here are some photos from Brittany.

    Thank you Alain – it was the LichenMarins photos that reassured me it probably was Physcia clementei

      Not sure, does that have isidia at all, or are they apothecia initials? The marginal lobes also look different from Physcia clementei on Alain’s photos. Alternative suggestion, but with very limited confidence; an oddly developed Physcia stellaris?

      That was my dilemma too, and I had originally noted it down in 2010 as either Physcia clementei or stellaris.

      Its hard to tell from the photograph as the thallii are covered with apothecia initials but when I came across the photo yesterday I thought the top left thallus did have clumps of rather coarse isidia.

      But yes, looking again the lobes of mine are broader and more over-lapping than those in Alain’s photos, and more like stellaris lobes!
