coastal lichen for id please

[Naturenutz]

found these lichen on the high tide rocks.All different sizes,some very large but this was about 60mm.

[Naturenutz]

after further research the nearest ive seen is xanthoria parietina.

I'm probably amongst the world's worst at lichen ID's, but I think this may be in the area of Caloplaca verruculifera

Alan S or Jenny S will probably be your best chance of a correct ID.

Mike.

Thanks mike , ill look that one up and await further help .

[ladyhawk]

xanthoria elegens maybe

[JennyS]

Xanthoria calcicola is a possibility but I can't enlarge your photo enough to see whether there are isidia (tiny outgrowths containing both fungal and algal cells) on the lobes

would loading a bigger size photo be any benefit jenny.

Not an identification I'm afraid but a bits of a heads up - I've just come across this on the NHBS web site - could help with all those lichens we'll see on our visits to the seaside this year.
