Picture taken on the 4th November 2007 at Fontromeu, Oriental Pyrenees, France, very frequent at the base of Pinus uncinata in all Pyrenees (montan stage). It looks like Lecanora conizaeoides but there are always lobes taht differentiates Parmeliopsis ambigua from the above mentioned species.
Parmeliopsis hyperopta is more grey colour. Parmeliopsis ambigua has a lot of soredia.
