Mycoacia uda

I was'nt sure what it was arlanda so thank you

Thank you for the ident arlanda

I do not think it is a lichen, but a resupinate fungus. It could be Mycoacia uda. "Fruit body resupinate, very thin, bright lemon-yellow becoming more ochraceous with age, covered in crowded slender spines", I think it fits!!
