Lichen mosaic on the underside of a willow branch. (View full size to see the detail.)

I'm having a shot at the ID of the grey, foliose lichen in the centre but would appreciate thoughts on any of the others shown! :-)

Jenny has already identified the one with black apothecia for me as Lecidella elaeochroma and confirmed that many of the pale brown apothecia are likely to be Lecanora species.

I'd be interested if anyone has any thoughts on the darker brown apothecia near the tiny piece of Xanthoria parietina at the top, or at middle right.

Thanks for looking.
