Lichens and Branches

The branches are the branches of a Madrone tree (Arbutus menziesii), one living and one dead. The dead branch has two kind of lichens growing on it, the branched lichen which appears to be the Farinose Cartilage Lichen (Ramalina farinacea) and the flat grayish lichen which appears to be the Hooded Bone (Hypogymnia physodes). The photo was taken in Sharpe Park on Fidalgo Island while there with my son-in-law last December and if anyone knows better than I as to the identification of the lichens I'd appreciate a correction.
