For small, dull/pruinose, pale, gray, non-sorediate, non-isidiate, non-lobulate things on bark on the west coast:

Physcia aipolia – conspicuously mottled white surface, medulla K+y
Physcia stellaris – mottled or not, lightly pruinose or not, medulla K-
Physcia biziana – heavily pruinose (obscuring surface), medulla K-

Since there is little mottling and little pruina, P. stellaris looks best from where I sit.
