Hypermaritime region from northern California to southern Alaska, and the BC inland rainforest. Possibly also in other temperate rainforests around the world?
Monotypic genus containing a single epiphytic crustose lichen. It is grayish and covered with long, slender, often branched isidia.
Well-lit conifer bark.
Nothing like it: no other crustose lichen has such long slender isidia.
