Observation 104922: Pertusaria amarescens Nyl.
When: 2012-08-04
Who: zaca
No herbarium specimen

Notes: This observation took place nearby observation 103418. The similarity of the two makes me believe that they belong to the same species. Quoting from the reference: “In Britain P. amarescens invariably hosts the black apothecia of the lichenicolous fungus Dactylospora saxatilis, the presence of which is virtually diagnostic”. Though not in Britain, this seem to apply to this case, which is one more point in favour of the proposed classification.
