Observation 49877: Pertusaria amara (Ach.) Nyl.
When: 2010-07-31
Who: zaca
No herbarium specimen

Notes: I had some trouble in realizing the spot tests, because the KC+ red-purple reaction was fleeting. Since I wanted to registred it in a photograph, I had to perform the tests several times, but at the end I succeeded (see last photo attached). Then I came to the name of the species that I’m proposing. As reccomended in the reference given, I made the test for oxalic acid and the taste was very bitter.
