Observation 103417: Pertusaria flavicans Lamy
When: 2012-07-28
Who: zaca
No herbarium specimen

Notes: In the Identification key to Pertusaria in Europe and the Mediterranean the chemistry given is:
“C+ yellow, KC+ yellow,UV+ orange”,
whereas Irish lichens refers:
“Thallus: K-, C+ orange, KC+ orange, P-, UV + orange; Soralia: C+ orange”,
which is more likely my specimen. I made the UV test on the collected peaces of soralia and saw an orange/red reaction.
It should be mentioned that P. flavicans doesn’t appear in the paper used with a “checklist” for this location (see the Notes of the location).
