Observation 131890: Pertusaria DC.

When: 2013-04-07

Collection location: Jamor, Oeiras, Portugal [Click for map]

Who: zaca

No specimen available

Growing on bark.
The chemical reactions are singular and as far as I could see correspond to a single species of Pertusaria growing on bark: P. flavida. However that species is isidiate. Other species living on bark cited in the British Flora that can cause confusion are: Lecanora explallens, Lecanora alboflavida and Pyrrhospora quernea. The latter I know very well and devoted to it some observations. Concerning the to the two species of Lecanora, they are very different from this material. What could be then?


Chemical reactions.
