Observation 76960: Lichen P. Micheli

When: 2011-09-18

Collection location: Planalto das Cezaredas, Portugal [Click for map]

Who: zaca

No specimen available

Notes:
Maybe this is better entitled “A lichen mystery”.
The first observation of this lichen was done about one month ago. I returned to the place to ensure myself that what I saw in the photos correspond to the reality. In fact, it does.

At the first sight, it could be a Parmotrema without cilia or rhizines. But, what about the color?
It could also be a Flavoparmelia. But, what about the color?
Some of the lobes seem to have a reticulate. Again, what about the color?
Did I forgot something (that I never learned)?

It does have the appearance of something halfway between Parmotrema and Flavoparmelia. The coloration is way off, like maybe it’s dead? (What would kill such a large thallus so evenly though?)
