Observation 53944: Lecanora caesiorubella Ach.

When: 2010-08-26

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

Who: zaca

No specimen available

In my observations MO51245 and MO51245 I gave notice of two Lecanora with a K+ red reaction. This time another species appeared with such reaction, but the red reaction developed with (or preceeded by?) a yellow reaction – see the photo with the chemical reactions, where the yellow is still visible by magnifying the photo.
I think that the macroscopic description given in the reference applies to this specimen, although as it is stated there it is very difficult to separate L. caesiorubella from L. albella. Following the reference, “Lecanora caesiorubella is characterized by rather large apothecia with heavily pruinose disc and thick, flexuose margins”, which I think is the case of this specimen.
