Gray lichen id ?
Cvenkel Miran, 28-03-2015 00:07
On rock,Slovenia, patch size of mans hand or bigger. At first I thought this is single lichen (gray), but seems, looking on screen, there are two specieses. The color of gray is reproduced OK. The black patches on gray area are randomly scatered around and are rare. Size all about the same as the ones on magnification.

Re : Gray lichen id ?

Hi,


Here it's impossible without microscopy. Acrocordia is easily recognizable with ascospores.


Rock is calcareous ?

Re : Gray lichen id ?
It is calcerous. It is typical karst area.

Re : Gray lichen id ?
I don't believe this is Acrocordia. Species in this genus have big perithecia with visible ostiole by magnification of the photo, but what we see is an arthonioid apothecia.
Best wishes,
zaca

Re : Gray lichen id ?
Ok will get better photos next time. Lots of gray patches this size around there.

Ca me rappelle le Verrucaria calciseda mais je ne le garantirais pas, le groupe des lichens crustacés est très difficile.
