Those lichenologists – can’t they settle on something finally?

And we just had a conversation few days ago and I mentioned A.veronensis on Ways of Enlichenment:

Of course that one doesn’t look anything like the species in question here. Brrr… I am going to get my brandy and go to bed… Wake me up when my specimen is identified…

A. cinereoalba, then, which may or may not be synonymous with A. veronensis(!) Oh wait, new development, Knudsen et al 2011 separated A. americana from his previous (2007) broad concept of A. veronensis, and put A. cinereoalba in synonymy with A. americana. … Hard to keep up with!

A.strigata is not listed.

But check out our discussion at observation 91640.

Do you have Acarospora strigata there?

Are there any other “white” species listed? If it were on limestone/dolomite, you would have to worry about normally brown species having unusually heavy white pruina. But on granitic boulders, maybe we can be halfway confident of this id?

From afar this lichen looks like washed out bird poop (bottom photo).
