and can’t comment on their range of morphological variation anyway. The pruina may be the key, in which case P. albocaerulescens is likely. But maybe one or more of these others can also sometimes be pruinose…

Between Thomson, Bennett and others, 7 species of Porpidia were identified in WI

P.contraponenda , P.speirea , P.tuberculosa , P.albocaerulescens , P.crustulata , P.herteliana , P.macrocarpa .

Could this be Porpidia albocaerulescens?

Its appearance varies quite a bit depending on how much exposure it gets. But maybe there are additional species of Porpidia
