Recognized by sight: white areoles with multiple apothecia hidden within (“cryptolecanorine”)
Used references: Thomson 2003 Lichens of Wisconsin – only lists one white Acarospora, but it’s a poorly-studied genus in that area, and requires microscopy and C test to have a prayer of keying it out in a broader context

Have we found a bit of rocky ground in North American lichenology??

I just added the last (bottom) picture to this array.

It’s a specimen I eventually picked up a year later to ID. Jim Bennett provided that ID as being A.cinereoalba . He crossed my reference to that being equal to A.veronensis . Apart from that disagreement, ID has been confirmed. Some microscopy provided by J.Bennett: K-; Spores 5×2, many per ascus.

A. cinereoalba = A. veronensis acc. to Knudsen 2007 in Sonoran Desert Flora
