Can’t quite see the apothecia

U. krascheninnikovii and U. proboscidea are nearly identical except for the apothecia: the former has smooth disks, the latter “gyrose” (a contorted ridged/fissured texture). Oh, and it looks like there are two analogous species which are “sooty” underneath, U. decussata and U. lyngei. What a mess.
