A sorediate form of M. affinis, characterised by yellow soralia containing usnic acid. In this Atlas, the taxon is left apart because of its different morphology and reproduction strategy. In the Czech Republic, ranges of these two entities is overlapping and their abundances are equalling. Interestingly, M. alpinus occasionally grows on sandstone rocks in the Kokořín region and in the Adršpach-Teplice rock complex. Its presence in other sandstone areas is probable.
