Usually a sterile lichen overgrowing bryophytes and hummus on rock substrates. It can resemble members of the Lepraria neglecta group. Sometimes, it is accompanied by the related M. lignaria. In the Czech Republic, M. leprosula most often occurs in border mountains, where it typically grows on screes and on boulder slopes in mountain corries. However, it may be found also at lower elevation; for example, in the České středohoří uplands, Lužické hory Mts and Ralsko region, it is locally common on screes on vulcanites.taxonomic classification:
