Lepraria diffusa is hardly identifiable in the field. Without the TLC analysis, it may be mistaken for L. eburnea or L. nivalis. The lichen prefers calcareous substrates, including pure limestones, where it usually grows on bryophytes in partly exposed or rain-protected places. Apart from bryophytes, it may be found also on rocks, less often on soil or bases of trees with higher bark pH. The species is rather rare but widespread in Europe. In the Czech Republic, L. diffusa is rare but on calcareous rocks may be locally abundant.
