Taxonomic Notes: This species was originally included within Lepraria normandinoides as a chemical variant, however, molecular data has since demonstrated that it should be recognized as a distinct species (Lendemer 2012).
Given the large number of sites where Lepraria oxybapha is extant, its large geographic range, potential large population size, and absence of documented or suspected declines, the species does not meet the thresholds for any threatened criteria. Therefore, it is listed as Least Concern.
