Given the large number of sites where it is extant, large geographic range, potentially large population size, and absence of documented or suspected declines, Lepraria normandinoides does not meet the thresholds for any threatened criteria. Therefore, it is listed as Least Concern.
This species was described over a decade ago (Lendemer and Harris 2007) from numerous collections made throughout eastern North America. A subsequent study using molecular data (Lendemer 2012) demonstrated that the chemotype with fumarprotocetraric acid should be treated as a distinct species and it was segregated to Lepraria oxybapha
Lepraria normandinoides is endemic to North America. It is widespread in temperate eastern North America, with disjunct populations in montane south-western North America (Lendemer 2012, 2013)
Population and Trends
Comprehensive detailed population data are unavailable for this taxon. However, it is common and widespread in a wide variety of habitats (Lendemer 2013, Tripp and Lendemer 2020). There is no indication this species is restricted to a narrow range of habitats or substrates.
Population Trend: stable
Habitat and Ecology
This species occurs on the bases and boles of a wide variety of trees, as well as sheltered and protected surfaces on non-calcareous rock. It occurs across a broad range of forested habitats, elevations, and habitat qualities throughout its range.
The primary threat to this species is urbanisation as it does not typically occur in urban areas. Otherwise, it appears to be tolerant of disturbance.
Many sites where Lepraria normandinoides
occurs are located on public lands and in protected areas where it is incidentally protected. This species would benefit from broader awareness and training as to the impacts of urbanisation on lichens in general; and further research would be beneficial to get a clearer idea of the population size and trends.
