This species was described more than a decade ago (Lendemer & Harris 2007) from numerous collections made throughout eastern North America. Subsequent study with molecular data (Lendemer 2012) demonstrated that the chemoype with fumarprotocetraric acid should be treated as a distinct species, and that was segregated to L. oxybapha.
Why suggested for a Global Red List Assessment?
Lepraria normandinoides is endemic to North America. It is widespread in temperate eastern North America, with disjunct populations in montane southwestern North America (Lendemer 2012, 2013).
Population and Trends
Comprehensive detailed population data are unavailable for this taxon. However, it is common and widespread in many different habitats (Lendemer 2013, Tripp & Lendemer 2020). There is no indication the species is restricted to a narrow range of habitats or substrates.
ASSESSMENT: Least Concern
Given the large number sites where it is extant, large geographic range, large population size, and absence of documented or suspected declines, the species does not meet the thresholds for any threat criteria.
Population Trend: Stable
Habitat and Ecology
This species occurs on the bases and boles of trees, as well as sheltered and protected surfaces of non-calcareous rocks. It occurs across a broad range of forested habitats, elevations and habitat qualities throughout its range.
Boreal ForestTemperate Forest
The primarily threat to this species is urbanization as it does not typically occur in urban areas. Otherwise it appears to be tolerant of disturbance.
Housing & urban areasCommercial & industrial areas
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 urbanization generally on lichens.
