Lepraria normandinoides

Described by Lendemer and Harris (2007).

Lepraria normandinoides is a leprose, green-algal lichen that occurs in forests across much of eastern North America in the eastern United States and adjacent areas of Canada with disjunct, isolated populations in the Sky Islands of the southwest and Black Hills of South Dakota. It is most abundant in the Appalachian and Ozark mountains. Because of its widespread distribution, abundance, and the lack of documented threats, it is considered apparently secure.

Lepraria normandinoides occurs in North America, in Canada from southern New Brunswick through Ontario, and in the United States from Maine to Georgia and New Mexico to South Dakota (Lendemer 2013, GBIF 2025). The species is most abundant in the Appalachian and Ozark Mountains of the eastern United States, and occurrences in New Mexico and South Dakota are restricted to isolated mountain ranges. Range extent was estimated using herbarium specimens collected between 1985 and 2025 (Lendemer 2013, GBIF 2025, RARECAT 2025).

By applying a 1 km separation distance to herbarium records documented between 1985 and 2025, it is estimated that there are more than 300 occurrences rangewide (GBIF 2025, RARECAT 2025).

Although threats are not widely documented, Lepraria normandinoides is potentially threatened by development, logging, gas and oil extraction, and other threats in some places. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, and affinity for typically abundant habitats.
