Rank ReasonsHeterodermia hypoleuca is a common and globally widespread foliose lichen that grows on the bark of hardwood trees and on rocks in some segments of its range. It is common over large areas of its geographic distribution, including eastern North America. Rangewide, there are over 300 occurrences known. Additional information is needed to evaluate threats and trends.
Range Extent CommentsHeterodermia hypoleuca has a global distribution that includes east Asia, eastern North America, South America, east and south Africa, Papua New Guinea, and Australia (Lendemer 2009, Elix 2010, O and S 2019). Range extent was estimated using specimens collected between 1983 and 2024 (GBIF 2024).
Occurrences CommentsThis lichen is common in eastern North America (Lendemer 2009). By applying a 1 km separation distance to specimen records documented between 1983 and 2024, it is estimated that there are over 300 occurrences rangewide (GBIF 2024).
Threat Impact CommentsPotential threats to this lichen are air pollution and any activity that results in the removal of host trees, which could have subsequent impacts to the lichen community due to changes in light and humidity levels.
