Assessment Notes
Taxonomic notes
A member of the Porpidia macrocarpa group (Haplocarpon) distinguished from other species of Porpidia by the presence of papillate isidia.
Why suggested for a Global Red List Assessment?
Known only from ultamafic rocks at three localities in Europe. Ultramafic sites in general are under threat from deforestation, mining, exotic species invasions, and atmospheric deposition of pollutants such as heavy metals or previously limiting nutrients such as nitrogen.
Geographic range
One locality in each of Czech Republic, Spain, and United Kingdom
Population and Trends
Unknown. Last collected in 1997
Population Trend:
Habitat and Ecology
Occurs only on exposed ultramafic rocks
Threats
Ultramafic substrata are undergoing drastic changes due to ever-expanding development, deforestation, mining, exotic species invasions, and atmospheric deposition of pollutants such as heavy metals or previously limiting nutrients such as nitrogen (Williamson & Balkwill 2006; Rajakaruna & Boyd 2008; Harrison & Rajakaruna 2011). Such changes can have a drastic impact on the biota of these unique habitats.
Conservation Actions
Research needed
Surveys in support of conservation efforts should be encouraged to document the wealth of biological diversity frequently being lost from such sites worldwide. These sites should be better explored to generate data for effective conservation planning.
