Lempholemma radiatum
Local name: båndlakrislav
Båndlakrislav (Lempholemma radiatum) is a distinctive crustose lichen characterized by its radiating growth pattern and banded thallus structure that gives it its Norwegian common name. This slow-growing species forms thin, crusty patches on rock surfaces with characteristic concentric bands of gray-green to brownish coloration.

Species Profile
Båndlakrislav (Lempholemma radiatum) is a distinctive crustose lichen characterized by its radiating growth pattern and banded thallus structure that gives it its Norwegian common name. This slow-growing species forms thin, crusty patches on rock surfaces with characteristic concentric bands of gray-green to brownish coloration. It plays an important ecological role in primary succession on bare rock surfaces and provides microhabitat for specialized invertebrates.
Lempholemma radiatum faces significant threats from air pollution and habitat degradation, which severely impact the air quality requirements essential for this sensitive lichen species. Climate change and urbanization further compound these pressures by altering the specific microclimate conditions and substrate availability that this species depends upon for survival.
Key Facts
Habitat & Distribution
This crustose lichen species typically grows on the bark of deciduous and coniferous trees in temperate forests, particularly favoring areas with high humidity and clean air conditions. It is commonly found in old-growth forests and mature woodland environments where air quality remains relatively unpolluted.
Threats
Air pollution and atmospheric contamination
Habitat degradation and fragmentation
Climate change and altered precipitation patterns
Loss of suitable substrate trees
Urbanization and development pressure
