            Peltigera (dog lichens) is a genus of lichenized fungi present on all continents but particularly common, for example, in boreal forests. The use of molecular
                
            In many modern ecosystems, lichens contribute significantly to primary production and nitrogen fixation, inhibit erosion, and efficiently capture and retain moisture. Additionally, they provide food
                
            Interactions within lichen communities are diverse, including the specific symbiotic associations between the lichenized fungi (mycobionts) and photobionts but also interactions between different lichen species
                
            Birds are well known for being important dispersers of many plants, especially via ingested seeds. However, also many other types of organisms may travel attached
                
            Amber deposits are predominantly known from North America, Europe, and Asia, and are considered to be rare on the continents that formed Gondwana. However, more
                
            Tropical mountains harbor a wide range of ecosystems, all providing habitats for various sets of organisms, including lichens. For example, the lichens in the savanna
                
            Non-vascular epiphytes, including bryophytes and lichens, have important roles in tropical montane forest ecosystems in intercepting and storing water, nutrient cycling, and providing habitats and
                
            Representatives of the extant lichenized fungal genera Usnea and Ochrolechia and the lichen-inhabiting (lichenicolous) fungus Lichenostigma were already present in the Paleogene amber forests of
                
            152 new fossil lichens have been discovered from European Palaeogene amber, increasing the total number of known fossil lichens from 15 to 167. Most of
