Myco-Phycobiont Interactions within the "Ramalina farinacea Group": A Geographical Survey over Europe and Macaronesia.

ABSTRACT: Ramalina farinacea is a widely distributed epiphytic lichen from the Macaronesian archipelagos to Mediterranean and Boreal Europe. Previous studies have indicated a specific association between R. farinacea and Trebouxia microalgae species. Here, we examined the symbiotic interactions in this lichen and its closest allies (the so-called "R. farinacea group") across ten biogeographic subregions, spanning diverse macroclimates, analyzing the climatic niche of the primary phycobionts, and discussing the specificity of these associations across the studied area. The most common phycobionts in the "R. farinacea group" were T. jamesii and T. lynnae, which showed a preference for continentality and insularity, respectively. The Canarian endemic
