Umbilicaria cylindrica, commonly known as the fringed rock tripe, is a leafy lichen found in cold, high-altitude and polar regions across the globe. It forms roughly circular thalli measuring between 2–10 centimetres and is easily recognised with a dark upper surface bordered by a fringe of fine, hair-like projections. As one of the first colonisers of bare rock, it paves the way for more complex communities in areas exposed to intense ultraviolet light. The species is particularly abundant in Arctic–alpine environments, where it can form extensive patches on exposed boulders and rock

Sticta canariensis is a species of cyanolichen in the family Peltigeraceae. It is known for its ability to form photosymbiodemes – distinct morphological forms resulting from symbioses with either green algae or cyanobacteria. The species exhibits two main forms: a bright green chloromorph with dichotomously branched lobes and brown fruiting bodies, and a dark blue-grey cyanomorph with phyllidia and white mottling. It has a disjunct distribution across Atlantic Europe and Macaronesia, where it primarily grows as an epiphyte in laurisilva forests but can also be found on soil and rocks near

Pannaria is a genus of lichen-forming fungi in the family Pannariaceae. These lichens form leaf-like, scaly, or crusty patches that typically arrange themselves in loose rosettes on tree bark in humid forests. Most species partner with nitrogen-fixing cyanobacteria, though some contain green algae instead. The genus was established in 1828 and now includes about 80 recognized species found worldwide, particularly in tropical and subtropical regions.
