Cyanotype on glass (Year 2017)

Lichens are defined as biocoenoses, which are defined as communities of organisms that coexist in a specific environment (Jones, 2019). They are characterised by a symbiotic relationship between a fungus and a partner organism, which can convert light into organic substances by means of photosynthesis, typically involving green algae or so-called cyanobacteria (Smith et al., 2021). Lichens represent a fascinating class of organisms, comprising both algae and fungi.
