My #photo shows #lichens #Xanthoria #parietina (Teloschistales) and #Physcia #adscendens (Caliciales) on a branch of #tree Carpinus betulus. The #symbiosis of #mycobiont (fungus) and #photobiont (algae) = lichens has still much #research potential. The authors C. Lorenz et al. (2023) e.g. have successfully tested X. parietina for use in #space under #Martian conditions.
