Shield Lichen

Thanks for the help Arlanda. I have posted 4 more close-up views, cropped from the original, but the quality is not good due to the poor light. If there is any other area I can send the raw image direct to you for perusal.

Hi jbstrange2202, thank you for your suggestion, however, it is not a valid suggestion. Firstly, Foliose lichen is not a Common name, it is a term used to describe the entire group of lichens which look like foliage (leaves). Secondly, mycorrhiza is a symbiotic association between a fungus and the roots of a vascular plant, not part of a scientific name, which is made up from the Latin Genus + species. Thirdly cyanobacteria is a phylum of bacteria that obtain their energy through photosynthesis. A phylum is a taxonomic rank between Kingdom and class, so much higher than Genus and species which are the lower end.
