Canoparmelia texana Shield lichen general structure

My organism is Canoparmelia texana is a form of lichen that I found during my trip to arabia mountain. Lichen is a symbiotic organism consisting of a algal and fungal layer. First there is the cortex or outer layer of the lichen thallus protecting the rest of the organism. The upper cortex is made up of fungal hyphae of the upper fungal layer and below that is the algal layer aconospores in a lacunar shape, these conida spores are the primary zone of reproduction for the lichen. Closer to the basement layer is the large medulla hyphal layer filled with the Canoparmelia texana fungus. Next the more congested lower cortex hyphal layer and finally the black apothecia Rhizines.
