The thallus of the lichen is 3.1 inch broad and diameter of lobe ranges from 1 to 4 mm (McCune andGeiser, 1997).
They have been reported on rocks, trees, leaves, turtle carapace and inside the thallus of algal lichen (Lakatos et al., 2004; Wu and Bergey, 2017).
These two genera also differ in the size of the thallus and in the degree of calcification (Maslov 1956; Korde 1963).
However, the relationship between lichens and water goes beyond rain levels and, in some lichens, incorporates fog, dew and atmospheric water that interact with temperature and light to define carbon fixation and thallus growth (Gauslaa, 2014; Colesie, Williams, & Budel, 2017).

Morphology of thallus and oospores were studied using sophisticated techniques like scanning electron microscopy to help in species identification.
She covers about lichens, the importance of lichens, finding and collecting lichens, observing and documenting lichens, identifying lichens, preserving and storing lichens, thallus components, thallus types, thallus features, pigments and coloration, the color of a dead lichen, sexual reproduction structures, types of ascomata, asci and spores, substrates where lichens grow, and chemical and ultraviolet tests for identification.
The remainder of the species either reproduce through the dispersal of asexual non-lichenized propagules (Dktyocatenulata alba), or were treated as polymorphic because they are members of the genus Cladonia that produce abundant lichenized propagules together with pyenidia and apothecia on the same thallus. Approximately half (59, 55%) of 108 species found during the inventory were collected fewer than three times, while only a small percentage were commonly encountered (Fig.
There were differences between both stations for this species in term of its morphological features moreover on its thallus colour and prothallus textures.
