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).

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.
