Physiological and chemical analysis for identification of some lichen extracts

Identification of lichen species is an interesting area that use morphological and chemical analysis. In the presented study, eight lichen species were collected and identified based on different procedures. Anatomically, they were examined for their growth type and thallus color, presence or absence of vegetative parts (Rhizines and cilia), and sexual reproductive parts (Their types of Apothecia and Perithecia, if any). Spot tests, TLC with different visualization method and micro-crystallography were chemical analysis applied to lichen fragment and their extract to help the identification of species. Finally, all studied species were identified as; Heterodermia leucomelos (L.) Poelt., Cladonia subradiata (Vainio) Sandst., Parmotrema tinctorum (Delise ex Nyl.) Hale, Leptogium sp. (Ach.) Gray., Parmotrema crinitum Choisy., Herpothallon sp. Tobler, Parmotrema reticulatum (Taylor) M. Choisy and Ramalina celastri (Sprengel) Krog & Swinscow. This is a rare organized report on identification of lichens based on both morphological and chemical investigations
