Objectives of the Course
Lichens are dual organisms composed of a symbiotic relationship between an alga and a fungus. The fungus, usually an Ascomycete, provides the plant its shape, and the alga provides the ability to photosynthesis. Members of the families Cladoniaceae, Stictaceae, Parmeliaceae and Usneaceae have been used as raw materials in the perfume and cosmetic industries. As manufacturing techniques improved, lichen extracts have been combined into toilet powders and scented sachets. Today the principal species still used in perfumery are Evernia prunastri (Oak moss), E. furfuracea and several Ramalinae species. Lichens as Food for humans and other animals; Medicinal problems and uses Lichens as dyes (past and present) Lichens in the perfume industry, Biodeterioration problems, Miscellaneous uses and problems.The distribution of some important Lichens in different regions of Anatolia (Xanthoria, Usnea, Acoraspora etc.)

Course Contents
The definition of Lichens, The morphological and anatomical properties of Lichens, The classifacation of lichens, Determination of some lichens with spesific chemical reagents which are distributed in north-east Anatolia Other species are (or have been) used in “folk medicines”around the world, usually prepared as a tea. Usnic acid has been shown to inhibit the growth of gram+ bacteria Active ingredient in some topical ointments sold in European pharmacies Some lichen fatty acids and carbohydrates have anti-tumor effects in study animals. (Umblicaria, Lasallia) Dyes from Lichen Substances Orchil (purple dyes) –Earliest documented use from ancient Rome as a purple dye or togas using Roccella species from rocks around the Aegean sea shore ––Some Dyes Extracted from Parmelia, Ochrolechia, and Evernia) These extracts are used still to dye wool and produce the “Harris Tweed”of Scotland, especially on the Outer Hebrides Considerable amateur application of lichen .
