Seventeen lichen species from the Volga river basin were examined for their phospholipid and fatty acid composition. The total lipids varied from 18.8 to 34.2 mg g −1 dry weight. Major phospholipids found were phosphatidylcholine, phosphatidylethanolamine and phosphatidylglycerol; some species were found to contain phosphatidylinositol and phosphatidyiserine. A phosphorus-containing unidentified lipid was found in three lichen species. Examination of lichen extracts for fatty acid composition showed that the main fatty acids in lichens were 16:0, 18:0, 18:1, 18:2; several species also contained 13:0, 14:0, 15:0, 16:1, 17:0 and some other acids.
