%X The new depsidones didechlorolecideoidin (1) [methyl 3,8-dihydroxy-1,6-dimethyl-11-oxo-11H-dibenzo[ b,e ][1,4]dioxepin-7-carboxylate] and 4-dechlorogangaleoidin (2) [methyl 2-chloro-3-hydroxy-8-methoxy-1,6-dimethyl-11-oxo-11H-dibenzo[ b,e ][1,4]dioxepin-7-carboxylate] have been detected in the lichens Lecanora argentata and L. californica respectively, and the structure of these metabolites has been established by chromatographic comparisons with synthetic material. The compound (1) has also been shown to occur in the lichen Tylothallia  pahiensis. In addition the dibenzofuran, furfuraceic acid [3,7-dihydroxy-1,9-di(2&#8242;-oxoheptyl)dibenzofuran-2-carboxylic acid] (9) has been isolated from the lichen Phyllopsora  furfuracea, and the structure established by spectroscopic methods.
