%X The depsidones hypophysciosporin (methyl 2-chloro-3,8-dihydroxy-1,4,6,9-tetramethyl-11-oxo-11H-dibenzo[ b,e ][1,4]dioxepin-7-carboxylate) (9) and 3-O-methylhypophysciosporin (methyl 2-chloro-8-hydroxy-3-methoxy-1,4,6,9-tetra-11-oxo-11H-dibenzo[ b,e ][1,4]dioxepin-7-carboxylate)(10) have been isolated from the lichen Erioderma phaeorhizum and the structures of these metabolites have been established by comparison with synthetic material. In addition the chroman, vitamin E acetate (14), has been isolated from Erioderma tomentosum, the first reported occurrence of this compound in a lichen.
