SUMMARY Three species of lichen: Hypogymnia physodes (L.) Nyl., Pseudevernia furfuracea (L.) Zopf and Usnea filipendula Stirt. with differing sensitivities to SO 2 were examined for differences in their ability to carry out sulphite oxidation. The factor responsible for sulphite oxidation is not connected with the metabolic activity of thalli and probably the oxidation does not take place in reaction with O 2− The rate of sulphite oxidation may well depend on the content of heavy metals in the thalli.
