Abstract: 22 figures. [Studies on the control of algal growth in lichen thalli are discussed. "The photobiont cells of non-growing areas are slowed down in their metabolic activity by a, probably, mycobiont-derived inhibitory complex, the molecular basis of which is not yet understood. Phenolic lichen products may, at least in some groups of lichens, be involved in inhibitory mechanisms."]
