Abstract: 8 figures. [Study of seven major disjunct populations in the Southern Hemisphere and the evolutionary implications of these patterns of distribution. "Much evidence speaks for a theory that the isolated populations could have been established after the breakdown of the ancient southern continent in the Cretaceous period indicating that the age of certain lichen species can be very old."]
