| Abstract | Algal plasmolysis percentages and other morphological characteristics of Parmelia bolliana, P. caperata, P. rudecta, and Physicia millegrana were compared for specimens growing near to and far from a rural coal-fired generating station in south central Wisconsin. SO2 levels were 389 micrograms/cu m, maximum 1 hr level, and 5-9 micrograms/cu m, annual averages. Parmelia bolliana and P. caperata showed evidence of morphological alterations near the station; P. rudecta and Physcia millegrana did not.
