Among natural populations of Parmelia caperata (L.) Ach. and P. rudecta Ach. in an around Ohio, certain patterns of chromium accumulation are apparent. Thalli in industrialized areas have higher chromium levels than thalli in non-industrialized areas. A lichen with a high chromium level will have significantly more chromium in the center of the thallus than in the periphery. Examination of herbarium material of the two species indicates that chromium levels in Ohio lichens have increased since 1893. 11 references, 2 tables.
