The distribution of corticolous lichens had been investigated in the suburb of Seoul in which factories are located densely and Yeosu which located near sea and very few factories are seen in the neighbour. Ten cm point frame was located at random on the trunk of Pinus densiflora, Quercus serrata and Carpinus Tschonoskii from bottom at 0.5m intervals to 8m height of each trees. The occurrence of each species was represented as a percentage of total quadrat frequency and of density. The density of the corticolous lichens was 2.8%, 6.9% and 7.6% at Dongkooneung, Kongneung and Kwangneung apart 15km, 25km and 32km from center of Seoul respectively. In Yeosu district, the occurrence is fairly different from that of Seoul: it is 34.8% and 34.9% at Odongdo and Hoamsan which located within 3km and 5km from the center of Yeosu. The greater frequency of the lichens on the trunk was found at 1~2m height of trees and they were found mostly on the trunk faced south. However, Pertusaria trochophora species occurred more often on the trunk faced east, Graphis scripta on east and north, Parmelia pertusa and Parmelia tinctorum on west side of trunk. Parmelia pertusa increased with increasing height of trees, but Calicium trabinellum and Anzia japonica decreased. Cetraria collata occurred mostly on the middle of above two species. SO2 concentration in the air of Seoul was high enough to eliminate the lichens except Pertusaria trochophora and Graphis scripta.
