Preliminary results on the examination of fungi isolated from CCA treated Eucalyptus power transmission poles were presented at the 10th Annual IRG Meeting. Since then further examination and identification of fungal isolates has been completed together with screening tests for wood decay ability and tolerance to creosote and CCA and its components. Chemical analyses for CCA retention have also been carried out on poles used to obtain fungal isolates. The dominant member of the pole mycota has been used as a tool in laboratory studies on soft-rot decay and preservative tolerance. Morphological details of soft rot have been obtained using the SEM and TEM.
