I cam across a number of small Eucalyptus blakelyi today with very thick infestation of fungi? or invertebrates (scale insects??) covering much of the trunk. The attached photos show one trunk totally covered, while the other photo shows individual organisms. They are about 10-13mm long, 2mm wide and 1mm thick, with a white slightly gritty surface. When scrapped, the material has a slight brown-red colour - I could not detect any odour nor see any insects. The trees in question are in Bragg St park Hackett and on Mt Majura behind Mackenzie St.
