An almost cylindrical gall with a slightly broader base (point of attachment to the stem). The gall appeared woody with a rough exterior. A drier gall seen on the same tree appeared to have annular splits.
The apical end of the gall had rounded edges with a depressed centre and perfectly circular hole.
Spotted on ? Eucalyptus blakelyi (Blakely's red gum) in the Weddin Mountains National Park, NSW.
