Ganoderma australe, Southern Bracket. This is the commonest of our large, woody bracket fungi. It attacks living broad-leaved trees, causing a white rot which will eventually kill them, after which it will live for several more years on the dead stumps. It is found at the base of the tree, and is so hard and solid that it is often impossible to break off. The top of the bracket where it joins the tree is dark brown to black, then newer growth below this is brown. The undersurface, consisting of minute pores, is creamy white, bruising brown or grey. The trunk of the tree, lower brackets and nearby foliage is often covered in brown spores, looking like cocoa powder.
