Wax apple model based on specimen from Victorian Department of Agriculture, modelled in the museum by model maker Joy Dickins on 11 October 1949. The modek depicts an delicious apple with the disease target spot (Causal organism: Gloeosporium album (Melanconiaceae)).

The display label which accompanies the model notes: this is a disease of the apple which can cause heavy losses in wet autumns. It occurs on the tree in late hanging fruit, and if actual spots have not then appeared they will show up in storage, mainly after two months. It is not essentially a wound parasite, although infection of wounds is common. The entry of spores appears to be mainly via lenticels, and these are larger and more open in wet autumn conditions. The disease appears to be identical with conditions described as bull's eye rot (USA) and perennial canker (on bark). It was first recorded in Switzerland in 1905. Effective control is not known.
