Fig 6 Diseased pineapple about one-third natural size, a a, angle at the base 

 of the fruit where the disease found an entrance owing to the presence of insect 

 wounds- the dark portion shows the nature of the advance of the rot upward 

 Through the fruit. The dark color is due to the formation of the black macrospores 

 of the rot-fungus, the mycelium of the fungus being really considerably in advance 

 of the dark coloration; b, apex of the visibly rotten part It will be noted that the 

 fungus advances most rapidly along the fibrous part of the fruit.
