It is characteristic of this fungus that affected fruits cling to the branch over winter, often cemented to- gether in clusters. In this condition they are said to be "mummied" (see Fig. 192). The life story of the brown rot is like that of all moulds : a spore lodges on a fruit, germinates and fills the fruit with its mycelium, and the fruiting hvphte grow out to scatter tlie spores. If the pupils will inoculate a few plums, they will see how rapidly this fungus works, and bv so doing appre- ciate the necessity of picking and burning affected fruits before the spores are cast. Remedies for Afotiilia are pruning to let in light and air, thinning plums and peaches so that no two fruits touch, picking and burning all diseased fruits as soon as detected, and burning all mummified fruits in the fall, since they produce another crop of spores in the Fic. 191.
