Since it bas been proved that the same funguscauses a decay of maturing grapes without the accom-panying bitterness, the name of Ripe Rot has been ap-plied to the fungus upon both kinds of fruit. That thesame species thrive npon the quince is shown by thefact that the microscopic structure and measurement ofparts are the same, and the decay can be produced in itsnormal form by inoculating the healthy quince withspores that are taken from the grape or apple ripe Fig. 144. KIPE ROT OF QUINCE, FKOM APPLE. A quince, with one side badly infested with the rot, isshown in Fig. 143. The quince being still green, thereis little contrast between healthy and diseased portions;but the latter is evident from the shrunken condition,as well as the numerous spore-bearing pimples to beseen. A specimen of ripe quince fruit showing the sametrouble, but produced by inoculation from the apple, is FUNGI IJS-JURIOUS TO THE QUINCE. 157 seen in Fig. 144. This decay is controlled by the fun-gicides to be later considered. The Quince Blotch.—The most obscure trouble ofthe quince that has been studied is what may be calledthe Quince Blotch.
