At this point it will be necessary to refer again to the results which Miss Southworth obtained by inoculating grapes with spores of the apple bitter-rot fungus (Gheospornnn frnct!<j<iiurh Berk.) and apples with the grape ripe-rot fungus (Glasosporium rufo-maculans(Berk.) v. Th.). In both cases a bitter rot or a ripe rot of the respective fruits followed, which led Miss Southworth to regard the bitter-rot fungus and the ripe-rot fungus as one and the same species. The experiments of Halsted (1892) seemed to verify Miss Southworth's experiments. Pig. 5.—Berkeley's apple-rol fungus [Gkeonparmm fructigenum Berk,). [Drawn from the original . figure] and to show that the same fungus caused the ripe rot not only of apples and grapes, but also of quinces, pears, peaches, nectarines, peppers, and other fruits. Summing up tne foregoing, it appears that several fungi causing fruit rots have been described under the impression that they were distinct species. More recent investigations have demonstrated that in all probability the same fungus has caused the various ripe rots of fruits. The different forms variously described as Glasosporium fruc- tigenum, Glceosporium rufo-maculans, Gloeosporium versicolor, and Glasosporium, laeticolor probably differ only in minor characters, such as in the size and form of the spores. The effects which they produce on different fruits vary as to color, size of spots, etc. These differences are readily intelligible in view of the better knowledge which we now.
