The endrot fungus has such distinctive characters that it was possible to select cranberries rotted by this fungus alone. A histological study of those selected berries showed that the endrot fungus grows in all parts of the berry except the seeds and the cuticle and is able to penetrate cell walls and protoplasm. A chemical study showed that the sugar content of berries rotted by the endrot fungus is much lower than that of sound fruit. The fungus thus apparently utilizes these sugars.
