Taphrina Pruni

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Taphrina pruni is a fungal plant pathogen that causes the Pocket or bladder Plum gall, a chemically induced distortion of the fruit, producing swollen on one side, otherwise deformed and flattened fruit gall without a stone. The twigs on infected plants may also be deformed with small strap-shaped leaves. T. pruni produces a distinctive tongue-like growth, similar to other closely related species such as Taphrina alni on Alder (Alnus glutinosa) and Taphrina padi on Bird Cherry Prunus padus.
