The gall is a chemically induced distortion of the fruits, which are swollen, hollow, curved and greatly elongated, without a seed or stone, but retaining the style. The twigs on infected plants may also be deformed with small strap-shaped leaves. "Taphrina padi", a 'tongue fungus', produces a distinctive, elongated, tongue-like growth on Bird Cherry, similar to other closely related species such as "Taphrina alni" on Alder ("Alnus glutinosa") and "Taphrina pruni" on Blackthorn ("Prunus spinosa").

Prunus napaulensis Prunus napaulensis Prunus napaulensis is a species of bird cherry native to the eastern foothills of the Himalayas, including Nepal, Myanmar and China. A tree, it can reach 27m and prefers to grow between 1800 and 3000m above sea level. The fruit is edible, and it is cultivated for its fruit in Assam (and presumably elsewhere). Its wood is used locally for making furniture.
