context_page_description: Taphrina padi is a fungal plant pathogen that induces the form of pocket plum gall that occurs on bird cherry. 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.
context_section_description: These galls are usually known as 'pocket plums', however alternatives are 'starved plums'; 'bladder bullace; and 'mock plums'. The gall appears on the developing fruit, rendering it inedible and resulting in an elongated, curved, hollow, stone-less gall, usually light green in colour at first; turning brown as the gall develops. In T. padi an identification characteristic is that the style persists at the tip of the gall.
  The surface of the gall eventually becomes corrugate and coated with the fungus, showing as a white bloom of ascospore producing hyphae. The totally inedible fruits shrivel and most fall.
