Bladder plum is a fungal disease similar to peach leaf curl. In cool wet spring weather it spread by rain splash and infects fruit making them spongy and rotten.
Bladder plum infection starts with a small blister on the fruit. The blister quickly grows and soon covers the whole fruit and they may grow to ten times their normal size. The fruit goes white/grey, gets a spongy texture and becomes covered with velvety, gray fungal spores. Eventually infected fruit dry out and turn black.
