This is a very unusual observation. It looks like a bruised apple with some fungal growth. Actually it is around the size of a hawthorn berry.

It is a gall, a directed plant misgrowth. Within it is the green larva of a species of sawfly - elusive as an adult.

Very easily overlooked, so not often reported.

The strange name of Euura pedunculi.
