What has happened to this plant?

I don't know what the plant is - maybe a sapling of sime kind. But what has happened? This is not a fuit - too large and irregular shaped. Is it a fungus? Maybe it is an insect parasite like a bedegar (we had lots of bedegars last summer)?

    Hi,

    these are clearly galls on what looks like a small Poplar sapling/sucker. There may be more than one causative agent present here - the rolled leaves (which significantly aren't hairy) and the large infl;ated structure. Lots of different organisms can elicit characteristically shaped responses from their chosen host. I'm afraid I'm not really good at/into galls - many on Poplars seem to be caused by woolly aphids of the genus Pemphigus.

    regards

    Fred
