These Galls are on the top Willow trees (Probably Crack Willow) The close up shows one of the branches/ galls which fell to ground. The gall was 9 cm end to end and is probably one of the smaller ones as those still on the trees look rather larger - a bit like small birds at a casual glance !

This is the first year we have noticed them having lived here 15 years, so fairly sure this is the first year they have been present.
