Puffball?

Observation - Puffball? - UK and Ireland. Description: Growing on the ground along a footpath. About 2.5 across each sphere, rather irregular in shape. (Additional 8/6/13) I wasn't convinced, so I waited until they grew on and have added more photos. Thanks to Chris Brooks for the initial id.
