Is this Stump Puffball?

Observation - Is this Stump Puffball? - UK and Ireland. Description: Found a large cluster of these on old log under stand of trees on banking next to Loch Libo. The interior was pure white and dense, unlike the other puffball I posted separately. Younger version of the same thing? Or different type of puffball?
