Fungi on oak

[kram]

Looking at an oak today, noticed this fungi on a buttress root. When touched, there were visible white spores released.

 

 

Looks like they are well past their best, is it possible to identify them from the photo?

 

Photo of the whole tree, its the closer one.

They look like very old puffballs or eathballs, possibly stump puffball Lycoperdon pyriforme.

I'm back at this one today. The informationI could find, was that puffballs only grow on dead wood, and will not decay a healthy tree.

 

Here is a better photo showing the position on the buttress root.

 

Short video to show the spores, which are now dark green.

 

 

Please ignore my ladder-hedge cutting safety shoes

 

 

Should the fungi give any concern to the long term health of the oak?

 

Thanks
