I'd help please

Ash tree. Epicormic growth was not present two years ago. All pictures are from within .5m of ground level, which has not been changed.

Thanks

....except the first picture.

Same tree; this bit came from decay on the underside of a root buttress. I suspect that it may be kretzschmaria but I'm hoping to be wrong.

No fruiting bodies of Kretzschmaria on this sample.

Thanks David. My suspicion was lead by the black parts on the sample. It is explosively brittle, ie push a pointed implement in and it shatters. 

Not sure what the small grian like things are either? They are approximately 2mm long and separate from the surface on which they're located, as individuals.
