Re : Hypoxylon rubiginosum?
Ruud thinks the wood is softwood.
I tried woodanatomy, but only got a tangential section.
I wonder if this is softwood.

Re : Hypoxylon rubiginosum?
Hi Riet,
do you think Robinia is possible (hardwood) for this site?
Best

Re : Hypoxylon rubiginosum?
Hi Martin,
Ruud did not notice any Robinias and he does not know if they were ever there, but Robinia could be, microscopically it looks very similar.
So we can exclude softwood :-)
Thank you very much!
