Re : Daldinia cf. macrospora ?
Hi Pavol,
such overmature stromata are hard to determine. The grey green pigments occur in species of the petriniae complex. The stromata are not typical for D. petriniae and rather suggest D. lloydii.
Do not take into account those huge ascospores, they originate from few-spored asci.
Try to find it again in good mature condition.
Cheers,
Jacques
