I found this Geopora :Â
In a dry stream wihth rich sand in a wood in The Netherlands.
The tree he was standing by is a oak and corylus.Â
The apothecia are 1 cm til 4,5 cm.Â
Spores are: 24 - 30 mu 12-14 mu with 2 drops and little drops between it.Â
99% of all the spores in the asci and beyond have 2 drops. rare 1 drop.Â
Parafysen septated and sometimes curved.Â
Q= 1,98
Could it be Geopora foliacea maybe?Â
Sincerely, Ronald MorsinkÂ

Re : Geopora?
You're right for the genus (although I prefer the name Sepultaria for the epigeous species) but I cannot say for the species. I have no experience of a species with such cylindrical ascospores.
This is a difficult genus which needs a serious revision. The species forms ectomycorhizae, so ecology is important.
You should keep your collection in herbarium for future studies...
