Re : Hymenoscyphus sp
This should belong in the H. repandus aggregate. Nice croziers here, my H. repandus has mostly simple septate asci. But a few collections had croziers. Your spores are rather wide and resemble H. peruni, which is on wood and which has inamyloid asci.

So an interesting collection! Could you pleas ephotograph the living paraphyses? They should be multiguttulate at high refractivity.
