found first by my wife, some days ago, two days later findplace revisited. Calcareous side of rivulet, in vicinity of Fraxinus (known findplace of Morchella esculenta, Verpa conica etc.).
I hesitate if the type of ascus-amyloidity is WTR? I would say so.
The spores are very variable in size and content, within and also outside the ascus - I found more ellispoid spores about 16-20/9-12 and more elongate ones about 19-23/8-10 µm, the latter likely being the better ripe ones (?). Some of these spores I noted to bear appendages, I noticed this only when preparating in cotton blue/lactophenole. The spores seem to be fully smooth.

I would have tried to identify this as Geosypha ampelina, but I hesitate by some details, especially the amyloidity (should be WT in ampelina), and the vernal growth.

Who can provide me with a proposal to the species?

Yours, Lothar
