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
The presence of apical sheath on the ascospores is typical. The type of amyloid reaction is often intermediate between WT and WTR. In your collection, this is close to WTR, but the ring is not very thick as observed in Peziza spp. s. str.
thank you very much for confirmation and comments.
Yours, Lothar
