Hi all, I'm having some difficulty with this Orbi

So I've been forced to seek damp places. The bottoms of drying ditches have been full of wonders.
For instance these:

They are 1-1,5 mm wide.
Heres an overview of microscophy:

Mollisia?

But the spores are odd for a Mollisia.
They are about 15-18x6-8 and can have a septa

The asci are about 80-100x10-15.
Paraphyses are 2-3 micrometers wide, widening at tips and have many droplets and are about 20-30 micrometers longer than asci.

Re:It's been hot and dry here
Hi Marja,
The paraphyses full with Vbs and spore shape would rather fit Hymenoscyphus or Tatraea
Did you check the IKI reaction and the presence of a textura intricata in the medulla ?
I would suggest Tatrae dumbirensis though the spores are smaller than usually

Hi Marja,
I have just posted a new ''fiche'' in Ascofrance for Tatraea dumbirensis. There is another one by Enrique Rubio under the synonym Ciboria dumbirensis. The paraphyses do not fit your collection.
Hymenoscyphus remains a suggestion.

Hi Marja & Michel

Tatraea has only faintly refractive VBs in the paraphyses, and curved spores. I believe this is Graddonia coracina. Ascus IKI-reaction should clarify this (Graddonia -, Tatraea strongly blue).

Re:It's been hot and dry here
Hello folks,
I meshed with the specimen by adding too much lugol. So the views were not clear.
But I saw no strong blue reactions, actually was very uncertainly claiming this to be IKI-.
Thought, that I must be asked to tell something of so uncertain observations ;) (But was almoust sure to be forced to do so ;) )
Naturally I'm now overloaded of specimen to be studied and not very willing to take another try...
Even more naturally I've never before met a Graddonia, which I suppose this is :)
Yes, once again a new genus for lucky me :)

Thank you very, very much Michel and Zotto.

This seemed to turn browner in fridge:

Hello Marja,

you can see some macro- and microfotos of Graddonia coracina here:

Re:It's been hot and dry here
Thank you Andreas :)

There seems to be many other photos of interesting species in the gallery, too :)
