Re : Yellow apothecia on Salix with septated spores
In dead state quite impossible to identify. Is it bark/wood or leaf? Apo diameter? Lugol reaction of ascus apex perhaps positive (red)?

What shape have the hairs? How wide the paraphyses, did they contain something when alive? The spores could be guttulate, but in MLZ this is not visible. Perhaps in KOH or water.

Re : Yellow apothecia on Salix
Dear Hans-Otto, you are completely right, that was insufficient info. I tried to update all information.

Re : Yellow apothecia on Salix
The living spores are now very well visible. If you have no Lugol, I would appreciate KOH-pretreatment (of course difficult with such minute apos). Maybe then they would be MLZ-blue. The narrow paraphyses seem to exclude a Pezizellaceae.

Now the hair shape and size is unclear, also the substrate. Such minute apos usually occur on leaves, but you surely know.

Re : Yellow apothecia on Salix
I did the pretreatment with KOH, and then Lugol, there is no positive reaction...
Hans-Otto Baral, 03-06-2026 20:27
Re : Yellow apothecia on Salix
I thought you have no Lugol. Then it would have been good without KOH. It is the matter about hemiamyloidity.

For my database query I need to know if it was on a leaf or on wood/bark. Could be something like Aivenia.

It is on a 1cm thick decorticated branch of Salix
