today i found these pyrenomycet on a cone of picea.
My first idea was Lophiotrema, but the spores are different in shape and have short appendages.
Any idea what this could be ?
best regards,
Thorben

Re : On picea cone Diaporthe sp. ?
Hi,
First, what about asci ? Bitunicate, or unitunicate ? Please, show us. Then you can eliminate the hypothesis Lophiotrema (bitunicate) or Diaporthe (unitunicate). Thus, a good description of the ascoma (a vertical section helps to see) and of the hamathecium can help to conclude.
Alain
PS : ascospores picture is a bit too bright.

Hi Alain,
thanks for your help.
I just edited and attached the pictures of the asci.
The spore image is now darkened in the attachment and I tried to make a vertical section.
I hope it helps.
best regards,
Thorben
