Ascomycete with Diaporthe and Gnomonia Characteristics
Peter Thompson,

I have found a sample of an ascomycete which has a mixture of characteristics associated with the genera Diaporthe and Gnomonia, as follows:
Diaporthe - Growing on a woody substrate (Lonicera periclymenum) and black stromatic lines surrounding the fruit bodies.
Gnomonia - Perithecia with ostiolar 'necks' extending well above the substrate and spores with short appendages at each end.
I have attached a photograph of the fruit bodies and a sketch of the microscopy.
I wonder if anyone might know the identity of the fungus.
Thank you,
Peter.

Re : Ascomycete with Diaporthe and Gnomonia Characteristics
Dear Peter,
If the host is really Lonicera periclymenum, it could be interesting.
Are you sure it is Lonicera ? Could it be Hedera helix ? Because it looks like Diaporthe hederae.

Re : Ascomycete with Diaporthe and Gnomonia Characteristics
Hello Alain,
Thank you for your reply.
Yes, Hedera helix was also growing at the same location. At the time, I checked for any horizontal outgrowths from the dead stems and did not find any, so convinced myself that Lonicera was more likely.
I see that the microscopy matches Diaporthe hederae very closely. I think that I must have misidentified the substrate.
Best wishes,
Peter.

Yes probably.
Thank s for your post, it's a nice photo of Diaporthe hederae.
