Ascomycete with Diaporthe and Gnomonia Characteristics
Peter Thompson, 16-01-2013 22:43
Happy New Year to you all.

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.

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.
