Found on a fallen needle of Pinus halepensis, diam
I would say that this is (in accordance with Reblova 1999) Helminthosphaeria carpathica.
The spores are little less and the host is not wood. I found them on the rotten liana of Vitis silvestris. Eccentric septa is very typical.
ascospores of your fungus develop an eccentric septum tardily, unlike those of H. carpathica which are already septate in the ascus; they are likewise significantly smaller, thus it might be a different taxon.
Does your last photo show a basal, subicular hypha or a hair originating from the wall?
The setae of H. carpathica are fairly distinctive and might give a good indication.
Good luck!

Hi friends,
I know very well this fungus (Jacques, AG10056), probably the same I've found several times on Pinus sylvestris. I remember having sent material to Andy. Perhaps has he got results ?
Dragisa, I can send my complete description to you in order to compare, if you want.
Alain
Hi Alain, great, send me a description to compare.
the ascospores are also rather reminiscent of H. odontiae, aren't they? Helminthosphaeria is certainly not an easy genus sometimes...
Best wishes,
Gernot
Hi Gernot,
Those of odontiae are more ellipsoid apparently. But the concept of H. odontiae s.l. is probably not sufficient and would merit molecular studies. Probably more than one species in this complex, and you're right, this genus is not easy !
Alain
Yes, I remember these specimens. Unfortunately, the first one (AG 10056) had too few ascomata to sequence (only 8-10 ascomata), and the second recollection (same number), I sequenced a Hyphodontia (corticioid) - probably the basidiomycete that it is growing on. I am happy to try a third time if you would like to collect again and send me more material. These things are difficult to identify and to sequence!!! ;o)
Happy NEw Year,
Andy
Hi Andy,
Thank you for the reply.
You said me these results, I remember now. I wil try to send you fresh material, with a sufficient number of ascomata. Difficult to sequence, but not impossible for you, I think and I hope.
Best wishes, and happy new year.
Alain
I have about 20 ascomata, if you want I can send you, or to try to do here sequencing (Serbia).
Andy
Thanks,
