Nectria spores but no Nectria

I am new in this forum and do not know very much about ascos.
So I would be very grateful if somebody can help me with my find
During an exkursion of an A. Gminder-Seminar near Goslar (Germany) I have found an Asco. It looks a little bit like a Hypocrea but the spores are reminiscent of Nectria.
Asco J-
Spores 7,5 - 8,5 x 3
With best regards

Re : Nectria spores but no Nectria
Hi,
Perhaps should you look at Nectriopsis genus (first by comparing with oropensoides) ?

Re : Nectria spores but no Nectria
Dear Alain,
I have looked at fotos of Nectriopsis oropensoides (http://www.bender-coprinus.de/pilz_der_woche/2011/_nectriopsis_oropensoides.html)
There I see single perithecia clustered together and surrounded by a hairy felt. Our fungus looked like a Hypocrea species, means it is one large multipertheciate stroma and I have not recognized any hairs/felt/subiculum or whatever. Do the perithecia in Nectriopsis become confluent by age may be?
all the best,Andreas

Re : Nectria spores but no Nectria
Dear Alain, Dear Andreas,
thank you for your support!
I have looked some other pictures of the Genus Nectriopsis, and found some examples of nearly confluent "stromata". Unfortunately my pictures are not very good.
But I heave made an exikat of this find, and may be there are any hairs left? Perhaps anybody can help me with a link to a monographia of Nectriopsis or so. May be I can verfy the spores and Asci.
With best regards
Elmar

Re : Nectria spores but no Nectria
Hello to all,
Alain is right, it is a species of Nectriopsis. It could be N. oropensoides, which is characterised by spinulose hairs surrounding the ascomata. Is this the case for this collection? An image of the hairs (X 100) would be helpful.
Cheers,
Christian

Re : Nectria spores but no Nectria
Hello Christian,
the only structures with terminalhyphaae I am able to find outside the ascomata are this one. They are about 5 micrometer broad.
Thanks and with best regards
