Teichospora? on Robinia pseudoacacia

I found an ascomycete on a twig of Robinia pseudoacacia with muriform spores (The Netherlands) together with the anamorf. Asci bitunicate. The few mature ascospores I found were 17-21 x 9 µm. Conidia avg 17,2 x 7,5 µm Q = 2,31; (13,7-)15,5-18,6(-20,0) x 6,5-8,5 (n=13).
According to the literature C. mirabellensis has ascospores with
So, I think thi is C. elongata. Am I right? A confirmation would be nice.
Best regards,

Re : Cucurbitaria elongata - Camarosporidiella elongata on Robinia pseudoacacia
Hello William,
This cannot be C.elongata, that is much larger fungus.
Is there a reddening around the ascomata and is the anamorph Phoma-like? Also is it associated with Diaporthe oncostoma?
Recently I've collected the same thing, I think it could be Teichospora, where I did not find a match. Perhaps species in Thyridariaceae and Cucurbitariaceae should be checked, but I did not find it in the recently investigated species. This suprised me, because it does not seem to be rare species.
Here I attach my docu and I am looking forward for any advice, I'm probably missing an obvious answer.
Adam

Re : Teichospora? on Robinia pseudoacacia
Hi Adam,
Thanks a lot for your response. I think I found C. elongata on another twig, see http://ascofrance.com/forum/71919/cucurbitaria-elongata-on-robinia-pseudoacacia
This is indeed a big difference in size of the fruiting bodies. Thanks for pointing that out.
That's a wonderful documentation, very nice pictures!
To answer your questions: I saw some reddening around the ascomata. And I found small conidia (3-4,5 x 1-1,5 µm). However, I didn't find Diaporthe oncostoma, yet.
I see that there are several Teichospora species which occur on Robinia: T.
hispida (which has setae on the fruiting body), T. trabicola, T.
mariae and T. pusilla.
Best regards, William

Hi again William,
this should be Neodacampia ulmea. See also Alains find http://www.ascofrance.com/forum?page=1&id=9046
