Unknown from Salix twigs?

Hello everyone.
I'm not sure if it was a branch of Salix, I also take into account Populus.
Hyaline spores, although ascomata looks mature?

Re : Unknown from Salix twigs?
This looks me like Hysterobrevium (H. smilacis ?) - Hyaline multiseptate spores with transverse and longitudal septas and central constriction.

Re : Unknown from Salix twigs?
Hi Sergey
Before publishing this thread I read "A molecular phylogenetic reappraisal of the Hysteriaceae, Mytilinidiaceae and Gloniaceae (Pleosporomycetidae, Dothideomycetes) with keys to world species" and the genre proposed by you seemed very likely due to the construction of spores.
However, she wondering too much spore's length. In combination with a very unusual way of growth (under the bark), I could not decide on it.
Nothing else, however, about more similar features, so I found the name of him as a result; Hysterobrevium cf. smilacis.
Thank you and best regards

Re : Unknown from Salix twigs?
Hi
I think you are wrong with the Hysteriales. It doesn't look the same macroscopically and microscopically. I don't have time to do research, but I would advise you to abandon this way.
Microscopy reminds me more species like : http://www.ascofrance.com/search_recolte/4803
But you have first to give a complete description of ascomata.

Re : Unknown from Salix twigs?
Hi Alain
Thank you for the hint.
I have already seen these mushrooms in this forum, but I could not remind their names.
Only spores fit into Hysterobrevium.
Macroscopic features were completely inappropriate and therefore in the title I wrote "unknown".
Now I know where to look for answers.
Thank you and best regards.

Hi Alan!
>>> Microscopy reminds me more species like : http://www.ascofrance.com/search_recolte/4803
I see evident slits in the ascomata found by Mirek, and on his microphoto with small magnification, but I see no slits on the photo's from Your link. I strongly doubt that here and under the link is the same species.

Re : Unknown from Salix twigs?
Hi Sergey,
I agree with you.
By the way, I never said it was a Dothiora species (but why not ?), but I only wanted to say that microscopy could fit with other fungi.
It will be interesting to further research.

Re : Unknown from Salix twigs?
Gentlemen, why to argue about a few cracked Ascomata;)
I specially showed various variants of Ascomata but these crackled were very little. There may be several reasons for this. I suspect, however, that the cause may be excessive dried substrate. A few weeks did not rain in my area and the substrate is strongly dried. I made photos before hydration.
My knowledge in this topic is quite modest but comparing the features, I come to the conclusion that my collection is the most similar to Dothiora Sphaeroides.
Does anyone have a article about this genre?
The information found on the net is quite scarce :(
I do not have a description of this species, so I can not analyze all the features.
greetings
Mirek

Re : Unknown from Salix twigs?
Thanks to Alain!
I will have something to do on the evening, now I'm at work.
I quickly reviewed the article and it seems that Ascomata's cracks are not something extraordinary in this kind (page 725).

Why few? All ascomata on this macrophoto have more or less developed but evident slit:

Re : Unknown from Salix twigs?
Hi,
Perfect Mirek, you are very close now : you have the litterature, you will carefully observe ascomata, and check all features, and no doubt you will get the answer. Anyway, we're getting closer, and it seems that luckily my proposal wasn't so bad after all :)
In your first pictures it looked like you had two types of ascoma. But now you have analysed the situation well. Froidevaux noted ascomata opening at maturity.
All the best,
Alain

Re : Unknown from Salix twigs?
Hello
It was hard, but I advised the translation.
Alain was right :)
I checked the wood structure. I'm not good at this but the wood is more suitable to Populus.
A few days I kept Ascomata in humid maturing until Conidiophores emerged.
I counted the septum spores.
This species fits my in all details :)
Thank you
