Ciboria on branch of Salix
Mirek Gryc, 08-05-2020 19:27
Hi.

Two ascocarps growing on a thin branch of Salix.

I do not have the key for this type but I also do not know the species to which the characteristics of my collection would correspond.
On the Zotto disk I also found the Ciboria collection on Salix. The microscopic features of my collection exactly match the collection presented on the Zotto disk, with one minor exception: in mine, the spores are slightly larger.
In addition, the sporocarps presented on the Zotto disk have long stems and grow on leaves.
I think they can be the same species even despite slight macroscopic differences.
I would like to know your opinion.
Mirek

Re : Ciboria on branch of Salix
Hi Mirek

there are indeed similarities, including the binucleate spores.

But did you compare Ciborinia pseudobifrons? If you go there (now Scleromitrula), there is a form on Populus bark which could be what you have. And it could be that My finds on Salix leaves is the same species.

Re : Ciboria on branch of Salix
Hi Zotto.
I completely agree with your opinion.
I did not find the presence of sclerota, so I did not look in Sclerotiniaceae.
Features of some collections differ in small details from mine but in general, my collection definitely belongs to this group.
Thank you very much and I wish you health!

Hi Zotto, Myrek,  and everyone,


There must be a late paper I overlooked as I did not know such a combination as Scleromitrula pseudobifrons.


If so , would you please share this publication ?


 Amitiés. Michel

Re : Ciboria on branch of Salix
Hi Michel

it seems unbelievable, but the only available sequence of pseudobifrons in GB refers to a Psathyrella :-(

There is also no CBS culture. So we cannot argue with genetics at the moment, which seems quite important in Sclerotiniaceae.

The synonymization of Ciborinia with Scleromitrula was done in 1997, since then there is no home for C. Ciboria pseudobifrons. If the old concept of Ciborinia was not heterogeneous, we must conclude that also C. pseudobifrons is a Scleromitrula.

Re : Ciboria on branch of Salix

OK, thanks,


Among my collections of that species , this is a good opportunity to remember our gorgeous Mellasco meetings and the outings at Le Vanneau where this one was found . THis nowadays sounds as a golden age !

Re : Ciboria on branch of Salix
And it is one of those unsolved cases, because typical C. pseudobifrons on leaves has striate spores.
