Hi allLong ago we had this Cosmospora on Diatrype bullata here:
http://www.ascofrance.fr/search_forum/5952??
Now, Ingo Wagner found this species again (he had it also 3 years ago), and would lke to know if there are any news about it. He sent me his images.

Re : Cosmospora aff. magnusiana
Yes, it looks like the one I found, and I remember Guy and you have already found it too. http://www.ascofrance.fr/search_forum/8050
It's a very common species.
For it, like for an incredible number of bad-known or new species, we should wait studies.

Re : Cosmospora aff. magnusiana
Dear all,
Cosmospora diatrypicola is not yet published, it is only a working name.
It is a member of the very large group of species occuring on "Pyrenomycetes" at present under investigation.

Re : Cosmospora aff. magnusiana
Thanks all.
I saw that I placed the folder with this species in Dialonectria. Was that an error?

Re : Cosmospora aff. magnusiana
Hi Zotto,
Correct name should be Stylonectria because of the broad, flat apical disc, in Dialonectria, the ascomata have a papilla.

Re : Cosmospora aff. magnusiana
Uff, is that necessary to distinguish so many genera? Even if the phylogeny tells for different groups we need not a genus for every clade :-(

Re : Cosmospora aff. magnusiana
Species of Cosmospora s. l. are too numerous in the world, it is necessary to divide the genus, even if they seem identical, they are different in having morphological characteristics well visible, when many specimens are examined, it is evident that there are several genera.

Re : Cosmospora aff. magnusiana
We have this problem in Orbilia, there are probably 500 species or more. But without sequences you cannot say in quite a lot of cases in ??which group within Orbilia a species belongs. I repeatedly think about splitting Orbilia in several genera, but the problem is always where to stop. Segregation of Hyalorbilia was a necessity, although a few species are not really easy to assign. Segregation of Amphosoma with a few species was a next step, but after that it became quite difficult, and there are still 350 species remaining in Orbilia.
It is actually a matter of taste. In the Luteorubella-group there are two extremely different anamorphs (Anguillospora and Pseudotripoconidium), although the two groups are so closely related that the teleomorphs cannot be distinguished. If you separate here two genera, then Orbilia would break into 20 or more genera.
