Hysterobrevium smilacis?

Hi,Yesterday I checked my Gloniopsis finding again and made some new photos from it. I have compared it with my G. praelonga and I do not think that this is the same species, because the shape of the spores is different from G. praelonga.
After using a key from E. Boehm it seems as if my recolt is H. smilacis...but is it right? I show you the pics and perhaps you can help me ;)
substrate is Salix sp.
many thanks and regards,
Kazuya

Re:Hysterobrevium smilacis?
Yes, it is.
I recognize the typical form of ascospores.
It's a very common species. I have a lot of various substrates (perhaps more than 15) for it.
I've never seen praelonga. On Rubus, always I have found smilacis for example.
I think a lot of mycologists named praelonga recolts refering to smilacis.
So I would be very interested to see a true praelonga. I read you have a recolt ?
Best regards,
Alain

Re:Hysterobrevium smilacis?
Hi Alain,
thank you for the answer. I had the same thoughts about G. praelonga, after comparing the two species I recognized that my literature about G. praelonga and my own finding have to be redeterminated. My finding "G. praelonga" has spore size 18-22x9-10,5 µm and mostly 3-4 septa. Perhaps is is not G. praelonga and also not H. smilacis, I will show it here:

thanks again, it seems as if it is difficult to find the "real" G. praelonga...

Re:Hysterobrevium smilacis?
Hi you both,
I cannot avoid saying that I never heard of G. smilacis, but have lots of praelonga collections :-) What literature do you both refer?
I compared Kazama's micros with mine, and I concluded, that this might be different because of the large oil drops. I paste here a "typical" G. praelonga. I admit it is frm Australia, but we (Guy and I) have very often seen something similar here.

Re:Hysterobrevium smilacis?
Hi Zotto,
Your additional messages are very interesting, and at once I thank you to show a true Gloniopsis praelonga (probably). I've never seen it under microscope or on photo. In fact, your australian Gloniopsis is perhaps the true praelonga : ascospores obovoid, with obtuse ends, with generally more than 1 vertical septum.
I'm very very happy to see them. Again thanks a lot.
Your recolt on Cornus would be smilacis. Ascospores more asymetrical, with end more acute, as in Kaza-Björn's Gloniopsis.
The reference is Eric Boehm's web site : http://www.eboehm.com . He has made a fantastic synthesis.

Re:Hysterobrevium smilacis?
Hi Alain
yes, in principle I know Erics website, but I had not yet the time to go through all.
Good to hear that. Does peaelonga at all exist in Europe? I have also material of a probably different taxon from Australia with very conspicuous gel sheaths around the ellipsoid spores. But I have now no time to show it, I need to leave to England in a few hours...
Cheers

Re:Hysterobrevium smilacis?
Hi,
my H. smilacis vs. G. praelonga thread seems to be more interesting as expected, especially with these specimens from Australia, also from me many thanks for showing the photos.
After deleting photographics from G. praelonga in my database, there is a hole now that needs to fill with new material, otherwise I have to delete the whole data about G. praelonga. For now my program "I Funghi" is just for myself to determine species (especially Dothideomycetes), but after filling it with own material I will try to release it on DVD or something. Anyway, for now I am happy about any problem which is solved, and H. smilacis - G. praelonga WAS a problem (for me^^)

Kazuya
