Bonjour à tous,
Hi all,
Quelqu'un a-t-il déjà vu le VRAI Gloniopsis praelonga ?
Some one has already seen Gloniopsis praelonga ?
Il apparait régulièrement dans les listings, on le donne régulièrement sur Rubus (voir Ellis & Ellis)
Il se trouve que depuis des années je le traque et je ne l'ai jamais vu rencontrant systématiquement Hysterobrevium smilacis. J'ai plus de 50 observations.
La confusion entre les deux taxons semble établie. Une des raisons est la planche donnée dans Ellis et Ellis, reprise par Eric Boehm dans son website. D'ailleurs dans cet excellent site, Eric montre également la planche de Zogg qui pour moi est le vrai praelonga.
D'où ma question : quelqu'un peut-il me montrer une photo d'ascospores de G. praelonga, identique à la planche de Zogg ?
Tant que je ne l'aurai pas vu, j'aurai du mal à croire l'existence de deux taxons.
J'aimerais enfin savoir si j'ai bien compris ce complexe praleonga-smilacis.
Merci si vous pouvez m'éclairer.
Alain
Pas de récolte de cette espèce chez moi.

Eric Boehm put scans of the drawings in Zogg (1962) on his website: http://www.eboehm.com/gloniopsis.html

So this Zogg-praelonga has more longi- and transsepta than finds in my folder "praelonga" (HB 9187b, 8906a, 8775g, 8746a, 8643k, 7664i)
and also more than in my folder
"praelonga broad-spored + sheath" (8954d, 8690c, 8745b, 7415d)
For all of them I have no correct name.
Zotto
Hi Zotto,
I have only sawn HB7664i, which is very close to praelonga, and HB4640b which is, to my mind, H. smilacis.
Thanks for your reply,
Alain

Hi Zotto,
A lot of thanks, at last I can see photos of collections of praelonga.
I would have classified like you. It's probably the good understanding of this taxa.
Your collections of cf praelonga are very amazing, an ined. Hysterobrevium-Gloniopsis,thus it looks like Rhytihysteron. I have collections of H. mori which show that feature, too.
Thanks again, you help me a lot.

"W-Australia, Acacia. Sp. KOH 22-26 x 11 -> 26-29 x 13-14 µm, with distinct thick gel sheath. Yeollow pigment KOH-dissolved.
- compare Boehm Hysterobrevium constrictum but spores there much smaller!"
All fins of this folder are Australian.
They are australian, ok, have you seen it in Germany ? in Europe ? I've never seen it in France. That's the reason why I called the forum.

8908a: Mecklenburg, on ?Populus. Sp. *21-24 x (8.3-)9-10 µm.
Yellow pigment striking but not well visible on photos.
This looks to me not typical smilacis (?). Does smilacis have the yellow hymenium?
Yes, my 9818 smilacis from Asturias was yellow indeed.
9187b: Czechia, Karlsteijn - you already transferred to smilacis.
8908a has also attracted my attention. Size according to smilacis, but with an "intermediate" shape.
Diificult to give a correct name in that case, even if it's close to smilacis.
We are on the samewave length.
