Hi,I want to tell you something about my new page:
www.pilze-ag.npage.de
It is made for a working group, which has meetings in Jülich, western germany (1x per month). As a web admin, I think it would be great to offer some of my asco photos (which are also on the way to be uploaded onto this page). If you want, take a look into the galery (Basidios or Ascos) ;)

The determination for Otidea bufonia and O. leporina are doubtful, but without microscopic data (and also ecological data) it's difficult to name them wih precision. The first one looks like young specimens of O. alutacea. The photo of O. onotica is too highlighted.
I don't recognize Peziza michelii, the photo suggests P. gerardii.
thank you for the comments. The P. michelii was found not far away from the P. gerardii findings, the fbs differ from it in the size (>25mm, P. gerardii 5-18mm), but after watching again at them, I also think about P. gerardii (rough outside, too violett hymenium at all).
The Otideas are not yet microscoped, but I will make this next year (I had a special work this year with bryophil pezizales, I think you saw it in my Octospora findings :D). I will update the page when I have new material and perhaps you can help a bit by the determination of Peziza and Otidea-specimens (I will try it first, just to learn more about it)
regards,
björn
Voici mes remarques:
Planche 1 : (Ascobolus albidus) = A. sacchariferus
Planche 2 : (Ascobolus sacchariferus) = A albidus
-Notes : Je pense en effet qu'il y a inversion des images. Pour information A. albidus et glabre, alors que A. sacchariferus porte des granulations blanches qui font penser à du sucre en poudre ou saccharose, d'où le non de sacchariferus donné à cette espèce par son auteur.
Planches 3 et 4 : P. michelli et p. gerardii sont OK pour moi !
Planche 5 : Pustularia patavina est juste, mais il s'agit d'un vieux synonyme. Le non actuelle que je retiens pour cette discale est Leucoscypaha patavina (Cooke & Sacc.) Svrcek.
Amicalement
René
merci beaucoup pour tes remarques.
Norbert Heine (a specialist for the genus ascobolus) told me, that my determinations with A. albidus and A. sacchariferus are right. The differences are the spore size and the margin (A. albidus without a margin and strongly protuding asci and spores often over 20µm length, A. sacchariferus with a granulated margin and not strongly protuding asci and spores under 20µm length).
René, can you please give me information about the differences between A. albidus and A. sacchariferus? I see a difference, but what is actually A. albidus, and what is A. sacchariferus? Perhaps you have some own experiences and literature about it (van Brummelen?).
regards,
björn
Il est évident que mes remarques ne se basent que sur les photos. Je ne sais d'ailleurs pas pourquoi je suis intervenu, sachant que mes remarques ne pouvaient être que subjectives !!
Il est vrai que les ascospores de A, sacchariferus ne mesurent que jusque vers 20 ?m de long et que celles de A. albidus mesurent 20-36 ?m. L'habitat de A sacchariferus est également assez important, se sont surtout sur excréments de chevreuil, au printemps.
Je vous adresserai, en privé, dès que possible, un scan des descriptions de ces espèces décrites dans la monographie de van Brummelen, ainsi que rapidement de mes photos et dessins de ces espèces.
Cordialement
René
