Je pensais avoir ramassé un joli asco vert, d'1 mm de diamètre, mais la micro ne montre pas d'asques ni paraphyses etc...
En grattant l'endroit suposé de l'hymenium que des myriades de petites spores(?) rondes de 1 à 2 mu .
Peut être un anamorphe ou un ......?mycètes.
une idée?
amitiés

Sur la première image les conidiomes sont jaunes, donc il s'agit peut-être de Pycnidiella resinae

Re:anamorphe ?
j'ai oublié de dire qu'il peut aussi s'agir de Biatorella resinae parasité par autre chose, il faudrait voir les conidiophores de plus près.

Bonsoir,
Pardon pour la brutalité de ma question mais je suis allé trop vite dans ma manipulation...
Je pensais aussi à la résine, mais il devrait y avoir des asques si c'est Biatorella !
Amicalement,
Alain

Re:anamorphe ?
malgrès plusieurs lames pas l'ombre d'un asque.
ci joint ce que je crois être des conidiophores.(cf également la 2e photo envoyée plus haut)
merci pour votre aide

Re:anamorphe ?
Huiiii! This "discomycete" bothers me since a long time. I still consider it to be the anamorph of a not further known helotialen discomycete, but a relation to Sarea cannot be excluded.
During my revision of type material of "Orbilia" species I found a name for it:
Orbilia crocina (Mont. & Fr.) Sacc., Syll. Fung. 8: 632 (1889)
≡ Peziza crocina Mont. & Fr., in J.P.F.C. Montagne, Ann. Sci. nat., Ser. 2, 5: 289 (1836) [non Peziza crocina Berk. & Curt. 1868, = Calycella crocina (Berk. & Curt.) Dennis]
The fungus is mitosporic, having a gelatinised excipulum, narrow phialides in a palisade, and subglobose conidia measuring 1.8-2.2 x 1.5-1.9 µm. Although the excipulum looks similar as in Bisporella, it is probably not the same as this Calycella crocina.
It seems strange that this probably not rare species seems totally neglected in the literature. Montagne's description appears to be erroneous concerning the microdata, describing asci with numerous globose spores which easily "s'échappent.". Perhaps Montagne saw the teleomorph which actually sounds like Sarea resinae. But the anamorph of Sarea forms globose pycnidia without a hymenium. So it would be a good idea to compare more thoroughly the Sarea anamorph with this.
I attach Montagne's description.
