Dear Carlos

Nice collection and drawing! About the anamorph I can say little. I never saw an anamorph of Helicogonium with such long conidia, but why not. To identify the teleomorph needs some further characters: The ascus base looks like arising from croziers but it could also be a subbasal protuberance without connection. So it is important to look also for the ascogenous hyphae just below the ascus cell if there are true croziers present with a complete arch. Further, the small conidia that arise from the ellipsoid ascospores should be studied at the stage when they are formed, because usually they emerge at the wider end of the clavate ascospores but sometimes at the narrower end. In your case, the ascospores look ellipsoid: are they always without a clear broader and narrower end, i.e. +/- homopolar?

These two states occur in the hymenium of a Mollisia? Are there paraphyses present and perhaps also some Mollisia-asci? Is it a lignicolouos Mollisia?

The asci and host remind me of H. mollisiophilum, but I cannot remember to have seen such a bifurcate ascus base here.

best regards

Tres grand merci Zotto, je vais regarder une autre fois tous ça avec tes documents dans DVD (grand valeur). Mollisia lignicolous, taxa posiblement pas decrit; anamorfo exento, pas dans l'hymenium, il y a un subiculum noir, sur le subiculum Mollisia et l'anamorphe et une tres petit Urceolla (pas etudié encore, Ungicularia ou similar).

J'ai des nouvelles observations, une autre anamorphe, cette fois dans les Mollisia, cette fois ce Helicogonium et je pense l'autre du autre dessins c'est une autre chose.

Dans quelques apotecia il y a asques helicogonium mais aussi quelques asques Mollisia, il y a aussi des parafises (toujours) et il ya l'anamorphe (pas comun). J'ai une autre dessing 2005 je crois.

amitiés

Cher Carlos

yes, the left side of your drawing should be the anamorph of the asci right, while the paraphyses among them belong to the Mollisia.. The spores drawn above the asci, did you see them within the asci? Are they germinating ascospores? I never saw a phialide on the ascospores as I recall, always the conidia were formed directly on the ascospores. About the spores on the left I am a bit unsure where they belong. Helicogonium-anamorphs produce minute conidia (similar as there ascoconidia) from terminal phialides. See the attach (Helic. parorbiliopsidis)
Zotto

Exact, a gauche c'est l'anamorfo.
Oui, à l'intérieur de l'asques je vois l'ascospores et peux voir à l'intérieur et exterieur (charrues d'ascas accidentel ?) la formation de conidies.
J'envoie un dessin de 2005

Au moins pour mon cela c'est une avance, maintenant j'ai placé l'anamorfo réel d'Helicogonium avec le votre aide

A possibility would be Helicogonium prunicolae, a species I have seen only once, in Mollisia prunicola. It has rather broad ascospores and asci with croziers. But the ascoconidia are cylindrical, not ovoid as in your drawing. Did you try to identify the Mollisia? What is the host of the Mollisia?
