Hallo Ueli,

vielleicht eine Alternaria? Das hier: http://www.cbs.knaw.nl/index.php/cbs-biodiversity-series/329-cbs-biodiversity-series-6 habe ich leider nicht.

Hallo Ueli
am I correct in thinking that the long, hyaline 'tail' is the end with the point of attachment? If that is the case and, as it appears, the fungus is forming sporodochia, I don't think its an Alternaria; also Alternaria species (I think) rarely occur on wood like this.

I can't think of many dictyosporous sporodochial hyphomycetes (I'm probably missing something - I'll sleep on it ;-) )

I cannot find another suitable genus of hyphomycetes in "Genera of Hyphomycetes" other than Alternaria. But I rather feel this is a coelomycete for which I do not have the literature at hand. It would be crucial to see on which end the conidia were attached.

My best guess is Alternaria. I belive that the attachment point is the "rounded" end of the conidium, not the "tail" end. You can see, on several conidia, a dark area in the rounded end consistent with the conidium attachment scar of Alternaria.
I don't believe the fungus is forming sporodochia, to me seems that the fungus is growing above something else (a resin drop, an insect body?) and a section of that "fluffy" structure will clarify the doubt. That will also provide the missing "attachment point".

Hello, thank you to Martin, Chris, Walter and Dartanha. Has anyone interested in the mushroom? I alone can not determine the and would send the per post.

Thanks Ueli

I beleive that the rostrum is how the fungus attach itself to the conidiophore wich seem to be lacking here, i highly doubt that this is alternaria , (that and I think that it is really making those sporodochium?) I am not sure what it is neither, but i do not feel it is a coelomycete neither, curious.

If it is truly an alternia however I would be interested in that collection, it look promising.

received it today, it is not an Alternia but i am not quite sure what it is yet, perhaps an thyrostroma or stigmina, the fungus indeed produce distinctive black sporodochium

 the conidia are also attached to the the sporodochia by the beak and are not chained.

 I will try to do a culture of it when I will have time, but right now i am quite busy with my classes, the end of the session is coming soon!
