Is this ascomycete hacked?
François Bartholomeeusen, 03-12-2016 15:28
Dear forummembers,

I am glad that the site is available again after it has been hacked. Thousand thanks to those who have solved the problem.
During the same period I examined a find which I think it is a mollisia, but I found abnormal color frb (from cream to dark grey), asci and parafyses. I first thought this Ascomycetes were also hacked!!!

What could be the cause of this abnormality? Can that be due to frost. Is it possible to determine which mollisia it is?
The substrat was Salix and the frb coloured green in KOH.

Thank you in advance for your response.

François

Re : Is this ascomycete hacked?
Hi Francois
this is a great collection. I consider this an chytridiomycete that parasitised the Mollisia. In my article about intrahymenial parasites of Helicogonium (1999, Nova Hedw. 69: 1-71) I also treat this one, but I have no name  and am not even sure about that it is chytridiomycetous.

You have fine photos  but do you also have oil immersion photos of these sporangia?  Could you find any spores inside them? I usually did not see such perhaps because of mmaturity.

Re : Is this ascomycete hacked?
Hi Zotto,

I found this asco on november 23. It was hard to remove the frb's with my knife. I have searched and found some fruiting bodies in my waste. Tomorrow I will do a new attempt to take better pictures.
I have some pictures with a magnification of 1000, can I send them in greater resolution to your private mail?
I was quite surprised with what I saw and have difficulties with the interpretation of this image.
I thought I saw conidia inside. What do you think?

Re : Is this ascomycete hacked?
I suspect that the spores inside the sporangia are globose or a bit angular, and such i do not see on your pics. In the last pic you can see the apical pore which looks like open.

best is tuó study the fungus in water in the living state. perhaps it could be kept in a moist box for some time.

Yes please send me images.
