Gernot FriebesHi,I am interested to hear your opinion on this Le
Found on rabbit dung.Species was only visible because the asci were errupted from the side of the fruitbody breaking through the dung layer.
Asci: 300-400x25-27.5 um; 8-spored; bi-seriate; short stalk.
Spores: 4-celled; 48-52x11.5-12.5 um; parallel germ slit (not in one line); small hyaline sheath surrounding the spores; second cell has a different form (a broad trapezium) while the third cell is cilindrical; both end cells conical.
in my opinion is this Sporormiella grandispora.
Greetings Peter.
I also think it is S.grandispora although the measures given by Joop asci are larger than in the description.
Michel.
the argument of measure I see in the phenomenon, that some bitunicate asci become a larger shape under determined circumstances. I don't know the name of the phenomenon.
Greetings Peter.
Thank you Peter and Michel.
I do agree with you both about the species now but the bigger size of the asci cannot be explaned.
Nevertheless the asci already left the fruitbody (not through the ostiole) when I discovered the species and I carefully placed it under a cover glass in water for examination without any pressure.
Are you sure that these asci are bitunicate Peter because those double wall asci only occur in pseudothecium and species with a perithecium do normally have unitunicate asci. But it would explane the enlargement of asci because bitunicate asci take on water when the outer shell splits open when spores are ripe and enlarge
By the way even within the tangle of asci in the photo the minimum length of the asci was 290 um.
best wishes
Chris
