Normally, immature spores Camptosphaeria are not sigmoid? Correct? I know very little about this kind of Cercophora very close, I think it should be a section of the wall for greater accuracy. I think you've already found Camptosphaeria citrinella?
Regards.
Michel.
Hello Andy and Michel,
With the above mentioned sporesize only tow species as mentioned In the key of the following article http://www.landesmuseum.at/pdf_frei_remote/Sydowia_29_0071-0074.pdf remain C. Citrinella and C. Sulphurea. With a width of 11.78-12.41 um I would go for C Sulphurea
I also have photos of spore developement in the ascus, also there is someting present in top of all asci which I cannot give a name. (dots 1 and 2 in photo 2). It's also present in the ascus of photo 5 of the initial topic report.
