Re : ascomycete on Agave from Portugal
Hi Lothar,

Take a look at Phaeosphaeriopsis obtusispora, as the spores blacken in Lugols, the size fits and the key was the central cell slightly larger than the rest. Looked at Leptospharia also as this is a key feature of spores in that genera also.  Or in and around Phaeosphaeriaceae.  Just an option perhaps,

Re : ascomycete on Agave from Portugal
Hello Tony,
thank you very much for this hint that - I will follow it in the next days. At first glance it looks if it could be a "Hit the bull's eye". 
Best regards, Lothar

I think better P. agavensisl
Using the key in Thambugala & al. (Phylogeny and morphology of Phaeosphaeriopsis triseptata sp. nov., and Phaeosphaeriopsis glaucopunctata) I come to P. agavensis, because the ascomata are partly multilocular (as can bee seen in the section in my second picture). The spore width fits better, too, even if the spore length is a little bit large.

Thanks again, Tony!
