Hello together, need some help. Found on 12.05.2019 on the inner side of substrate maybe Typha. Frkp. < 0,5mm, I can't find free spores, but in some Asci you can see spores. No IKI reaction. Maybe Pyrenopeziza, but I have no Key, so maybe someone knows the species.Greetings Petra

Re : Pyrenopeziza cf
Hi Petra
the microscopic appearance is actually that of a Pyrenopeziza, but I would not trust without having seen living elements, especially paraphyses, in order to exclude a Mollisia.
The cuneate spores seem characteristic. For an identification a scale or spore size would be obligatory. I assume the spores are rather small. Inamyloid asci are rare, did you use Lugol or Mellzer? Your photo in iodine suggests an amyloid apical ring, isn't it?

Re : Pyrenopeziza cf
Hi Zotto,
thank you for your opinion, unfortunately I did not find any free spores. The spores in the Ascus have the following dimensions:
5,45 x 1,82, 5,39 x 1,71, 4,75 x 1,85, 5,95 x 2,05, the scale I inserted into the picture. I used Lugol. Unfortunately I cannot judge the photo in iodine correctly whether it is an apical amyloid ring or not. There is an exsikkat available which I could send if necessary.

Re : Pyrenopeziza cf
o.k., this means indeed small spores. With so small asci it is difficult to photograph the apical ring. Beter is to judge directly under the mic. Sorry, I have no time for that,´.
But a suggestion for a species I do not have.
My monocot folder of Pyrenopeziza gives spore sizes, and only one (on Acorus) has so small and narrow spores, but these are not tapered below.

Re : Pyrenopeziza cf
Thank you Zotto. Then it's still called Pyrenopeziza cf.

Re : Pyrenopeziza cf
Hi Zotto,
Is it possible that it is not Pyrenopeziza but Pirottaea imbricata?

Re : Pyrenopeziza cf
P. imbricata I know with apically pr laterally thick-walled hair-cells, I do not see them here.

Thank you Zotto, I suppose another genus is out of the question. LG Petra
