Capronia muriformis?

French Alps, on Corylus, together with Orbilia trapeziformis, 25.6.24.I would not hesitate if not the spores were partly bigger than allowed, up to about 35 µm long.
The rest seems to fit well - or doesn`t it?
Best regards, Lothar

Re : Capronia muriformis?
I don't think it is C. muriformis based on the ascospore colour and septation pattern. Most spores seem to be shorter than 25 µm, is that correct? I suspect it belongs in the vicinity of C. chlorospora or C. "testudiformis" nom. prov. (https://drive.google.com/drive/folders/0B5SeyOEkxxZhOFBaNzZlaFIyYkk?resourcekey=0-NTIJo7LDBeDZhqQrrk8Utg). Barr also described some morphologically similar species from North America. This is a difficult and little-studied group, so it's not rare to find ambiguous collections...
Best wishes,
Gernot

Re : Capronia muriformis?
Hello Gernot,
thank you very much for your reply. As I remember and wrote, I measured also spores distinctly longer than 25 µm.
I will compare chlorospora and testudiformis.
And yes: you are surely right that it is normal to find specimens that remain unclear.
Best regards, Lothar

Re : Capronia muriformis?
Hello,
I've already noticed that spores that aren't dark brown yet but olive green aren't fully mature yet in all those species.
Cheers - Luc
