Capronia muriformis?
Lothar Krieglsteiner, 04-08-2024 19:30
Lothar KrieglsteinerFrench 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
