1. how can i differentiate Mollisia from Pyrenopeziza? What is microscopically the difference?
2. I searched the Internet, since I do not have any literature about Mollisia and Pyrenopeziza, except using asco-sonnenberg. Any hint is welcome.
Thanks, I hope this is an appropriate question in this high-profile forum.
Regards

Re : Yellowish apothecias on Sorbus
I am not sure about the family of this fungus. Important is to study the excipulum, best in a section, but also squash mount may be helpful.
Is it hyaline or brown? Is it of globose cells or elongate?

Thanks a lot, I have added a squash image.

Re : Yellowish apothecias on Sorbus
Very pale, but cells roundish.
On your first micro I see one paraphsyis. It lacks the refractive content of a Mollisia, so that group can safely be excluded.
How large are the apos, 0.3 mm?
Such "characterless" fungi are difficult to classify.

Hello Thomas!
You can try to better represent the elements from the marginal area and the paraphyses.

Tx Ingo, attached the suggested picture.

Re : Yellowish apothecias on Sorbus
Woww, this changes all. Now the paraphyses contain long, strongly refractive vacuoles and the excipulum is more brownish.
The spores look lke having a few minute drops near each end.
I fear I do not know. A bit similar is Chlorosplenium chlora but that is up to 1-2 mm large.

"It lacks the refractive content of a Mollisia, so that group can safely be excluded." ... and why not a Mollisia now? Refractive vacuolar bodies and dark globulosa?

Re : Yellowish apothecias on Sorbus
Hi Lotharm Chlorosplenium mighg be difficult to delimit from Mollisia s.l., so with te VBs it can actually be one, despite the minute apos. A light brown (not dark) excipulum is possible in the genus.
