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?

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.

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.

Re : Yellowish apothecias on Sorbus
"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.
