I do have here a fragment of a branch of Sorbus aucuparia, decorticated and with white rot, lying on the ground in a moist environment at about 1050 m height.
I recorded Lasiosphaeria ovina, Hyalorbilia inflatula and a Hypoxylon (maybe cohaerens).
Between the apothecia of the Hyalorbilia I saw another fungus whose conspicious spores were present in the slides of the Hyalorbilia as well.
My guess is a Cercophora. But isn't this a coprophilous genus? Mature spores seem to have an olive-green sporebody.
Here are some pictures:

Re : Cercophora?
Hi Martin,
The spores meet Immersiella caudata, but, as far as I know, the subapical globulus of this species should be echinulate what I did not observe on your photos. Maybe, Andy Miller will have a better idea.

Bernard

Lieber Martin,
Cercophora ist nicht nur coprophil.

Re : Cercophora?
Thank you Bernard and Peter!
C./I. caudata seems to be a good path since half mature spores have a size (w/o appendices) of 45 µm with a width of 6 to 8 µm.
I will tick it off as such (caudata) unless Andy has a different argument.
Bernard: where is this information on an echinulate globulus?
Would be nice if someone has Lundquist's Nordic Sordariaceae (1972) at hand...
Regards
Martin

Re : Cercophora?
Hi Martin,
I have several collections of Immersiella 'caudata'. But I must admit that I decribed the latest ones only in detail and observed caudate slightly verruculose spores, up to 7-septate, and finely echinulate subapical globuli. Maybe, this taxon differs from the real Immersiella caudata. In Hilber & Hilber (1979) smooth subapical globuli are represented but the type material was apparently not studied. So for the moment being, real identity and variability are unclear to me.

Re : Cercophora?
Dear Bernard,
meanwhile I have seen Lundquist's description. He gives a large picture of the apical globulus that is entierly smooth. Maybe yours is another taxon. Lundquist was not aware of more then 3 lignicolous species of which two of them he just named C. sp. 1 and 2. For the latter he describes the globulus as "verrucose" but he does not give pictures or quotes a published specimen.
Best regards
