Hallo Matthias!
also tot kann ich das nicht erkennen. Erinnert mich aber an Leptodontidium (Phaeohelotium) trabinellum. Das steht bei mir momentan noch in den Pezizellaceae.

Re : Asco on lying Alnus stem
Could this be a lichen? A diminutive form of Coenogonium pineti (earlier Dimerella pineti)?

To Zdenek:

I did not see any algae-symbiont, so I leafe them as tiny Ascos nearby Chlorociboria wich I keep as Exsiccate.

Thanks and greetings!

Re : Asco on lying Alnus stem
Zdenek's idea is good, I think he is right. The slightly capitate paraphyses fit, as do the septate spores. Then the asci must react hemiamyloid as a whole, also laterally (blue after KOH). The thallus of Coenogonium is very reduced.
